# backup stack
|
|
|
|
Kopia → Backblaze B2. Backs up `/config`, **selected** `labdata` paths (see `SCOPE.md`), and nightly SQL dumps.
|
|
|
|
## Before first deploy
|
|
|
|
1. **Backblaze B2** (recommended offsite — ~$6/TB/mo)
|
|
- Create a bucket (e.g. `valhalla-homelab-backup`)
|
|
- Create an **Application Key** scoped to that bucket
|
|
- Note the S3 endpoint for your region
|
|
|
|
2. **Fill `stack.env`**
|
|
- `KOPIA_REPOSITORY_PASSWORD` — `openssl rand -hex 32`
|
|
- `B2_KEY_ID`, `B2_APPLICATION_KEY`, `B2_BUCKET`, `B2_ENDPOINT`
|
|
|
|
3. **Host paths**
|
|
- `/config/kopia/{config,cache,logs}` — Kopia state
|
|
- `/config/backup/dumps` — nightly SQL dumps
|
|
- `/config/backup/{init-kopia.sh,snapshot-paths.txt,crontab,scripts/}` — copied from this repo (Portainer CE cannot bind-mount relative git paths; sync after editing those files)
|
|
|
|
4. **Register** new Portainer git stack → `stacks/backup` (one-time)
|
|
|
|
5. **Push** → Portainer redeploys within 5 min
|
|
|
|
## After deploy
|
|
|
|
- UI: `http://valhalla:51515` (or add `backup.ginnoir.com` internal-only in Caddy)
|
|
- Subscribe phone to ntfy topic `backup` (or path in `NTFY_URL`)
|
|
- **Restore test** (do once): pick a small dump from `/config/backup/dumps/`, restore to a throwaway container
|
|
|
|
## Schedule
|
|
|
|
| Time | What |
|
|
|------|------|
|
|
| 02:50 | `backup-dump-databases.sh` — SQL dumps |
|
|
| 03:00 | Kopia snapshots (paths in `snapshot-paths.txt`) |
|
|
|
|
## If B2 creds are empty
|
|
|
|
Kopia still starts with UI — configure repository manually, then set policies for each path in `snapshot-paths.txt`.
