Unable to create a backup on a remote storage: Not enough free disk space to backup selected objects

Symptoms

• Plesk is unable to create a backup in Tools & Settings > Backup Manager using remote storage

• This error is displayed when trying to do a backup on a remote storage:

  PLESK_ERROR: Not enough free disk space to backup selected objects. At least 231208.573798 Mbytes free disk space is required.

• The checkbox Start the backup only if your server has the sufficient amount of free disk space (this option may significantly increase the backup time) is checked in Tools & Settings > Backup Manager > Backup Settings

Cause

Insufficient disk space on the Plesk server.

Resolution

Allocate additional disk space or remove unnecessary files in /var/lib/psa/dumps.

OR

Uncheck the option Start the backup only if your server has the sufficient amount of free disk space (this option may significantly increase the backup time) in Tools & Settings > Backup Manager > Backup Settings to make Backup Manager not count overall disk space required for the backup.
