If you enable this, each backup part will be emailed to you as soon as it's ready. This is useful if you are low on disk space (disk quota) when used in conjunction with Delete archive after processing. When using this feature we suggest having 10Mb plus the size of your part for split archives free in your account. The drawback with enabling this option is that if the email fails, the backup fails. If you don't enable this option, the email process will take place after the backup is complete and finalized. This ensures that if the email process fails a valid backup will still be stored on your server. The drawback is that it requires more available disk space.

If enabled, the archive files will be removed from your server after they are emailed to you. Very useful to conserve disk space and practice the good security measure of not leaving your backups on your server.

The email address where you want your backups sent to. When used with GMail or other webmail services it can provide a cheap alternative to proper cloud storage.

A subject for the email you'll receive. You can leave it blank if you want to use the default. However, we suggest using something descriptive, i.e. your site's name and the description of the backup profile.

If you enable this, each backup part will be uploaded as soon as it's ready. This is useful if you are low on disk space (disk quota) when used in conjunction with Delete archive after processing.

When this option is set to No (default) the backup will not stop if uploading the backup archive to the remote storage fails. A warning will be issued, but the backup will be marked as successful. You can then go to the Manage Backups page and retry uploading the backup archive to remote storage. This is useful if the backup failed to upload because of a transient network or remote server issue, or a misconfiguration you have fixed after the backup was taken. This also acts as a safety net: if your site breaks after the backup is taken you can restore from the latest backup archive which failed to upload —in whole or in part— to remote storage.

When this option is set to Yes the backup will stop as soon as Akeeba Backup detects that it failed to upload a backup archive to the remote storage. If you have set Process each part immediately to No (default) that will be it; the backup attempt will be marked as Failed and all backup archive files of this backup attempt will be removed. If you have set have set Process each part immediately to Yes and some backup archive files have already been uploaded to the remote storage they will be left behind when the backup attempt is marked as Failed; you will have to remove them yourself, manually, outside of Akeeba Backup. In either case you will not have a valid backup. If your site breaks before you can rectify the problem you are left without a backup.

Considering that the vast majority of the rare occurrences of backup upload failures we see are transient issues, we consider this option to be dangerous as it can unexpectedly leave you without a valid backup when you need one. It is far better to leave this setting set to No and monitor your backups for warnings. There are extremely few use cases where this option makes sense (e.g. taking a backup of a site on a server without enough space for both the backup archive and the site to coexist, a situation which is anyway problematic should you need to restore the backup). We very strongly recommend not enabling this option unless you have a compelling use case and understand the implications of potentially being left without a valid backup at random.

If enabled, the archive files will be removed from your server after they are uploaded to Amazon S3.

Your Amazon S3 Access Key. Required unless you run Akeeba Backup inside an EC2 instance with an attached IAM Role. Please read about this below.

Your Amazon S3 Secret Key. Required unless you run Akeeba Backup inside an EC2 instance with an attached IAM Role. Please read about this below.

If enabled, an encrypted connection will be used to upload your archives to Amazon S3.

	Warning
	Do not use this option if your bucket name contains dots.

When this option is disabled Akeeba Backup will use the old Amazon S3 endpoint domain names which only support IPv4. When this option is enabled Akeeba Backup will use the new Amazon S3 endpoint domain names which support both IPv4 and IPv6.

It is strongly recommended to leave this option enabled if you are using Amazon S3 proper (instead of a third party service which is S3 compatible). If your server supports IPv6 it will result in slightly faster uploads to Amazon S3. Even if your server doesn't support IPv6 yet this is a good forwards-compatible option, i.e. when your server is upgraded to support IPv6 your connection to Amazon S3 will be upgraded as well.

The name of your Amazon S3 bucket where your files will be stored in. The bucket must be already created; Akeeba Backup can not create buckets.

Warning

DO NOT CREATE BUCKETS WITH NAMES CONTAINING UPPERCASE LETTERS. AMAZON CLEARLY WARNS AGAINST DOING THAT. If you use a bucket with uppercase letters in its name it is very possible that Akeeba Backup will not be able to upload anything to it. More specifically, it seems that if your web server is located in Europe, you will be unable to use a bucket with uppercase letters in its name. If your server is in the US, you will most likely be able to use such a bucket. Your mileage may vary. The same applies if your bucket name contains dots and you try using the Use SSL option, for reasons that have to do with Amazon S3's setup. Please note that this is a limitation imposed by Amazon itself. It is not something we can "fix" in Akeeba Backup. If this is the case with your site, please DO NOT ask for support; simply create a new bucket whose name only consists of lowercase unaccented Latin characters (a-z), numbers (0-9) and dashes.

