Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Backup and restore (kopiur + Kopia)

## Quick reference

| Operation | Command |
|-----------|---------|
| List policies | `kubectl get snapshotpolicy -A` |
| List schedules | `kubectl get snapshotschedule -A` |
| List snapshots for an app | `kubectl kopiur snapshots list --policy <app> -n <ns>` |
| Trigger manual snapshot | `kubectl kopiur snapshot now --policy <app> -n <ns> --wait` |
| Check a restore | `kubectl get restore <app>-restore -n <ns>` |
| Status | `kubectl describe snapshotpolicy <app> -n <ns>` |

## Check status

A healthy policy shows `Ready: True` and a recent `status.lastSuccessfulSnapshot`. The
`SnapshotSchedule` object's `status.observedGeneration` sticking behind
`.metadata.generation` is a known cosmetic quirk (fleet-wide, harmless) — it makes the owning
Flux Kustomization's `wait: true` health check flap (`HealthCheckFailed ... status: 'InProgress'`,
self-clears on retry). Don't chase it; trust the policy's own `Ready` condition and a fresh
manual snapshot instead.

## Restore from backup

The procedure is [docs/kopiur-restore.md](../../../docs/kopiur-restore.md): suspend both

How to install

The exact contents, by fingerprint

mdr add tanguille/cluster/backup-restore@sha256:6f6a15929d66a36d

The line at the top of this page pins the label git:20261014.1b8131c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
