If you're intrigued by using basic unix primitives for tasks like this you'd probably also be intrigued by a cloud storage product that was built to act like a unix primitive.[1][2]
If you're interested in point-in-time snapshots, you're probably also intrigued by our ZFS platform that gives you day/week/month/quarter/year snapshots that you don't have to configure or maintain - you just do a "dumb" rsync (or whatever) to us and the snapshots just appear.
If you're interested in encrypted backups you should look into the 'borg backup' tool which has become the de facto standard for remote, encrypted, changes-only-upload backups.[3][4]
Finally, if S3 pricing is important, you should email us about our "HN Readers'" discount.
