• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.
  • (Plesk for Windows):
    MySQL Connector/ODBC 3.51, 5.1, and 5.3 are no longer shipped with Plesk because they have reached end of life. MariaDB Connector/ODBC 64-bit 3.2.4 is now used instead.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.

Question "Unable to upload dump to FTP, it remains in server repository", Oh no it doesn't!

R

Richard18

Basic Pleskian
Ubuntu 14.04.5 LTS‬
Plesk version 12.5.30 Update #57

Over the last few days we've had a few backups fail on the upload to our external FTP server with timeout issues.

The backup log says: Unable to upload dump to FTP, it remains in server repository and you can manually download and upload it to FTP.

But, I can't find the backup on the server to manually upload to the FTP server, it looks like the backup process fails and then it deletes the backup tars. I can see from the file system usage graphs that after the backup fails, the fs usage goes back to what it was before the backup.

/var/lib/psa/dumps just has a domains folder with some compressed sql files and some mysql.daily.dump files.

There are none of my backup_XXX.tarX files, how do I get the server to keep the .tar files if the backup fails so I can manually transfer them if need be?

PS, maybe the backup logic could be changed so that if it fails to upload a tar and can't resume the file, it actually tries to upload the whole file again and again (within reason), until it completes the backup operation and not just fail?

Code: 
INFO: Ftp init url ftps://xxx/backup_1701240206.tar9
INFO: Error 28 Timeout was reached
INFO: Trying to resume upload...
INFO: Unable to resume interrupted upload. It seems like FTP server deleted the file, when the connection was lost. Try to repeat or perform upload manually
 
Make sure that it is not issues on the FTP server's side:
  1. Not enough free disk space on the FTP server.
  2. No permissions for the FTP user to write to the target directory.
 
Over 100GB free on the server, backup size is ~28GB, split into 512MB chunks and the FTP user can definitely write to the target directory.

I'm sure it's just a transient issue with the destination FTP server, but I'd still like to be able to manually upload the tar files to it when a backup fails, like the log file says I can do?

Code: 
INFO: Ftp init url ftps://xxx/backup_1701240206.tar
INFO: Ftp init url ftps://xxx/backup_1701240206.tar1

Any additional details from /usr/local/psa/PMM/logs/backup-<datetime> log file?
 
This is the end of the file where it starts to go wrong, slightly edited to remove server/user names.

Try to debug it with command like

# /usr/local/psa/admin/sbin/pmm-ras --check-repository --debug --verbose --dump-storage=ftp://login@<ftp.server.name>/<dumpstoragepath>
 
I can't get that to work, it doesn't ask me for a password when I run the command and if I try and put the password in the line it still fails to log in. I can log in fine with the FTP details I'm using!

ie: /usr/local/psa/admin/sbin/pmm-ras --check-repository --debug --verbose --dump-storage=ftp://USERNAME:pASSWORD@FTPHOST
