Without the data, there is no recovery. If you have to pick one element of a recovery, start with your data. Backing up critical systems and protecting these backup tapes off-site provides a foundation that can not be acquired after a disaster has struck. Current, reliable backups are essential to any disaster recovery effort. Off-site backups provide more than just data protection, they provide business protection, because without them a company may be out of business. Is one method or technique of backing up data better than another? It depends on how much your business relies on your computer applications and how quickly you need to have them restored if there is a problem.
