First let me clarify your confusion.

According to the log file, the backup is successful. Your database and files have been backed up and the archive file has been finalized. This is what makes a backup successful.

Keep in in mind that transfer to remote storage is NOT a criterion for considering the backup successful. A successful backup is one which you can use to restore your site if someone deleted its files.

Now, let's see what you actually need help with.

Your log file is at the wrong detail level (information only) so I can't tell if the upload to remote storage has been completed. Based on what you told me, it hasn't. If it had then the backup would appear as Remote (blue) instead of OK (green). Remember what is the difference between them: green = the backup archive (or at least some of its parts) is still on your server whereas blue = all the backup archive parts have been transferred to remote storage.

So I guess the actual issue you need help with is "Upload to <insert your remote storage type here> fails". We can help you with that, but we do need a log file taken with the log level set to "All Information and Debug". This will tell us what is going on during the upload to remote storage step which you are actually interested in, including which remote storage type you are using :)

In case the massive signature below my reply wasn't very clear, I am the LEAD DEVELOPER of Akeeba Backup. I wrote the software all by myself in 2006 when it was still called JoomlaPack. Just Google my name. I know what I am talking about. Not only have I written Akeeba Backup, I have also written a big chunk of Joomla! itself.

Here's what is going on. You have a multipart backup archive. It is created just fine. Then it starts uploading to SOMEWHERE. That fails for SOME REASON after SOME PARTS have been uploaded. The remaining parts remain on your server. So you have X parts on your server and Y parts on the remote storage. This means that the backup status is OK (Green) instead of Remote (Blue) which you'd have known if you read the documentation or my previous reply. If parts of the backup remain on the server the reported size is only these parts. That's why you see 8Mb. The other 130 have already been uploaded to the remote storage.

I had asked you for the log file so that I could see WHERE the backup is being uploaded to, HOW MANY parts are uploaded and infer the REASON why the rest failed to upload. Unfortunately, instead of providing me with the information I asked you insist, wrongly, that it's a bug (it's not) and gave me some attitude. Well, too bad. I could have helped you. Now all I can do is close the ticket with the affirmation that nope, it's not a bug, it's something between your site's server and the remote storage server.

If you want to receive help about the actual issue you have please do file a new ticket and do provide a complete log file as I instructed you in my previous reply. One of the other support staff will help you. For your info, we don't hire cheap outsourced labor here. You only receive support by the developers of the software and one very experienced person who consults with us on technical issues.
