Zrepl is a big part of why I feel secure doing the digital nomad thing. A script, run nightlyish, opens a separate-headered LUKS-protected ZFS pool and then copies all snapshots over. That NVME enclosure lives in my "purse" that never leaves me sight/body.

Between this and NixOS, I can provision a new identical laptop in about 10 minutes.

I recently added off-site replication as well, so even if I get completely devastatingly mugged, there's still about zero chance of serious data loss.

Zrepl is absolutely brilliant software. Easy to run with, but incredibly sophisticated and powerful if you need all the knobs. I can't praise it enough.
