One could be having local "hyper-converged" backup servers in each small cluster, and one central (or depending on safety concerns, two) big serve= r 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 delt= a) one could have a remote over the WAN. This won't be the primary recommended setup, as a big (enough) local serv= er as primary backup is always faster and better than a hyper-converged one, bu= t should work for situations where one is limited by local available HW. cheers, Thomas
