Have you looked into VMWare's Data Protection which is offered for free?
Yeah... and I dismissed it based on the outright lies that make up the ad copy:
"Traditional data backup and data recovery solutions are expensive, slow and complex."
Fallacy 1: Expensive. No, they're not. A 16-slot rack-mount library costs around $4K. Most of that is the drive itself; the loader mechanism is cheap. LTO-6 cartridge prices have dropped to about $50 each in bulk. That times 16 is $800 for each ~100TB of storage capacity.
Fallacy 2: Slow. No. "Slow" isn't an absolute; it's relative to something else. Certainly, magtape is slower than most rotating platter media but that's irrelevant. It's part of a backup system. It doesn't need to be the fastest thing going. It needs to be reliable and the backup history depth needs to be scalable.
Fallacy 3: Complex. This is all about horizontal scale. TSM is a complex system but it needs to be in order to handle literally thousands of simultaneous backup clients. A simple tape deck attached to a small database server is no more complex than the shell script that freezes the database, dumps it to disk, thaws the database, and writes the dump to tape.
