Parallels Plesk Panel Server backup repository
Server backup repository location.
As of Parallels Plesk Panel version 9.0, the structure and location of the server backup repository have both changed.
The root backup directory is now stored in the file /etc/psa/psa.conf, while it is still set by the variable DUMP_D as before:
Backups directory
DUMP_D /var/lib/psa/dumps
Server backups, backups of resellers, clients, domains, and daily MySQL dumps are now stored in this directory.
