DS-System Help : Managing the DS-System : Backing up the DS-System database
 
Backing up the DS-System database
By default, the Windows DS-System performs a full database backup to the primary storage location once a day at midnight and appends a differential dump to that database backup file every hour thereafter.
We recommend you perform daily backups of the DS-System database and online storage data to an off-site location. If you have two or more DS-Systems, you can configure them for replication. For more information, see “DS-System Replication”.
IMPORTANT:  You must not schedule additional Microsoft SQL Server maintenance jobs on the Microsoft SQL Server database, because the differential dumps depend on each previous differential backup.