Please select which S3 Region you have created your bucket in. This is MANDATORY for using the newer, more secure, v4 signature method. You can see the region of your bucket in your Amazon S3 management console. Right click on a bucket and click on Properties. A new pane opens to the left. The second row is labelled Region. This is where your bucket was created in. Go back to Akeeba Backup and select the corresponding option from the drop-down.

	Important
	If you choose the wrong region the connection WILL fail.

Please note that there are some reserved regions which have not been launched by Amazon at the time we wrote this engine. They are included for forward compatibility should and when Amazon launches those regions.

This option determines the authentication API which will be used to "log in" the backup engine to your Amazon S3 bucket. You have two options:

This option determines how the API will access the Bucket. If unsure, use the Virtual Hosting setting.

The two available settings are:

The directory inside your Amazon S3 bucket where your files will be stored in. If you want to use subdirectories, you have to use a forward slash, e.g. directory/subdirectory/subsubdirectory.

	Tip
	You can use backup naming variables in the directory name in order to create it dynamically. These are the same variables as what you can use in the archive name, i.e. [DATE], [TIME], [HOST], [RANDOM].

Since Akeeba Backup 3.2, uploads to Amazon S3 of parts over 5Mb use Amazon's new multi-part upload feature. This allows Akeeba Backup to upload the backup archive in 5Mb chunks and then ask Amazon S3 to glue them together in one big file. However, some hosts time out while uploading archives using this method. In that case it's preferable to use a relatively small Part Size for Split Archive setting (around 10-20Mb, your mileage may vary) and upload the entire archive part in one go. Enabling this option ensures that, no matter how big or small your Part Size for Split Archives setting is, the upload of the backup archive happens in one go. You MUST use it if you get RequestTimeout warnings while Akeeba Backup is trying to upload the backup archives to Amazon S3.

Select the storage class for your data. Standard is the regular storage for business critical data. Please consult the Amazon S3 documentation for the description of each storage class.

Note

Glacier and Deep Archive storage classes are much cheaper but have long delays (several seconds to several hours) in retrieving or deleting your files. Using these storage classes is not compatible with the Enable Remote Quotas configuration option and the Manage Remotely Stored Files feature in the Manage Backups page. This is a limitation of Amazon S3, not Akeeba Backup. We strongly recommend not using these storage classes directly in Akeeba Backup. Instead, use one or more Lifecycle Policies in your Amazon S3 bucket. These can be configured in your Amazon S3 control panel and tell Amazon when to migrate your files between different storage classes. For example, you could use Intelligent Tiering in Akeeba Backup together with the Maximum Backup Age quotas and Remote Quotas to only keep the last 45 days of backup archives and the backups taken on the 1st of each month. You could then also add two lifecycle policies to migrate backup archives older than 60 days to Glacier and archives older than 180 days to Deep Archive. This way you would have enough backups to roll back your site in case of an emergency but also historical backups for safekeeping or legal / regulatory reasons. Feel free to adjust the time limits to best suit your business use case!

Enter the custom endpoint (connection URL) of a third party service which supports an Amazon S3 compatible API. Please remember to set the Signature method to v2 when using this option.

By default, Akeeba Backup uploads each backup archive to B2 in small "chunks". B2 will then stitch together these chunks to create one, big backup archive. Each chunk transfer takes a small amount of time, preventing timeouts. The downside is that some hosts have weird outbound proxy setups in front of their servers, getting in the way of multipart uploads. In these cases you will see near instant chunk transfers but nothing being uploaded to BackBlaze B2. If this happens you will need to disable multipart uploads by selecting this box and use a fairly small part size for split archives to prevent timeouts while the upload is in progress.

The size of each chunk during a multipart upload as explained above.

Your DreamObjects Access Key

Your DreamObjects Secret Key

If enabled, an encrypted connection will be used to upload your archives to DreamObjects. In this case the upload will take slightly longer, as encryption - what SSL does - is more resource intensive than uploading unencrypted files. You may have to lower your part size.

	Warning
	Do not enable this option if your bucket name contains dots.

