Backup Strategy
Last updated: 2026-03-21
Overview
The homelab follows a 3-2-1+ backup strategy: 3 copies of data, 2 different storage types, 1 offsite location, plus cloud backup to Backblaze B2.
┌─────────────────────────────────────────────────────────────────────────────┐
│ BACKUP FLOW │
│ │
│ Atlantis (Primary) ──── Hyper Backup (weekly) ──── Calypso (Local copy) │
│ │ │
│ ├── Syncthing (real-time) ──── Setillo (Tucson, offsite) │
│ │ │
│ └── Hyper Backup S3 (weekly) ──── Backblaze B2 (cloud) │
│ │ │
│ Calypso ──── Hyper Backup S3 (daily) ─────┘ │
│ │
│ Guava ──── No backup (risk) │
│ Jellyfish ──── No backup (risk) │

Backup Tasks
Atlantis → Backblaze B2 (Cloud)
| Setting | Value |
|---|---|
| Task name | Backblaze b2 |
| Schedule | Weekly, Sundays 00:00 |
| Destination | s3.us-west-004.backblazeb2.com |
| Bucket | vk-atlantis |
| Encrypted | Yes (client-side) |
| Versioned | Yes (Smart Recycle) |
| Rotation | Keep daily for 3 days, weekly for 4 weeks, then weekly indefinitely |
What's backed up:
/archive— long-term cold storage/documents/msi_uqiyoe— PC sync documents/documents/pc_sync_documents— PC sync documents/downloads— download staging/photo— Synology Photos library/homes/vish/Photos— user photo library- Apps: SynologyPhotos, SynologyDrive, FileStation, HyperBackup, SynoFinder
What's NOT backed up to cloud:
/volume1/media(~60TB) — too large for cloud backup, replicated to Setillo instead/volume1/docker— container data (stateless, can be redeployed from git)
Calypso → Backblaze B2 (Cloud)
| Setting | Value |
|---|---|
| Task name | Backblaze S3 |
| Schedule | Daily, 00:00 |
| Destination | s3.us-west-004.backblazeb2.com |
| Bucket | vk-concord-1 |
| Encrypted | Yes (client-side) |
| Versioned | Yes (Smart Recycle) |
What's backed up:
/docker/authentik— SSO provider data (critical)/docker/gitea— Git hosting data (critical)/docker/headscale— VPN control plane (critical)/docker/immich— Photo management DB/docker/nginx-proxy-manager— old NPM config (historical)/docker/paperlessngx— Document management DB/docker/retro_site— Personal website/docker/seafile— File storage data/data/media/misc— miscellaneous media/data/media/music— music library/data/media/photos— photo library- Apps: Gitea, MariaDB10, CloudSync, Authentik, Immich, Paperless, HyperBackup
Atlantis → Calypso (Local Copy)
| Setting | Value |
|---|---|
| Method | Hyper Backup |
| Schedule | Weekly |
| Destination | Calypso /volume1/backups/ |
| What | Media, photos, documents |
| Encrypted | Yes |
Atlantis/Calypso → Setillo (Offsite)
| Setting | Value |
|---|---|
| Method | Syncthing (real-time replication) |
| Destination | Setillo /volume1/syncthing/ (Tucson, AZ) |
| Distance | ~1,000 miles from primary site |
| What | Docker configs, critical data |
Disabled Tasks
| Task | Host | Reason |
|---|---|---|
| Backblaze S3 Atlantis (ID 12) | Atlantis | Old task, replaced by "Backblaze b2" (ID 20) |
Hosts Without Backup
| Host | Data at Risk | Mitigation |
|---|---|---|
| Guava (TrueNAS) | 3TB personal data, 204GB Jellyfin, 159GB photos, 64GB LLM models | ZFS mirror provides drive-failure protection but no offsite/cloud backup |
| Jellyfish (RPi 5) | 1.8TB photos (LUKS2 encrypted NVMe) | LUKS encryption protects at rest, but no redundancy beyond the single drive |
| Homelab VM | Docker data, monitoring databases | Stateless — all compose files in git, data is regenerable. NetBox/Semaphore DBs are the main risk |
| Concord NUC | Home Assistant config, AdGuard | Container data is relatively small and rebuildable |
Recommendation: Set up Backblaze B2 backup for Guava (personal data, photos) and Jellyfish (photo archive). Both have irreplaceable data.
Recovery Procedures
Full NAS Recovery (Atlantis)
- Replace failed hardware / reinstall DSM
- Restore from Calypso (fastest — local, weekly copy)
- Or restore from Backblaze B2 (slower — download over internet)
- Redeploy Docker stacks from git (all GitOps-managed)
Service Recovery (Any Host)
- All Docker stacks are in git (
hosts/directory) - Portainer GitOps auto-deploys on push
- Just create the Portainer stack pointing to the compose file
- Service-specific data may need restore from backup
Critical Service Priority
| Priority | Service | Backup Source | Recovery Time |
|---|---|---|---|
| 1 | Authentik (SSO) | Calypso B2 daily | ~30 min |
| 2 | Gitea (Git) | Calypso B2 daily | ~30 min |
| 3 | NPM (Reverse Proxy) | Calypso B2 daily / matrix-ubuntu local | ~5 min (redeploy) |
| 4 | Plex (Media) | Atlantis B2 weekly | ~1 hr (metadata only, media on disk) |
| 5 | Paperless (Documents) | Calypso B2 daily | ~30 min |
Monitoring
- DIUN: Monitors container image updates (weekly, ntfy notification)
- Uptime Kuma: Monitors service availability (97 monitors)
- HyperBackup: Sends DSM notification on backup success/failure
