DS-System Help : Using premium backup and recovery services : DR Drill requests
 
DR Drill requests
DS-Systems licensed from a DS-License Server RLM can allocate DR Drill capacity to specific backups so you can perform a disaster recovery drill.
NOTE:  This option applies only to DS-Systems that are connected to a DS-License Server configured for the Recovery License Model (RLM).
During the scheduled drill period, when a recovery activity is performed on a flagged backup, an additional option appears that allows you to specify if the activity is a DR Drill. The following recovery activities will show the Restore classification option if it is available in the DS-Operator:
Disc/Tape requests when they are written to the buffer. For more information, see “Disc/tape requests”.
Restore of a file generation via the DS-Operator.
Regular restores from the DS-System online storage initiated by the customer through the DS-User display the Restore classification option at the end of the restore wizard. For more information, see the DS-Client User Guide.