The name of your DreamObjects bucket where your files will be stored in. The bucket must be already created; Akeeba Backup can not create buckets.

DO NOT CREATE BUCKETS WITH NAMES CONTAINING UPPERCASE LETTERS OR DOTS. If you use a bucket with uppercase letters in its name it is very possible that Akeeba Backup will not be able to upload anything to it for reasons that have to do with the S3 API implemented by DreamObjects. It is not something we can "fix" in Akeeba Backup. Moreover, if you use a dot in your bucket name you will not be able to enable the "Use SSL" option since DreamObject's SSL certificate will be invalid for this bucket, making it impossible to upload backup archives. If this is the case with your site, please don't ask for support; simply create a new bucket whose name only consists of lowercase unaccented latin characters (a-z), numbers (0-9) and dashes.

When enabled Akeeba Backup will automatically convert the bucket name to all lowercase letters. This addresses a common problem where you've created a bucket named mysite but try to enter it as MySite in Akeeba Backup. This discrepancy causes the backup to fail to upload to DreamObjects. If, however, you have created a bucket with any number of uppercase letters please disable this option and make sure that the bucket name you have entered matches exactly the name of the bucket in DreamObjects, including lowercase and uppercase letters.

If enabled, the archive files will be removed from your server after they are uploaded to Dropbox.

The application will always try to upload your backup archives / backup archive parts in small chunks and then ask Dropbox to assemble them back into one file. This allows you to transfer larger archives more reliably.

When you enable this option every step of the chunked upload process will take place in a separate page load, reducing the risk of timeouts if you are transferring large archive part files (over 10Mb). When you disable this option the entire upload process has to take place in a single page load.

	Warning
	When you select Process each part immediately this option has no effect! In this case the entire upload operation for each part will be attempted in a single page load. For this reason we recommend that you use a Part Size for Split Archives of 5Mb or less to avoid timeouts.

This option determines the size of the chunk which will be used by the chunked upload option above. You are recommended to use a relatively small value around 5 to 20 Mb to prevent backup timeouts. The exact maximum value you can use depends on the speed of your server and its connection speed to the Dropbox server. Try starting high and lower it if the backup fails during transfer to Dropbox.

Before you can use the application with Dropbox you have to "link" your Dropbox account with your Akeeba Backup installation. This allows the application to access your Dropbox account without you storing the username (email) and password to the application. The authentication is a simple process. First click on the Authentication - Start here button. A popup window opens, allowing you to log in to your Dropbox account. Once you log in successfully, click the blue button to transfer the access token back to your Akeeba Backup installation.

You need to do this on every backup profile you want to link to Dropbox, even on the same site.

Check if you are a member of a team using Dropbox for Business and want to use your team's folder to store backups. Remember to prefix the Directory below with the name of your team folder. For example, if Dropbox' web interface shows an “Acme Corp Team Folder” in the Files page and you want to put your backups in a folder called “Backups” inside it you should use the Directory name Acme Corp Team Folder/Backups, not just Backups.

The directory inside your Dropbox account where your files will be stored in. If you want to use subdirectories, you have to use a forward slash, e.g. /directory/subdirectory/subsubdirectory.

This is the short-lived access token to Dropbox. Normally, it is automatically fetched from Dropbox when you click on the Authentication - Start Here button above. If for any reason this method does not work for you you can copy the Token from the popup window.

It is very important that you DO NOT copy the Access Token to other backup profiles on the same or a different site. It will not work. Instead, please use the Authentication - Start here button on each profile and site you want to connect to Dropbox.

This is the long-lived refresh token to Dropbox. It is used to refresh the access token every time it expires. Normally, it is automatically fetched from Dropbox when you click on the Authentication - Start here button above. If for any reason this method does not work for you you can copy the Token from the popup window.

It is very important that you DO NOT copy the Refresh Token to other backup profiles on the same or a different site. It will not work and will only cause the Dropbox connection to be lost on your site. Instead, please use the Authentication - Start here button on each profile and site you want to connect to Dropbox.

If you enable this, each backup part will be uploaded as soon as it's ready. This is useful if you are low on disk space (disk quota) when used in conjunction with Delete archive after processing. When using this feature we suggest having 10Mb plus the size of your part for split archives free in your account. The drawback with enabling this option is that if the upload fails, the backup fails. If you don't enable this option, the upload process will take place after the backup is complete and finalized. This ensures that if the upload process fails a valid backup will still be stored on your server. The drawback is that it requires more available disk space.

