Bare-metal backup server
Institutional data centre
Rebuilt a bare-metal server as the cluster's backup server: automated backups of every guest, reachable only by the cluster and authorised admins.
What I built
- Proxmox Backup Server with tiered retention and verified restores
- Default-deny firewall, brute-force protection and key-only access
- Zero-trust admin access with an out-of-band fallback
