Restoring a backup that has been created with a prefix like via GUI will result in the following error:

Internal software issue with id #PPPM-2187. It was fixed in Plesk 12.5


Upgrade to Plesk 12.5 by using KB #112166.

If upgrade is not an option please use workaround: use dd-mm-yyyy format when creating a backup.

As for already existing backups with prefix like, they can be restored using pleskrestore utility :

# /usr/local/psa/bin/pleskrestore --restore /var/lib/psa/dumps/21.10.2014_info_1410211423.xml -level server -configuration-only
