Phase 1: Add 12 PrometheusRules for backup health alerting - PostgreSQL, MySQL, Vault, Vaultwarden, Redis staleness + never-succeeded alerts - CSIDriverCrashLoop alert for nfs-csi/iscsi-csi namespaces - Generic BackupCronJobFailed alert Phase 2: Fix backup rotation - etcd: timestamped snapshots instead of overwriting single file - Redis: timestamped RDB files with 7-day retention purge - PostgreSQL: retention increased from 7 to 14 days Phase 3: Fix MySQL password exposure - Move root password from command line arg to MYSQL_PWD env var via secretKeyRef Phase 5: Add restore runbooks - PostgreSQL, MySQL, Vault, etcd, Vaultwarden, full cluster rebuild

# Restore Vaultwarden
|
|
|
|
## Prerequisites
|
|
- `kubectl` access to the cluster
|
|
- Backup available on NFS at `/mnt/main/vaultwarden-backup/`
|
|
|
|
## Backup Location
|
|
- NFS: `/mnt/main/vaultwarden-backup/YYYY_MM_DD_HH_MM/` (directory per backup)
|
|
- Each backup contains: `db.sqlite3`, `rsa_key.pem`, `rsa_key.pub.pem`, `attachments/`, `sends/`, `config.json`
|
|
- Replicated to Synology NAS (192.168.1.13) via TrueNAS ZFS replication
|
|
- Retention: 30 days
|
|
- Schedule: Daily at 00:00
|
|
|
|
## Backup Contents
|
|
| File | Purpose | Critical? |
|
|
|------|---------|-----------|
|
|
| `db.sqlite3` | All passwords, TOTP seeds, org data | Yes |
|
|
| `rsa_key.pem` / `rsa_key.pub.pem` | JWT signing keys | Yes — without these, all sessions invalidate |
|
|
| `attachments/` | File attachments on vault items | Yes |
|
|
| `sends/` | Bitwarden Send files | No |
|
|
| `config.json` | Server configuration | No — can be recreated |
|
|
|
|
## Restore Procedure
|
|
|
|
### 1. Identify the backup to restore
|
|
```bash
|
|
# List available backups (directories sorted by date)
|
|
kubectl run vw-ls --rm -it --image=alpine \
|
|
--overrides='{"spec":{"volumes":[{"name":"backup","persistentVolumeClaim":{"claimName":"vaultwarden-backup"}}],"containers":[{"name":"vw-ls","image":"alpine","volumeMounts":[{"name":"backup","mountPath":"/backup"}],"command":["ls","-lt","/backup/"]}]}}' \
|
|
-n vaultwarden
|
|
```
|
|
|
|
### 2. Scale down Vaultwarden
|
|
```bash
|
|
kubectl scale deployment vaultwarden -n vaultwarden --replicas=0
|
|
```
|
|
|
|
### 3. Restore the backup
|
|
```bash
|
|
BACKUP_DIR="YYYY_MM_DD_HH_MM" # Set to desired backup
|
|
|
|
kubectl run vw-restore --rm -it --image=alpine \
|
|
--overrides='{"spec":{"volumes":[{"name":"backup","persistentVolumeClaim":{"claimName":"vaultwarden-backup"}},{"name":"data","persistentVolumeClaim":{"claimName":"vaultwarden-data"}}],"containers":[{"name":"vw-restore","image":"alpine","volumeMounts":[{"name":"backup","mountPath":"/backup"},{"name":"data","mountPath":"/data"}],"command":["/bin/sh","-c","cp /backup/'$BACKUP_DIR'/db.sqlite3 /data/db.sqlite3 && cp /backup/'$BACKUP_DIR'/rsa_key.pem /data/ && cp /backup/'$BACKUP_DIR'/rsa_key.pub.pem /data/ && cp -a /backup/'$BACKUP_DIR'/attachments /data/ 2>/dev/null; echo Restore complete"]}]}}' \
|
|
-n vaultwarden
|
|
```
|
|
|
|
### 4. Scale up Vaultwarden
|
|
```bash
|
|
kubectl scale deployment vaultwarden -n vaultwarden --replicas=1
|
|
|
|
# Wait for pod to be ready
|
|
kubectl wait --for=condition=Ready pod -l app=vaultwarden -n vaultwarden --timeout=120s
|
|
```
|
|
|
|
### 5. Verify restoration
|
|
```bash
|
|
# Check pod logs for startup errors
|
|
kubectl logs -n vaultwarden -l app=vaultwarden --tail=20
|
|
|
|
# Test web UI access
|
|
curl -s -o /dev/null -w "%{http_code}" https://vaultwarden.viktorbarzin.me/
|
|
```
|
|
|
|
### 6. Test login
|
|
Log in to the Vaultwarden web UI and verify:
|
|
- [ ] Can log in with your account
|
|
- [ ] Vault items are present and readable
|
|
- [ ] Attachments are accessible
|
|
- [ ] TOTP codes are generating correctly
|
|
|
|
## Estimated Time
|
|
- Restore: ~5 minutes
|
|
- Verification: ~5 minutes
