Backup Installation¶

This guide covers installing Proxmox Backup Server (PBS) for your TAPPaaS infrastructure.

Overview¶

Proxmox Backup Server provides:

• Incremental backups with deduplication
• VM and container backup support
• Encrypted backup storage
• Automated retention policies

Installation¶

Run Installation Script¶

From the tappaas-cicd VM:

cd ~/TAPPaaS/src/foundation/backup
./install.sh

The script automatically:

1. Create the PBS datastore (tappaas_backup)
2. Create the tappaas@pbs user
3. Set permissions for the user on the datastore
4. Configure retention policy (4 last, 14 daily, 8 weekly, 12 monthly, 6 yearly)
5. Get the PBS fingerprint
6. Add PBS storage to Proxmox datacenter
7. Create a daily backup job at 21:00 for all VMs
8. Register DNS entry in OPNsense (backup.mgmt.internal)

For backup operations, restoration, monitoring, and troubleshooting, see the Backup Manual.
