The Risk Of A Disk-Only Backup Strategy

With the dramatic reduction in the price of hard disk drives (HDD) over the years, many IT professionals are implementing disk-to-disk backup strategies to safeguard their data, and some have begun to question whether tape backup has a place in the enterprise at all. This paper considers the risk of a disk-only strategy in light of recent research into HDD reliability in real world environments, and reveals the results of a Tape Cartridge and Disk Drive Handling Test performed by Percept Technology Labs that clearly illustrates the vulnerability of disk and the superiority of tape for disaster recovery and archiving.
