All enterprise businesses backup their data but how confident are they that they can restore it? As more companies adopt disk as their primary target for backup, they can be lulled into a false sense of security thinking that their issues associated with recovery are gone. Nothing could be further from the truth. In fact, what some companies are finding out is that while their immediate backup problems are solved, their issues surrounding recovery are just beginning. Tape typically remains part of many companies' backup processes so the movement and recovery of data from tape media cannot be ignored and even recovering backup data from disk after it is copied to another disk system is not without its challenges.

A specific problem that companies need to keep in mind is how do they recover data after it is no longer kept only on the disk subsystem on which it was initially stored? Backup data can be moved from disk to tape or other disk systems by a variety of methods. The backup software may copy the backup data from disk to tape. The disk subsystem may replicate the backup job to another disk subsystem at another site. There are even some disk subsystems that can copy backup data to disk or tape. This all means that there are a lot of ways for backup data to get lost or misplaced after the backup to disk is complete.
