ADR 0214 / to-be 43. restic keeps one repository per machine and takes a nightly snapshot per module — 14 daily, 8 weekly, 6 monthly — and restores beside the live data, never over it. postgres, mssql and mongodb contribute a consistent dump; minio, influxdb, the vault, mailu, gitea and nextcloud the directories that hold their data.
