Off-host backups for every self-hoster, configured entirely in the admin UI — supersedes the host-specific mirror plan behind #84. shared: - webdav.ts (new package entry like token-crypto): minimal WebDAV client with basic auth — PROPFIND (tolerant multistatus parser), MKCOL, PUT (streamed), GET, DELETE; Nextcloud DAV path derived from the plain server URL, explicit DAV bases pass through - backup-status.ts: additive remote-upload status in status.json, the restore-status.json contract (running/succeeded/failed + staleness bound), the backup_command/backup_maintenance NOTIFY channels, and the one-bundle-per-set naming (dorfteich-backup-<id>.tar.gz) - backup-set.ts moved here from apps/backup (api lists local sets) backup sidecar: - reads the backup.* instance settings directly from the database (admin changes apply next run; local retention row overrides the env) and the app password from the secret store - after each successful set: bundle dump + files archive + manifest into ONE self-contained tar.gz, upload via WebDAV per schedule (off/daily/weekly; manual runs always upload), prune remote bundles — never the newest — and record the outcome in status.json; upload failures alert via a new backupUploadFailed mail (de+en) - command listener on backup_command (run / restore) with a serial queue against the nightly timer - restore orchestrator: restore-status.json → maintenance NOTIFY → grace → (remote: download + manifest-verify bundle) → terminate other DB connections → shared perform-restore path (same code as restore.sh) → final status + maintenance exit api: - MaintenanceGuard (global, registered before the setup gate): 503 maintenance_mode while restore-status says running; health endpoints and the new public GET /backup/restore-status stay exempt; a stale running state (crashed sidecar) unblocks after 30 min - MaintenanceStateService watches the file and restarts the api after a successful restore (fresh caches, migrate-on-start for older dumps); main.ts refuses to touch the database while a restore runs — a container restarting mid-restore must not race pg_restore with migrate deploy - worker sweeps (conversion, mail outbox, scheduler) catch transient database failures instead of dying on an unhandled rejection — the restore's connection termination crashed the api in verification - backup admin endpoints under /admin/system/backup: settings (live connection test before save, password write-only into the secret store), nextcloud/test, sets (local via the ro backups mount + remote via WebDAV), run + restore (type-to-confirm backstop, source validation) — commands travel as NOTIFY payloads; audit actions backup.settings_changed/run_triggered/restore_requested - readyz: new warning-level backup_remote check while a target is configured (26 h daily / 170 h weekly bound) collab: - maintenance listener: on enter, persist + close every live session and refuse new connections until exit (failsafe timeout 30 min) — no in-memory document may write pre-restore content back afterwards web: - Admin → System backup section: status card with remote facts and a "Back up now" button, the Nextcloud settings form with test button, and the restore picker (local + remote sets, type-to-confirm) - global maintenance screen: any 503 maintenance_mode flips the SPA to a status page polling the exempt endpoint, reloading when the instance returns Verified end-to-end against a live stack (fresh DB, native api + sidecar, fake WebDAV server): configure → test → manual backup → bundle upload → readyz/sets/status surfaces → remote restore with maintenance gate, marker rollback and api restart; suites: shared 21, backup 9, collab 11, api 58 files green, lint + i18n:check + typecheck clean.

Add backup sidecar: nightly dump, volume archive, prune, status, restore (#83)

New apps/backup service (ADR 0015): nightly pg_dump -Fc plus one tar of the uploads/plugins volumes as a consistent restore set on a new backups volume, retention prune that never removes the newest complete set, atomic status.json for the readiness/admin consumers (#85/#86), and a failure mail sent directly via nodemailer (the api may be the broken part) with de/en texts in the shared mails catalog. BACKUP_RUN_ONCE=1 gives the on-demand path; deploy/backup/restore.sh automates the documented restore runbook. The pure secret-store helpers moved to @dorfteich/shared so the sidecar resolves the wizard-written SMTP relay exactly like the api.
