A customer has a current EMC NetWorker LAN backup environment. The environment is using a
local EMC Disk Library (EDL) with replication to a remote disaster recovery site. They want to
introduce a four Data Mover Celerra into their environment for consolidated Windows user
collaborative data on CIFS shares.
Which backup deployment would you suggest that has the least disruptive hardware impact to the
customer’s current backup procedure?

A.
Implement a dedicated network link between two primary Data Movers on the Celerra and use
NDMP three-way backup to back up to directly attached tape devices

B.
Utilize the Celerra NDMP2D feature on a second primary Data Mover and use NDMP-to-Disk
backup to save the first primary Data Mover data to internally configured virtual tapes

C.
Implement a segmented dedicated backup network infrastructure and LAN backup the Celerra
data to their existing backup servers

D.
Directly attach an EDL, through Fibre Channel, to the production Data Mover and use NDMP to
back up the production Data Mover data to the EDL
