Note that it also supports remote sync, and that backups can be
encrypted by the client, this opens a few possibilities.

One could be having local "hyper-converged" backup servers in each small
cluster, and one central (or depending on safety concerns, two) big server to
have a off-site copy of all the data in the case a cluster one fails. As data
can be encrypted by the client the backup server doesn't have to be fully
trusted. And as remote sync schedules are done efficiently (only the delta) one
could have a remote over the WAN.

This won't be the primary recommended setup, as a big (enough) local server as
primary backup is always faster and better than a hyper-converged one, but
should work for situations where one is limited by local available HW.
