Any way to get Time Machine to backup to Amazon Simple Storage Solution? Just curious if it is at all possible to have Time Machine backup to the 'cloud' using Amazon Simple Storage Solution. I've setup Time Machine to work over the network before to unsupported volumes (NTFS) but wasn't sure if this is possible. Anyone ever tried?
Dolly Drive is newly-announced software that lets you do TimeMachine backups to "cloud storage". Their docs say the space is their own cloud-based storage space, not S3, so that might be sticking point. But other than that it's pretty much in line with what you're after.

In addition to doing the TimeMachine -> cloud bridge, they also help you duplicate your data to a local drive so you can do fast restores without having to wait for delivery of an cloud -> hard drive dump of your data.

Looks promising. I'm lukewarm on the pricing.
