Plesk Backup Manager not working - can't back anything up!

[JamieR]

Hello,

I am using the Plesk Backup PHP script to run a daily full server backup of my server, called via cron. However, for the last few days, it hasn't worked. When I run the backup, I get the following in /usr/local/psa/PMM/sessions/(date)/psadump.log:

MySQL is working fine and isn't running out memory. Max connections is set to 200 but that wouldn't be an issue. Just seems to have stopped working...every site that uses a MySQL db is working fine.

Product version is 11.0.9 and the server is running CentOS 6.5.

Any thoughts would be appreciated.

Thanks,

Jamie

I assume that it might be related to lack of free disk space. Created backup file occupies all free disk space and at this moment mysql stops working.
Have you checked it?