When this option is set to No (default) the backup will not stop if uploading the backup archive to the remote storage fails. A warning will be issued, but the backup will be marked as successful. You can then go to the Manage Backups page and retry uploading the backup archive to remote storage. This is useful if the backup failed to upload because of a transient network or remote server issue, or a misconfiguration you have fixed after the backup was taken. This also acts as a safety net: if your site breaks after the backup is taken you can restore from the latest backup archive which failed to upload —in whole or in part— to remote storage.

When this option is set to Yes the backup will stop as soon as Akeeba Backup detects that it failed to upload a backup archive to the remote storage. If you have set Process each part immediately to No (default) that will be it; the backup attempt will be marked as Failed and all backup archive files of this backup attempt will be removed. If you have set have set Process each part immediately to Yes and some backup archive files have already been uploaded to the remote storage they will be left behind when the backup attempt is marked as Failed; you will have to remove them yourself, manually, outside of Akeeba Backup. In either case you will not have a valid backup. If your site breaks before you can rectify the problem you are left without a backup.

Considering that the vast majority of the rare occurrences of backup upload failures we see are transient issues, we consider this option to be dangerous as it can unexpectedly leave you without a valid backup when you need one. It is far better to leave this setting set to No and monitor your backups for warnings. There are extremely few use cases where this option makes sense (e.g. taking a backup of a site on a server without enough space for both the backup archive and the site to coexist, a situation which is anyway problematic should you need to restore the backup). We very strongly recommend not enabling this option unless you have a compelling use case and understand the implications of potentially being left without a valid backup at random.

If enabled, the archive files will be removed from your server after they are uploaded to Google Drive

The application will always try to upload your backup archives / backup archive parts in small chunks and then ask Google Drive to assemble them back into one file. This allows you to transfer larger archives more reliably.

When you enable this option every step of the chunked upload process will take place in a separate page load, reducing the risk of timeouts if you are transferring large archive part files (over 5Mb). When you disable this option the entire upload process has to take place in a single page load.

	Warning
	When you select Process each part immediately this option has no effect! In this case the entire upload operation for each part will be attempted in a single page load. For this reason we recommend that you use a Part Size for Split Archives of 5Mb or less to avoid timeouts.

This option determines the size of the chunk which will be used by the chunked upload option above. You are recommended to use a relatively small value around 5 to 20 Mb to prevent backup timeouts. The exact maximum value you can use depends on the speed of your server and its connection speed to the Google Drive server. Try starting high and lower it if the backup fails during transfer to Google Drive.

If this is the FIRST site you connect to Akeeba Backup click on this button and follow the instructions.

On EVERY SUBSEQUENT SITE do NOT click on this button! Instead copy the Refresh Token from the first site into this new site's Refresh Token edit box further below the page.

Warning

Google imposes a limitation of 20 authorizations for a single application –like Akeeba Backup– with Google Drive. Simply put, every time you click on the Authentication - Start Here button a new Refresh Token is generated. The 21st time you generate a new Refresh Token the one you had created the very first time becomes automatically invalid without warning. This is how Google Drive is designed to operate. For this reason we strongly recommend AGAINST using this button on subsequent sites. Instead, copy the Refresh Token.

If your account has access to Google team drives you can select which of these drives you want to connect to. However, this process is a bit more complicated than it sounds.

First, you need to use the Authentication - Start Here button to connect to Google Drive. Second, you need to click the Save button in the toolbar to apply the Google Drive connection information. Third, you can select your drive using the dropdown. This is the only method for selecting a drive which is guaranteed to work.

Please remember that the list of drives is returned by Google's servers. If you do not see a drive there your problem has to do with permissions and setup at the Google Drive side of things. In this case please be advised that we are not allowed to help you; Google forbids us from providing help about its products through our site. You will have to peruse their community support forums to seek assistance about setting up your team drives to be visible by your Google Drive account.

The directory inside your Google Drive where your files will be stored in. If you want to use subdirectories, you have to use a forward slash, e.g. directory/subdirectory/subsubdirectory.

	Tip
	You can use backup naming variables in the directory name in order to create it dynamically. These are the same variables as what you can use in the archive name, i.e. [DATE], [TIME], [HOST], [RANDOM].

