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 pointintime copies of data to make backups easier. A secondary goal is to use the pointintime 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.
Take snapshots of the LUNs to be backed up.
Clone each LUN for protection from corruption.

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

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

D.
Use clones of the LUNs for backups.
Take periodic snapshots of the clones for protection from corruption.
