For a large business, this looks like a great product. Way too expensive for an individual or very small company. Jungle Disk is a lot cheaper, and I am going to set my wife's MacBook up to use it since she is not so good about backing up frequently to Time Machine. Personally, I use a remote git server, and frequently back up the remote git directories to S3. The only problem is this is not secure if remote servers get hacked so there is quite a bit of proprietary work (mostly for customers) that only gets backed up by zip/gnupg copied manually to S3. I would like to use some form of encrypted git but that is not (I am fairly sure) practical.
