A customer has recently added a Celerra to their environment and has asked you to assess
their current data protection methodology. They currently have an EMC NetWorker
environment using an EMC Disk Library (EDL) as the primary backup location before they
move the virtual tapes to physical tapes. How over, the rate of change of the data on the
Celerra is too high for their RPO using the EDL for single file recovery if their backups are
performed only at the end of the business day. What would you incorporate to lessen the
impact of their once-a-day backup schedule on the Celerra data with minimal impact to their
backup administration processes?

A.
Implement Snap Sure to make point-in-time copies of the file systems more
frequently to recover individual files when requested ad perform full system backups at
the end of the day

B.
Configure a local tape device on the primary Data Mover and use NDMP
incrementally back up the file system more frequently than the once-a-day full backup

C.
Replicate the source data to a remote target using Replicator and use the target
data as both file recovery and backup source

D.
Create an internal SVTLU on the primary Data Mover and use NDMP2D to
incrementally back up the file system more frequently than the once-a-day full backup
