Hyper Backup Configurations (per host)

Atlantis (DS1823xs+)

Current Hyper Backup tasks → bucket vk-atlantis:

/volume1/docker — container data
/volume1/media — media library
/volume1/photos — photo library
/volume1/documents — Paperless-NGX docs
/volume1/archive — long-term archival (includes paperless/ subfolder)
/volume2/ — NVMe volume data

Recommended additions / changes:

✅ Add /volume2/photo/MobileBackup (mobile photo backups)
❌ Remove /downloads if it's still in the task (redundant, large, rebuildable)
Note: Paperless backup is already covered via /volume1/archive/paperless/ (moved from /volume2/backups/ this session)

Calypso (DS723+)

Current Hyper Backup tasks → bucket vk-concord-1:

/volume1/docker (partial — some subfolders excluded)

Recommended additions:

/docker/authentik — SSO data and config
/docker/paperlessngx — document management
/docker/immich — photo library metadata
/docker/nginx-proxy-manager — proxy config and SSL certs
/docker/headscale — Headscale database and keys (critical!)
/docker/actual — personal finance data
/blah/photos_backup_vish — photo backup

Setillo (DS223j) — Tucson, AZ

Current Hyper Backup tasks → bucket vk-setillo:

/volume1/backups — backup destination

Recommended additions:

/homes/Setillo/Documents — Edgar's documents (~114GB, Edgar.tar.gz)
/homes/vish/media — vish media folder

Recommended removals:

/docker — all containers are rebuildable, saves B2 cost

Portainer Backup (vk-portainer)

Automated daily backups of all Portainer stack configurations:

Format: Encrypted .tar.gz archives
Retention: Multiple daily snapshots
Source: Portainer backup API on homelab VM
Destination: vk-portainer bucket

Checking Bucket Status

# Source credentials
source ~/.b2_env

# List all buckets
aws s3 ls --endpoint-url https://s3.us-west-004.backblazeb2.com

# Check bucket contents / recent uploads
aws s3 ls s3://vk-atlantis/ --endpoint-url https://s3.us-west-004.backblazeb2.com --recursive | sort | tail -20

# Check bucket size
aws s3api list-objects-v2 --bucket vk-atlantis \
  --endpoint-url https://s3.us-west-004.backblazeb2.com \
  --query "sum(Contents[].Size)" --output text

Mattermost Backup (vk-mattermost)

This bucket exists but is empty. Mattermost runs on matrix-ubuntu VM on Atlantis. To configure, add a Hyper Backup task from Atlantis targeting:

/volume1/docker/mattermost (config, database dumps)

Or configure a Mattermost-native backup export and push to B2 directly.

Notes

All active buckets use us-west-004 region (Backblaze B2)
Hyper Backup on Synology hosts handles encryption before upload
B2 API key is stored in ~/.b2_env and is compatible with AWS CLI S3 API
The sanitize.py script redacts B2 credentials before public repo mirroring
