I do something like this! I’m based in NY but my dad’s in LA. I put together an rpi5 + 5xSATA hat with 3 10TB WD red drives using zraid1 (managed to pick these up over the holidays before prices started going up, $160 per drive!). 3D printed the case and got it running a diskless alpine image with tailscale and zrepl for ZFS snapshot replication. Just left it running in a corner at his place and told him not to touch it heh
Whole thing cost around $500. Before that I was paying ~$35 a month for a Google workspace with 5TB of drive space. At one point in the past it was “unlimited” space for $15 a month. Figure the whole thing will pay for itself in the next couple of years.
Actually just finished the initial replication of my 10TB pool. I ran into a gnarly situation where zrepl blew away the initial snapshot on the source pool just after it finished syncing, and I ended up having to patch in a new fake “matching” snapshot. I had claude write up a post here, if you’ll excuse the completely AI generated “blog post”, it came up with a pretty good solution https://gist.github.com/evanpurkhiser/7663b7cabf82e6483d2d29...
