Description of my issue:

Hi. I've been getting the same message when trying to backup through remote ftp. This used to work fine until a few works ago when it just stopped working. The proved insist nothing has changed on their servers.

I get the message :

Uploading /hsphere/local/home/c299501/adplayer.co.uk/site/safe/site-adplayer.co.uk-20110514-084311.jpa has failed.
Failed to process file /hsphere/local/home/c299501/adplayer.co.uk/site/safe/site-adplayer.co.uk-20110514-084311.jpa
Post-processing interrupted -- no more files will be transferred</pre>




Is there a debug mode or something that will help to get to the bottom of this?



Any ideas will be much appreciated.



Thanks, Harry

I can see that the upload fails about 3 minutes after it has started. This can mean quite a few different things:
1. You are not using Passive mode and firewalls in either the web site server or the remote FTP server (or both) do not allow this kind of file transfer. In this case, please use the Passive mode option.
2. You are running out of disk space on your FTP server. According to the log, the backup is about 15Mb, so you need at least that much free space to transfer the archive.
3. Check that the login credentials to the remote FTP server are correct, including the initial directory. Some FTP hosts will delay the login process for about three minutes when they see invalid login credentials to deter attacks which try to brute-force passwords.

Hi.

1) I checked passive mode and that is set.
2) Also, there is plenty of disk space on the ftp server
3) Credentials are okay as well as I can connect using the same on filezilla, and also when I click on 'test connection' that comes back sucessful.

I took a copy of the website and restored it on my pc at home, and on that the backup backs up fine...

OK, we now know that you can connect to the other server but not transfer any files to it. The only thing I can imagine is some odd firewall / packet filtering configuration on your site's server. FTP connects to the remote host by communicating over port 21 in what is called the "control channel" of the FTP communication. When you ask to transfer a file, it tries to open a "data channel" to funnel the data to the remote end. It looks as if this can not happen and results to a timeout error (it so happens that the default timeout of most FTP servers is 180 seconds, that is 3 minutes). Since you can connect from other computers, the problem doesn't happen on the FTP server's end, it happens on the site server's end. Therefore, the only possible explanation (at least, the only one that I am aware of) is that your host is applying some kind of packet filtering which disallows FTP data transfer from taking place. Can you ask your host to check this out? There's nothing we can do on our end.
