You are a designer for ABC.com. While discussing ABC.com’s backup and recovery environment
with them, you discover concerns about backup performance, ease of administration, and offsite
regulatory compliance. ABC.com asks you to design a solution to supply better backup, recovery,
and Disaster Recovery performance. The solution produce only minor changes in ABC.com’s
current processes (people and technology), and it must also make sure that Clones are sent to the
offsite location as soon as the backup completes. Which one of these solutions can satisfy
ABC.com’s needs best?

A.
Implement a real tape library and CDL solution, at least one real tape library onsite and one
CDL at the offsite location. Do the backups to the onsite tapelibrary(ies) within the backup window
and then clone the tapes over the WAN to the remote CDL(s)

B.
Implement aCLARiiON solution, at least one at each site. Do the backups to the onsite
CLARiiON(s) within the backup window and then clone the data sets over the WAN to the remote
CLARiiON(s)

C.
Implement a real tape library and CDL solution, at least one CDL and one real tape library
onsite. Do the backups to the CDL(s) within the backup window and then clone the tapes to the
reallibrary(ies). Remove the tapes from the library, sending then over to the offsite location

D.
Implement a CDL solution, at least one at each site. Do the backups to the onsite CDL(s) within
the backup window and then clone the tapes over the WAN to the remote CDL(s)
