A customer has decided to consolidate storage onto a CLARiiON. There is a mix of Windows and
UNIX workstations in the environment. One goal is to use point-in-time copies of data to make
backups easier. A secondary goal is to use the point-in-time copies to perform a fast recovery in
the event of data corruption.
Your initial survey of their environment shows that the read/write ratio of their application is 1:1.
The application appears to be sensitive to disk response times, especially when updating

engineering design documents.
Which initial solution should you consider?

A.
Back up the LUNs from clones. Take periodic snapshots of the clones for protection from
corruption.

B.
Back up the LUNs from snapshots. Clone each LUN for protection from corruption.

C.
Take snapshots of the LUNs to be backed up. Take additional hourly snapshots of each LUN
for protection from corruption.

D.
Take snapshots of the LUNs to be backed up. Take additional snapshots of each LUN for
protection from corruption.
