## Purpose
This script is ran via cronjob on `cluster-node-02` at midnight to rollback the deeplab environment automatically to a previous snapshot nightly.

### Bash Script

```sh title="/root/deeplab-rollback.sh"
#!/usr/bin/env bash
# ProxmoxVE Nightly DeepLab Rollback Script

SNAPNAME="ROLLBACK"

DC=140
WIN10=141
WIN11=111
ALL=("$DC" "$WIN10" "$WIN11")

log(){ echo "[$(date '+%F %T')] $*"; }

# Force Stop DeepLab VMs
for id in "${ALL[@]}"; do
  log "Force stopping VM $id"
  /usr/sbin/qm stop "$id" || true
done

# Rollback Snapshots
for id in "${ALL[@]}"; do
  log "Rolling back VM $id to snapshot $SNAPNAME"
  /usr/sbin/qm rollback "$id" "$SNAPNAME"
done

# Start DC
log "Starting DC ($DC)"
/usr/sbin/qm start "$DC"

# Wait 2 minutes
log "Waiting 2 minutes for DC to initialize..."
sleep 120

# Start Win10 + Win11
log "Starting WIN10 ($WIN10) and WIN11 ($WIN11)"
/usr/sbin/qm start "$WIN10" &
/usr/sbin/qm start "$WIN11" &
wait

log "Lab Rollback Complete."
```
