ABC.com, who has a mix of Windows and UNIX workstations, decides to consolidate its storage
onto a Symmetrix. ABC.com. ABC.com wants one copy of data for creating backups each night
and another copy to be made during the day. This second copy will be a standby to execute a fast
recovery in the event of data corruption. ABC.com stresses the importance of the solution being
cost effective. Your analysis of ABC.com’s environment shows that the read/write ratio of its
application is 3:1, and that the application appears to be insensitive to disk response times. What
would you recommended solution be?

A.
TimeFinder/Mirror during the day and TimeFinder/Snap during the night

B.
TimeFinder/Mirror for both data copies

C.
TimeFinder/Snaps for both data copies

D.
