Manage Headscale backups, restores, or migrations with a verified SQLite.
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
# headscale-backup ## Overview Headscale state is stored in SQLite (its database), `config.yaml`, `policy.json`, and TLS certificates. Regular backups are critical before upgrades, as database corruption or misconfiguration can result in complete loss of node registration and routing state. This skill provides three scripts covering the full lifecycle: backup, restore, and migration. Before creating an archive or restoring files, confirm the target, scope, and rollback path. Read-only discovery and `--dry-run` previews may proceed without confirmation. ## Backup Contents A complete backup tarball includes: - **SQLite DB** — Full node state, users, routes, pre-auth keys, API keys - **`config.yaml`** — Headscale server configuration - **`policy.json`** — ACL policy file (if present) - **Certs and keys** — TLS certificate and key, Headscale node private key, and configured DERP server private key - **DERP map** — DERP configuration file (if customized) ## Backup Methods - **`sqlite3 .backup`** (recommended) — Safe for live databases; uses SQLite online backup API. This is what `hs-backup.sh` uses. …

How to install
mdr add magnus919/agent-skills/headscale-backup@sha256:55dbb046cb1ad707The line at the top of this page pins the label git:20261006.3731b87, 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.
