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
bothfile 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
