Your rsync.net account has ZFS snapshots enabled - at the very least, the smallest default is 7 daily snapshots.
The ZFS snapshots are immutable. Completely. Even root can't write or delete in a snapshot. The snapshot has to be deliberately destroyed with ZFS commands run by root - which of course, the attacker would not have access to.

Ha! Well that simplifies things for me :) Honestly, your service is so solid I can't remember the last time I actually logged in to check something. It really is backup as a utility (you should consider re-branding as "BaaU" lol)

Also, thanks for your business :)
