Pelsk usually backs up 'horde' database along with 'psa'. You can try to find what's happened there with help of article http://kb.parallels.com/en/9679
Also if you can find it on your source server, backup the existing horde and restore the old one. Use mysqldump to backup and mysql command to restore.
