A manufacturing customer has decided to consolidate storage onto a CLARiiON. The customer uses a mix of Windows and UNIX workstations during the product design process. One of the customer’s goals is to use pointintime copies of data to make backups easier. In addition, they would like to have the ability to use the pointintime copies to perform a fast recovery in the event of accidental file deletion. The cost of the solution is important.
Your survey of the environment shows that the read/write ratio of the application is 3:1. The application appears to be insensitive to disk response times.
Based on the information you have gathered, which solution should you recommend?

A.
Take snapshots of the LUNs to be backed up.
Clone each LUN for fast recovery of files.

B.
Take snapshots of the LUNs to be backed up.
Clone each LUN for protection against accidental file deletion.
Synchronize and fracture the clones every hour.

C.
Take snapshots of the LUNs to be backed up.
Keep the sessions running for protection against accidental file deletion.

D.
Use clones on the LUNs to be backed up.
Take snapshots of the clones for protection against accidental file deletion.
