I've got backup on the brain. I guess this isn't an unusual occurrence for me, but it's also been bolstered by a week at Symantec Vision, a week at EMC World, as well as backup announcements about IBM's data protection hardware and CommVault's PC backup enhancements not to mention the flurry of cloud backup news this week from Trend Micro, CA Technologies, and Carbonite. All of this has gotten me thinking about the future of backup... we've come a long way from simple agent-based backup and recovery. Backup is just one piece in an ever-increasingly complicated puzzle we call continuity. If backup software vendors want to stay relevant they're going to need to offer a lot more than just backup in their "data protection" suites.
