The following error is generated when try backuping a domain through Plesk -> Domains -> DOMAIN.TLD -> Back up -> Backup Now:

Error: Unable to create backup session: Specified file is not accessible

Cause

Temporary backup directory /var/lib/psa/dumps/tmp has incorrect owner.

Resolution

The directory must be owned by psaadm:psaadm

~# ls -ld /var/lib/psa/dumps/tmp
drwx------ 2212 psaadm psaadm 80896 Aug 21 12:54 /var/lib/psa/dumps/tmp
~#

Change owner of the directory to resolve the problem.

~# chown psaadm:psaadm /var/lib/psa/dumps/tmp
