It would be perfect if it could switch automatically between disks (I have a Time Capsule at home and an external HD at work and I hate having to changed the disks manually when I move every day).

Kinda love it. Macbook stopped booting due to some serious file system errors. Diskwarrior wouldn't bring it back to life. Luckily, I had just got my TimeMachine harddrive working again (an OWC Mercury mirrored RAID external drive that might actually be failing itself) and had a recent TM backup. Just in case, I made an image of the current failing volume. After numerous attempts. The only thing that worked was wiping the drive, re-installing an InstaDMG-created image, and using migration assistant w/ the TM harddrive. This restored what I had space to save (Applications, home dir, preferences, etc..) and from the other image (which had everything but was unbootable) I was able to recover my games, music, and other things I kept in /Users/Shared.

My hard drive failed a week ago and I just got my notebook back from a technician. I installed Leopard and when it asked me if I wanted to transfer files I selected "Time Machine backup," plugged in my external hard drive, and 30 minutes later it was like I never left my computer.

Time Machine restored the files, apps, preferences, system preferences, everything. It was seamless.

LOVE IT. Thoughtless backup at it's best. Go out and by a HUGE external drive and don't let this priceless app go to waste.

And the interface is NOT over the top as some say. I ask "who DOESN'T love the idea of time travel"?!?

Ha, only 8 people use it as of now. But yeah... best backup system ever. duh.

oh.... and this isn't exactly freeware, is it?
