You are consulting with a large multinational bank about its backup and recovery environment.
The customer has concerns about backup performance, ease of administration, and offsite
regulatory compliance. The customer has asked for a solution to improve overall backup,
recovery, and disaster recovery performance.
The solution must require the fewest changes possible in the bank’s current processes (people
and technology). In addition, the solution must ensure that backup clones are sent to the offsite
location as soon as the backup completes.
Which solution best satisfies the bank’s requirements?

A.
Implement a physical tape library and an EDL. Perform the backups to the EDL and then clone
the tapes to the physical library. Remove the tapes from the library, sending them over to the
offsite location.

B.
Implement a physical tape library in the primary site and an EDL solution in the remote site.
Perform the backups to the onsite tape library and then clone the tapes over the WAN to the
remote EDL(s).

C.
Implement aCLARiiON solution at each site. Do the backups to the onsite CLARiiON and then
clone the datasets over the WAN to the remote CLARiiON with SAN Copy.

D.
Implement an EDL solution. Do the backups to the onsite EDL within the backup window and
then clone the tapes over the WAN to the remote EDL.