Warning

Object (file and folder) naming in Google Drive is ambiguous by design. This means that two or more files / folders with the same name can exist inside the same folder at the same time. In other words, a folder called My Files may contain ten different files all called "File 1"! Obviously this is problematic when you want to store backups which need to be uniquely named (otherwise you'd have no idea which backup is the one you want to use!). We work around this issue using the following conventions: If there are multiple folders by the same name we choose the first one returned by the Google Drive API. There are no guarantees which one it will be! Please do NOT store backup archives in folders with ambiguous names or the remote file operations (quota management, download to server, download to browser, delete) will most likely fail. If a folder in the path you specified does not exist we create it If a file by the same name exists in the folder you specified we delete it before uploading the new one.

This is the temporary Access Token generated by Google Drive. It has a lifetime of one hour (3600 seconds). After that Akeeba Backup will use the Refresh Token automatically to generate a new Access Token. Please do not touch that field and do NOT copy it to other sites.

This is essentially what connects your Akeeba Backup installation with your Google Drive. When you want to connect more sites to Google Drive please copy the Refresh Token from another site linked to the same Google Drive account to your site's Refresh Token field.

Warning

Since all of your sites are using the same Refresh Token to connect to Google Drive you must NOT run backups on multiple sites simultaneously. That would cause all backups to fail since one active instance of Akeeba Backup would be invalidating the Access Token generated by the other active instance of Akeeba Backup also trying to upload to Google Drive. This is an architectural limitation of Google Drive.

If you enable this, each backup part will be uploaded as soon as it's ready. This is useful if you are low on disk space (disk quota) when used in conjunction with Delete archive after processing.

If enabled, the archive files will be removed from your server after they are uploaded to Google Storage.

When enabled, Akeeba Backup will upload your backup archives in smaller chunks, the size of which is specified in the Chunk Size option belo. This is the recommended methods for larger (over 10Mb) archives and/or archive parts.

Select the maximum size of a file chunk Akeeba Backup will try to upload at once. It's recommended to keep relatively low, e.g. 5 to 20 Mb depending on the transfer speed between your server and Google's servers.

The name of your Google Storage bucket where your files will be stored in. The bucket must be already created; the application can not create buckets.

DO NOT CREATE BUCKETS WITH NAMES CONTAINING UPPERCASE LETTERS. If you use a bucket with uppercase letters in its name it is very possible that the application will not be able to upload anything to it.

Please note that this is a limitation of the API. It is not something we can "fix" in the application. If this is the case with your site, please simply create a new bucket whose name only consists of lowercase unaccented latin characters (a-z), numbers (0-9), dashes and dots.

The directory inside your Google Storage bucket where your files will be stored in. If you want to use subdirectories, you have to use a forward slash, e.g. directory/subdirectory/subsubdirectory.

You can use backup naming variables in the directory name in order to create it dynamically. These are the same variables as what you can use in the archive name, i.e. [DATE], [TIME], [HOST], [RANDOM].

Change the storage class of the uploaded backup archives. “None” means that the files will be stored with the default storage class specified in your bucket. Please note that options other than Standard may be cheaper to store but they may incur additional fees if you download them or delete them. Please consult Google for pricing information.

Open the JSON file you created in the Initial Setup stage outlined above. Copy all of its contents. Paste them in this field. Make sure you have included the curly braces, { and }, at the beginning and end of the file respectively. Don't worry about line breaks being "eaten up", they are NOT important.

Your Google Storage Access Key, available from the Google Cloud Storage key management tool.

Your Google Storage Secret Key, available from the Google Cloud Storage key management tool.

If enabled, an encrypted connection will be used to upload your archives to Google Storage. In this case the upload will take longer, as encryption - what SSL does - is a resource intensive operation. You may have to lower your part size. We strongly recommend enabling this option for enhanced security.

	Warning
	Do not enable this option if your bucket name contains dots.

The name of your Google Storage bucket where your files will be stored in. The bucket must be already created; Akeeba Backup can not create buckets.

DO NOT CREATE BUCKETS WITH NAMES CONTAINING UPPERCASE LETTERS. If you use a bucket with uppercase letters in its name it is very possible that Akeeba Backup will not be able to upload anything to it. Moreover you should not use dots in your bucket names as they are incompatible with the Use SSL option due to an Amazon S3 API limitation.

Please note that this is a limitation of the API. It is not something we can "fix" in Akeeba Backup. If this is the case with your site, please DO NOT ask for support; simply create a new bucket whose name only consists of lowercase unaccented latin characters (a-z), numbers (0-9) and dashes.

