Backup from Plesk CP fails with the error:

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

If "display_errors" is enabled in /usr/local/psa/admin/conf/httpsd.conf the following warning also appears:

readlink() [function.readlink]: Permission denied in
/usr/local/psa/admin/plib/PMM/MigrationDemon.php on line 134


Make sure that /var/lib/psa/dumps/tmp directory has the "psaadm" owner and group:
# ls -dl  /var/lib/psa/dumps/tmp
drwx------  3 psaadm psaadm 2048 Jun  6 05:23 /var/lib/psa/dumps/tmp

If not, change it with:
chown psaadm:psaadm /var/lib/psa/dumps/tmp
