Show HN: ZFS+Rsync = Time Machine in the cloud

I'd like to try the service out, but before setting up another account, is there anyone who can compare it with Dropbox? Personally I'd like the 15GB plans (if I don't back up my photos), more than enough for my code, .ai, .pdf and .tex files, but the lack of snapshots (from the front page I understand that I can't go back in time without snapshots) in the cheap plan stops me.

I know that with a local version control repository I can get my files back from the past anyway, but in that case I don't see why I should switch from my free Dropbox account (currently I have 8GB of free storage, and I'm using 1.5 of them).

Any hint would be much appreciated.

Edit: help

This is super cool. Lightweight, off-site Time Machine-style snapshotted backups.

I have been using the beta and it really works well. rsync backup could not be easier than this!

I've been using this for a while now and it's absolutely brilliant.

i first loved StrongSpace for the ability to programatically back things up.

now i love it for the automated snapshots.

who needs carbonite or mozy? this is backup done right for geeks

this is awesome! I really hope this hits the fpage.
