A national bank is using EMC DiskXtender for Windows to archive scanned check images to an EMC Centera and inactive file data to tape media. Check images are being migrated to the EMC Centera using realtime moves. EMC DiskXtender is configured to purge files immediately after a move.
The bank is using EMC NetWorker to back up the EMC DiskXtender server and creating remote copies of the tape media. The bank is now analyzing their archive environment to prepare for disaster recovery and is not interested in adding any new infrastructure.
Based on the bank’s environment, which solution should you suggest to achieve a comprehensive disaster recovery plan?

A.
Archive the check images to multiple virtual pools on the EMC Centera

B.
Back up the EMC Centera using CBRM

C.
Enable collision avoidance on the EMC Centera and replicate the EMC Centera to itself

D.
Simultaneously archive the scanned check images to tape
