Snapshot Runbook — Before Major Changes
Last Updated: 2026-02-07
Purpose: Create Proxmox snapshots before major changes for quick rollback.
See: OPERATIONAL_RUNBOOKS.md, PRE_START_CHECKLIST.md
When to Create Snapshots
- Before upgrading Besu or other critical services
- Before configuration changes (nginx, NPMplus, etc.)
- Before OS/package upgrades in containers
- Before migration (storage, host, network)
Commands
LXC (containers)
# Create snapshot (use pct on Proxmox host)
pct snapshot <VMID> pre-<change>-$(date +%Y%m%d-%H%M%S)
# Examples
pct snapshot 1000 pre-besu-upgrade-20260207
pct snapshot 10233 pre-npmplus-config-20260207-120000
# List snapshots
pct listsnapshot <VMID>
# Rollback (if needed)
pct rollback <VMID> pre-<change>-YYYYMMDD
QEMU/KVM (VMs)
qm snapshot <VMID> pre-<change>-$(date +%Y%m%d)
qm listsnapshot <VMID>
qm rollback <VMID> pre-<change>-YYYYMMDD
Via SSH from repo
# From project root
source config/ip-addresses.conf
# Create snapshot on r630-01 for VMID 10233
ssh root@$PROXMOX_R630_01 "pct snapshot 10233 pre-change-$(date +%Y%m%d-%H%M%S)"
Retention
- Keep 1–3 recent snapshots per VMID
- Delete old snapshots:
pct delsnapshot <VMID> <snapname> - Snapshots consume storage; monitor disk usage
Checklist
- Identify VMIDs affected by change
- Create snapshot on each Proxmox host for those VMIDs
- Document snapshot names for rollback reference
- Proceed with change
- If rollback needed:
pct rollback <VMID> <snapname>
