A deduplication storage folder is stored on the Backup Exec media server. If your media server experiences a disaster, then the data from the deduplication storage folder is lost. Therefore, you should take steps to prepare for recovery from a system failure. To prepare for a disaster, Backup Exec lets you take a snapshot of a deduplication storage folder. The snapshot includes the folder, the contents of the folder, and the associated database for the folder. You can store the snapshot on tape, which you can then use to recover your deduplication storage folder after a disaster.
When you restore data from the snapshot, the following processes occur:
Backup Exec stops the deduplication services if they are running. The deduplication services are separate from the Backup Exec services, so the Backup Exec services are not affected.
Backup Exec deletes any files that are present in the deduplication storage folder and in the associated database.
The deduplication storage folder is restored to its original location, along with the contents of the folder and the associated database.
