Backups larger than 2047 MB to FTP don't finish

[Squeeze999]

Backups larger than 2 GB to ftp storage don't come to an end, backup file remains also local and isn't deleted after writing to ftp.
Dividing backups into slices of 2 GB works fine but copying them back to server storage via backup manager fetches only the first file (xyz-12345.tar) not the *.tar.1 *.tar.2 ... files.

Do you have any related error messages in backup logs?

 

[Squeeze999]

No there are no error msg in backups. Last lines of backup.log:

There is one file in FTP repo and the same file in server repo.

Downloading the files from ftp repo to server repo via pmm-ras fail with a time out. Is there any way to change ftp request timeout in Plesk 12.0 for Linux?

 

[Dmitry Y.]

No. there are no special setting for timeout control. If you enable debug in panel.ini backup log will contain FTP connection RAW commands. It may help to find possible problems.
Which version of Plesk do you use?

 

[Squeeze999]

I am using 12.0.18.63
Meanwhile I managed to backup my production system by cutting the backup into 512MB slices.
I still get the timeout msg in the web frontend, but import is finishing with warning.
I'll try to switch on debug mode and upload the trace.
