Create the same for Restic?

[u1735067]

While Restic has a weak documentation (https://restic.readthedocs.io/en/stable/index.html), which makes very hard to get what the features are at first, or what are the commands it provides, it seems very similar to Borg.

Metadata support, especially for Windows, seems lighter. But without repo lock it seems more reliable to share repo between servers.

Note to self, possible model:

• shared repo for server's system files (more dedup)
• eventually shared repo for logs
• shared repo for content files & stdin sqldumps

But the same principle could be used:

• Server starts rest-server, listen on a port
• Provision client with user, generate Restic passphrase, store it on the client or not (https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html#local for the ENV vars ..)
• SSH to client and trigger backup, data sent back through tunnel

Unix socket maybe possible using -o sftp.command="foobar", but requiring additional socat on both client&server.

Maybe this already exists?