When enabled Akeeba Backup will automatically convert the bucket name to all lowercase letters. This addresses a common problem where you've created a bucket named mysite but try to enter it as MySite in Akeeba Backup. This discrepancy causes the backup to fail to upload to Google Storage. If, however, you have created a bucket with any number of uppercase letters please disable this option and make sure that the bucket name you have entered matches exactly the name of the bucket in Google Storage, including lowercase and uppercase letters.

The directory inside your Google Storage bucket where your files will be stored in. If you want to use subdirectories, you have to use a forward slash, e.g. directory/subdirectory/subsubdirectory.

	Tip
	You can use backup naming variables in the directory name in order to create it dynamically. These are the same variables as what you can use in the archive name, i.e. [DATE], [TIME], [HOST], [RANDOM].

You cannot set a chunk size lower than 1Mb or higher than 60Mb because of OneDrive's API restrictions. We recommend using 4, 10 or 20Mb (tested and found to be properly working).

Before you can use Akeeba Backup with OneDrive you have to "link" your OneDrive account with your Akeeba Backup installation. This allows Akeeba Backup to access your OneDrive account without you storing the username (email) and password to. The authentication is a simple process. First click on the Authentication - Start Here button. A popup window opens, allowing you to log in to your OneDrive account. Once you log in successfully, you are shown a page with the access and refresh tokens (the "keys" returned by OneDrive to be used for connecting to the service) and the URL to your site. Double check that the URL to your site is correct. Copy the Access Token and Refresh Token from the popup window to Akeeba Backup's configuration page at the same-named fields. Afterwards you can close the popup.

When using this feature we suggest having 10Mb plus twice the size of your part size for split archives free in your account. If you don't enable this option, the upload process will take place after the backup is complete and finalized. The drawback to that is that it requires more available disk space.

When this option is set to No (default) the backup will not stop if uploading the backup archive to the remote storage fails. A warning will be issued, but the backup will be marked as successful. You can then go to the Manage Backups page and retry uploading the backup archive to remote storage. This is useful if the backup failed to upload because of a transient network or remote server issue, or a misconfiguration you have fixed after the backup was taken. This also acts as a safety net: if your site breaks after the backup is taken you can restore from the latest backup archive which failed to upload —in whole or in part— to remote storage.

When this option is set to Yes the backup will stop as soon as Akeeba Backup detects that it failed to upload a backup archive to the remote storage. If you have set Process each part immediately to No (default) that will be it; the backup attempt will be marked as Failed and all backup archive files of this backup attempt will be removed. If you have set have set Process each part immediately to Yes and some backup archive files have already been uploaded to the remote storage they will be left behind when the backup attempt is marked as Failed; you will have to remove them yourself, manually, outside of Akeeba Backup. In either case you will not have a valid backup. If your site breaks before you can rectify the problem you are left without a backup.

Considering that the vast majority of the rare occurrences of backup upload failures we see are transient issues, we consider this option to be dangerous as it can unexpectedly leave you without a valid backup when you need one. It is far better to leave this setting set to No and monitor your backups for warnings. There are extremely few use cases where this option makes sense (e.g. taking a backup of a site on a server without enough space for both the backup archive and the site to coexist, a situation which is anyway problematic should you need to restore the backup). We very strongly recommend not enabling this option unless you have a compelling use case and understand the implications of potentially being left without a valid backup at random.

If enabled, the archive files will be removed from your server after they are uploaded to Azure.

Should we use multipart uploads for large archive files? Archive files over the Chunk Size threshold will be uploaded in multiple chunks, each one at most as big as the Chunks Size.

Important

Microsoft Azure BLOB Storage has a hard limit of up to 50,000 parts per uploaded file. If your backup archive is bigger than 50,000 times the Chunk Size it's not possible to upload it using the multipart. In this case Akeeba Backup will try to upload it all at once which might lead to a timeout. If this happens we strongly recommend setting up the Part Size for Archive Splitting in the Archiver Engine options, setting that to a value under 2000Mb.

How much of the backup archive to transfer at once. Please refer to the Multipart Uploads information above the image.

The storage account name for your Microsoft Azure subscription. See the instructions above the image.

The key1 value for accessing your Microsoft Azure subscription. See the instructions above the image.

