learn.halkyon.eu dumps its database every hour (people's files are in it too) and restic stores the dump encrypted in a Hetzner Storage Box, keeping 24 hourly, 7 daily, 4 weekly and 3 monthly snapshots. The box's own snapshots, removable only in Hetzner's Console, protect the backups from a taken-over server. A systemd timer runs it as deploy; once a day it also prunes and checks the repository. Failures go to the journal. Hourly, because a restore costs people who started after the backup what their device held: the app no longer finds its session and starts anew. deploy/backups.md describes the setup, the restore and what a restore loses; both were rehearsed on the local Compose stack.
