Good stuff! I replicate between two countries for added resilience. Both rsync and restic work great backing up to a tor hidden service. To speed things up, the first backup can be done locally, and after that, only deltas are sent from around the world.

 That's how we do it.

 It is a powerful way to do it! =)
 

 Often you need just a few files from backup, ones somebody

 With restic you can do it from the client, or, you can mount the backup and
navigate the file tree to get any files you like from the server. I've tried the
server mount and it worked well, without any surprises. You can of course do
full restores as well to a separate folder on the client and move what you like.

 Let me know if you find any weaknesses.
 

 Another way to back up is to 'fork' every file write
 to another, maybe even remote, drive. SoftRAID seems
 to know just what's being written but I've never
 figured out exactly how that works. The idea would
 be to feed the full file path/name of what's just
 been writ/modified into a (de-duplicated) list for
 some daemon or whatever to dupe to yer destination -
 local or cloud. This would be very quick and not bother
 the other gazillion unchanged files.

 At the dawn of time we used to setup replication between storage systems, then
snapshot the replica at various times per day, and for extra security, write out
the snapshots to tape for off site storage. That was backups for real men!!

   Once had tapes, SLOW bastards, but that went by the