Please leave this enabled. It tells Akeeba Backup to use the secure HTTPS protocol to communicate to Microsoft Azure. Disabling it will use the insecure HTTP protocol, without any encryption of your communication between your site's server and Microsoft Azure. Support for using unencrypted HTTP might be removed by Microsoft without prior warning.

If enabled, the archive files will be removed from your server after they are uploaded to the FTP server.

The hostname of your remote (target) server, e.g. ftp.example.com. You must NOT enter the ftp:// protocol prefix. If you do, Akeeba Backup will try to remove it automatically and issue a warning about it.

The TCP/IP port of your remote host's FTP server. It's usually 21.

The username you have to use to connect to the remote FTP server.

The password you have to use to connect to the remote FTP server.

The absolute FTP directory to your remote site's location where your archives will be stored. This is provided by your hosting company. Do not ask us to tell you what you should put in here because we can't possibly know. There is an easy way to find it, though. Connect to your target FTP server with FileZilla. Navigate to the intended directory. Above the right-hand folder pane you will see a text box with a path. Copy this path and paste it to Akeeba Backup's setting.

The relative path to the initial directory, it will be created if it doesn't exists. Leave it empty to upload the archives directly inside the initial directory. You can use all of the backup naming variables, e.g. [HOST] for the hostname of the site being backed up.

If your remote server supports secure FTP connections over SSL (they have to be Explicit SSL; implicit SSL is not supported), you can enable this feature. In such a case you will most probably have to change the port. Please ask your hosting company to provide you with more information on whether they support this feature and what port you should use. You must note that this feature must also be supported by your originating server as well.

Normally you should enable it, as it is the most common and firewall-safe transfer mode supported by FTP servers. Sometimes, you remote server might require active FTP transfers. In such a case please disable this, but bear in mind that your originating server might not support active FTP transfers, which usually requires tweaking the firewall!

Some badly configured / misbehaving servers report the wrong IP address when you enable the passive mode. Usually they report their internal network IP address (something like 127.0.0.1 or 192.168.1.123) instead of their public, Internet-accessible IP address. This erroneous information confuses FTP information, causing uploads to stall and eventually fail. Enabling this workaround option instructs cURL to ignore the IP address reported by the server and instead use the FTP server's public IP address, as seen by your web server. In most cases this works much better, therefore we recommend leaving this option turned on if you're not sure. You should only disable it in case of an exotic setup where the FTP server uses two different public IP addresses for the control and data channels.

If enabled, the archive files will be removed from your server after they are uploaded to the SFTP server.

The hostname of your remote (target) server, e.g. secure.example.com. You must NOT enter the sftp:// or ssh:// protocol prefix. If you do, Akeeba Backup will try to remove it automatically and issue a warning about it.

The TCP/IP port of your remote host's SFTP (SSH) server. It's usually 22. If unsure, please ask your host.

The username you have to use to connect to the remote SFTP server. This must be always provided

The password you have to use to connect to the remote SFTP server.

Many (but not all) SSH/SFTP servers allow you to connect to them using cryptographic key files for user authentication. This method is far more secure than using a password. Passwords can be guessed within some degree of feasibility because of their relatively short length and complexity. Cryptographic keys are night impossible to guess with the current technology due to their complexity (on average, more than 100 times as complex as a typical password).

If you want to use this kind of authentication you will need to provide a set of two files, your public and private key files. In this field you have to enter the full filesystem path to your private key file. The private key file must be in RSA or DSA format and has to be configured to be accepted by your remote host. The exact configuration depends on your SSH/SFTP server and is beyond the scope of this documentation. If you are a curious geek we strongly advise you to search for "ssh certificate authentication" in your favourite search engine for more information.

If you are using encrypted private key files enter the passphrase in the Password field above. If it is not encrypted, which is a bad security practice, leave the Password field blank.

	Important
	If the libssh2 library that the SSH2 extension of PHP is using is compiled against GnuTLS (instead of OpenSSL) you will NOT be able to use encrypted private key files. This has to do with bugs / missing features of GnuTLS, not our code.

For example, if you have a shared folder named backups and you want to create a subdirectory inside it based on the site's name, you need to enter backups/[HOST] in the directory box. If a Sync Folder by the name "backups" is not found, a directory named "backups" will be created inside your Magic Briefcase folder. Yes, it's more complicated than, say, DropBox – but that's also why SugarSync is more powerful.

