Many enterprises have been insourcing IT disaster recovery (DR) in recent years through a combination of disk-based backup, server virtualization and, increasingly, cloud server capacity. DR providers are now doing many of the same things, changing the nature of what CIOs can and should expect from outsourcing DR.
One clear example is the shift from tape to disk backup. DR providers have long made a living picking up and storing tapes. Now, almost all the vendors interviewed for our DR trends story said they were advising clients to move from tape to electronic vaulting for backup, both to save money and improve recovery service levels.
