While reading many of the blogs and posts here about self hosting, I notice that self hosters spend a lot of time searching for and migrating between VPS or backup hosting. Being a cheapskate, I have a raspberry pi with a large disk attached and leave it at a relative’s house. I’ll rsync my backup drive to it nightly. The problem is when something happens, I have to walk them through a reboot or do troubleshooting over the phone or worse, wait until a holiday when we all meet.
What would a solution look like for a bunch of random tech nerds who happen to live near each other to cross host each other’s offsite backups? How would you secure it, support it or make it resilient to bad actors? Do you think it could work? What are the drawbacks?
I’ve done a backup swap with friends a couple times. Security wasn’t much of a worry since we connected to each other’s boxes over ssh or wireguard or similar and used tools that allowed encryption. The biggest challenge for us was that in my selfhosting friend group we all prefer different protocols so we had to figure out what each of us wanted to use to connect and access filesystems and set that up. The second challenge was ensuring uptime and that the remote access we set up for each other stayed up - and that’s what killed the project as we all eventually stopped maintaining the remote access and nobody seemed to care - so if I were to do it again I would make sure all participants have alerts monitoring their shared endpoint.
This reminds me that I need alerts monitoring set up. ; -)
Trunas with Tailscale/headscale/NetBird as far as software and security. As far as hardware, you want storage that is not attached via usb. Either an off the shelf nas solution or a diy nas would work. There are a few YouTubers that touched on this, hardware haven and raidowl I think.
I have tailscale mostly set up. What’s the issue with USB drives? I’ve got a raspberry pi on the other end with a RO SD card so it won’t go bad.
Reliability of connection to the drives, especially during unscheduled power cycles. USB is known for random drops, or not picking the drive up before all your other services have started, and can cause the need for extra troubleshooting. Can run fine… or it could not. This is in reference to storage drives, not OS drives.
It sucked when Crashplan’s home client went under. If you installed the client on two computers with internet access, it would let you set the remote computer as a target. Encryption was done at the source, it had dedupe, versioning. It ate a little ram but it was really nice.
