They are packed, so that's a problem. Every change triggers a repack. Diffs could be daily changes and a device could download a weekly snap, then additional diffs as days progress.

Incremental and differential backup systems are available, but none are as error resistant as a big, huge tarball.

Ideally, one would say GET and the last update timestamp and the server would give you what's new. That, however, would require for a server to repack each response, dramatically reducing capacity of a server, in the order of two zeroes, maybe more.

Besides, any changes in this system would require massive updates to all devices, breaking older versions, etc.
