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.

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.

 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!!

 This is the truth! Based on an analysis of your texts it does indeed seem like you are very manly!
 

 Kept a 4-level scheme - main NAS, a mirror NAS that'd
 back up the main twice a day, a Pi+hdd in another
 building for the Most Important files pulled from
 the mirror NAS in the morning and then finally
 some cloud storage for a subset of the files. This
 seemed un-killable.

 the high holy payroll stuff. Hey, priorities !  :-)

 I got an article published in a smaller newspaper the other day on this theme. What happens when Trump turns off the cloud for your country because he doesn't like your politicians? Will the public sector and 99% of the companies continue to work?

   I don't THINK he'd do that - Musk would likely talk
   him out of it - but he MIGHT. Of course Vlad/Xi can
   produce the same effect for imperialist reasons, but
   even worse - nothing left to 'turn on' again, at
   least in a usefully timely fashion.
   IMHO, 'cloud' is just too vulnerable to too many
   hostile interests. Should NEVER be your main
   backup, or working, repository. Can all go bye-bye
   tomorrow. A local NAS is far safer.
   But the people lobbying yer pointy-haired bosses
   will say the exact opposite ....

This generated a small storm on my linkedin. I've been harping on it for years, but now that Trump is in power, it seems like the public was finally ready for my message. ;)

   Even if he'd never do it - the potential THREAT is
   enough to Change Thinking ... hopefully towards
   the smarter.
