Symptoms
- A backup fails on a Plesk server due to a full disk, and its leftovers are not removed automatically.
Cause
Bug PPPM-14626, whose resolution is expected to be published in the next few Plesk updates.
Resolution
The workaround for now is to manually remove files from the backup folder (default location is /var/lib/psa/dumps).
Alternatively, the instructions below will also help in finding big files to be removed from the server.
