1. Proxmox Backup
   → Full system recovery

2. Home Assistant Backup
   → Fast HA-only restore

3. Synology Hyper Backup
   → Versioned local backup

4. Cloud Sync (OneDrive)
   → Offsite backup - daily 5am - hyperbackup sync + raw backups folder (proxmox, ha, paperless)

• Media files are excluded from cloud backup
• Focus is on critical infrastructure and configuration
• Restore via:
• Proxmox (full VM/CT restore)
• Home Assistant (snapshot restore)
