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


Change owner of the directory to resolve the problem.