If you enable this, each backup part will be uploaded as soon as it's ready. This is useful if you are low on disk space (disk quota) when used in conjunction with Delete archive after processing. When using this feature we suggest having 10Mb plus the size of your part for split archives free in your account. The drawback with enabling this option is that if the upload fails, the backup fails. If you don't enable this option, the upload process will take place after the backup is complete and finalized. This ensures that if the upload process fails a valid backup will still be stored on your server. The drawback is that it requires more available disk space.

When this option is set to No (default) the backup will not stop if uploading the backup archive to the remote storage fails. A warning will be issued, but the backup will be marked as successful. You can then go to the Manage Backups page and retry uploading the backup archive to remote storage. This is useful if the backup failed to upload because of a transient network or remote server issue, or a misconfiguration you have fixed after the backup was taken. This also acts as a safety net: if your site breaks after the backup is taken you can restore from the latest backup archive which failed to upload —in whole or in part— to remote storage.

When this option is set to Yes the backup will stop as soon as Akeeba Backup detects that it failed to upload a backup archive to the remote storage. If you have set Process each part immediately to No (default) that will be it; the backup attempt will be marked as Failed and all backup archive files of this backup attempt will be removed. If you have set have set Process each part immediately to Yes and some backup archive files have already been uploaded to the remote storage they will be left behind when the backup attempt is marked as Failed; you will have to remove them yourself, manually, outside of Akeeba Backup. In either case you will not have a valid backup. If your site breaks before you can rectify the problem you are left without a backup.

Considering that the vast majority of the rare occurrences of backup upload failures we see are transient issues, we consider this option to be dangerous as it can unexpectedly leave you without a valid backup when you need one. It is far better to leave this setting set to No and monitor your backups for warnings. There are extremely few use cases where this option makes sense (e.g. taking a backup of a site on a server without enough space for both the backup archive and the site to coexist, a situation which is anyway problematic should you need to restore the backup). We very strongly recommend not enabling this option unless you have a compelling use case and understand the implications of potentially being left without a valid backup at random.

If enabled, the archive files will be removed from your server after they are uploaded to iDriveSync

Your iDriveSync username or email address

Your iDriveSync password

If you have locked your account with a private key (which means that all your data is stored encrypted in iDriveSync) please enter your Private Key here. If you are not making use of this feature please leave this field blank.

The directory inside your iDriveSync where your files will be stored in. If you want to use subdirectories, you have to use a forward slash, e.g. directory/subdirectory/subsubdirectory.

	Tip
	You can use backup naming variables in the directory name in order to create it dynamically. These are the same variables as what you can use in the archive name, i.e. [DATE], [TIME], [HOST], [RANDOM].

This is required for iDriveSync accounts created after 2014. If you have entered your username/e-mail and password correctly but Akeeba Backup can't connect to iDriveSync please try checking this box.

Lengthier explanation. Sometime after 2014 iDriveSync started signing up new users through iDrive.com instead of iDriveSync.com. The new accounts need to access a new service endpoint (URL) to upload new files, delete existing files and so on. Meanwhile, accounts created before this change still need to access the old service endpoint (URL). The same service, two different interface implementations, making it impossible for us to automatically detect which method will work with your iDriveSync account. Therefore the only thing we could do was add this confusing checkbox. We're sorry about that.

The username you use to connect to your WebDAV server

The password you use to connect to your WebDAV server

The base URL of your WebDAV server's endpoint. It might be a directory such as http://www.example.com/mydav/ or even a script endpoint such as http://www.example.com/webdav.php. If unsure please ask your WebDAV provider for more information.

	Warning
	If the base URL of your WebDAV server's endpoint is a directory (almost always) you MUST use a trailing slash, e.g. http://www.example.com/mydav/ (correct) but not http://www.example.com/mydav (WRONG!)

The directory inside the WebDAV folder where your files will be stored in. If you want to use subdirectories, you have to use a forward slash, e.g. /directory/subdirectory/subsubdirectory. You may use the backup naming variables, e.g. [HOST] for the site's host name or [DATE] for the current date.

	Warning
	You MUST always use a directory. Most WebDAV servers, e.g. Box.com, allow you to use the root directory which is denoted by / (a single forward slash). Other WebDAV servers, such as CloudDAV, DO NOT allow you to use the root directory. In this case you MUST use a non-empty directory, e.g. /backups for the upload to WebDAV to work at all.
