What's a good app for two friends to give each other remote access to a dataset, but then not have local access? (i.e. we store each other's backups)

Hey there!

I've had a FreeNAS box for a decade or more, and my buddy who lives a few states away just got his set up. He wants to not rely on Google for his off-site backup anymore, and I joked, "Hey just send me all your data! I'll give you XX TB of space. And you just allocate the same for me, and it'll be free!"

So... We actually like this arrangement. I use Syncthing all the time, so this comes to mind as the file sync'ing solution, but is there a way so that I would not be able to see his files, even though they're local on my box, and vice versa? Thanks!

It's actually possible with ZFS native encryption + raw replication streams. (The encrypted blocks/records are sent, as is, without the accompanying key to unlock the dataset.)


Keep in mind, you'll still be able to see each others:

• Dataset names
• Snapshot names
• Snapshot creation dates
• ZFS properties
• Total space used by the encrypted dataset/snapshots
