proxmox-backup Proxmox PVE1/PVE2 config backup to GitHub — weekly cron, restore script, repo structure
node_type type originSessionId
memory project c454fc50-f93d-4ddd-b9f3-f3f442e89fb9

GitHub repo myronblair/proxmox-config (private) — full config backup + disaster recovery.

Why: So both Proxmox nodes can be rebuilt quickly from scratch after hardware failure without losing VM configs, network, custom scripts, or services.

How to apply: Reference this when discussing Proxmox maintenance, DR planning, or if a node goes down.

Repo Structure

  • shared/ — cluster-wide: all VM/LXC .conf files, storage.cfg, datacenter.cfg, user.cfg, corosync.conf, jobs.cfg, firewall, ha, sdn
  • pve/ — PVE1 (10.48.200.90): network, cron, scripts, systemd (filebrowser, jarvis-agent, ollama), ssh/authorized_keys
  • pve2/ — PVE2 (10.48.200.91): network, cron, scripts (just pve-remove-nag.sh), systemd (jarvis-agent)
  • backup.sh — runs on each node, pulls repo, collects files, commits+pushes
  • restore.sh pve1|pve2 — interactive disaster recovery wizard

Schedule

Weekly cron on both nodes: 0 3 * * 0 /usr/local/bin/proxmox-backup >> /var/log/proxmox-backup.log 2>&1

Manual trigger

/usr/local/bin/proxmox-backup on either node

What's NOT backed up (intentional)

  • /etc/pve/priv/ — CA private key, cluster auth keys (Proxmox regenerates these)
  • SSH private keys
  • Large binaries: ollama, filebrowser, blockalign, urbackupclientctl
  • VM disk images → covered by PBS at 10.48.200.85

Restore flow

  1. Fresh Proxmox install → set hostname + IP
  2. apt install git && git clone https://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@github.com/myronblair/proxmox-config.git /opt/proxmox-config
  3. bash /opt/proxmox-config/restore.sh pve1 (interactive, confirms each step)
  4. Reboot for network, then restore VMs from PBS

PVE2 disk space issue (2026-06-09)

PVE2 was at 100% disk — removed old kernels to free ~9GB. Now at 96% (4.4GB free). Worth monitoring.
