Make sure to copy any corrupt files before starting recovery. The files may be instrumental in recovering data later. If you need to recover files from corrupt document management storage without having a backup available contact firstname.lastname@example.org for assistance or access to tools for doing this.
If you are using scheduled backup tasks, you can recover from them with the Server Administrator client. Select the database you want to recover and take it offline by pressing Online/Offline state. When the database is offline, press Restore. You can either provide the path manually to the backup directory or select a backup from the "Found backups" drop-down.
You can select what you want to restore from the backup. If you only restore the project database the current document management storage will be left in its current state. This can be important because you may only want to restore the project database to recover from an accidental deletion or change.
