"(Near) zero-cost snapshots and filesystem-based incremental backups are amazing." This. We[1] offer ZFS filesystems in the cloud[2] and one of the nicest things to explain to customers is that they don't have to think about "incrementals" or "versions" or retention in any way. They can just do a "dumb rsync" to us (mirror) and our ZFS snapshots, on their schedule, will do the rest. In the event of a restore, the customer just browses right into "5 days ago"[3] and sees their entire offsite filesystem as it existed 5 days ago.
