How to backup CloudPanel installed on a Synology NAS

To back up CloudPanel installed directly on a Synology NAS, you’re likely running it inside a Docker container, possibly using Synology’s Docker GUI. Here’s how to properly back up the CloudPanel instance and its associated data:

🔄 Backup CloudPanel on Synology NAS (Docker)

📁 Step 1: Identify What to Back Up

You need to back up:

• CloudPanel container volumes (websites, configs)
• Database container volumes (MariaDB/MySQL)
• Any custom docker-compose.yml or configuration files

To locate them:

Option A: Using Synology GUI

1. Open Docker > Container > Select CloudPanel > Details
2. Check the Volumes tab to find the mapped folders
   • For example: /volume1/docker/cloudpanel

Option B: Using SSH

bashCopyEditdocker inspect <cloudpanel_container_name> | grep Mounts -A 20

🗃️ Step 2: Backup Strategy

🧠 Option 1: Use Hyper Backup (GUI method)

1. Open Hyper Backup on Synology.
2. Choose Local Folder & USB, Remote NAS, or Cloud Storage as destination.
3. Select the Docker-mapped folders (e.g., /volume1/docker/cloudpanel, /volume1/docker/mariadb)
4. Schedule backups and enable rotation.

⚙️ Option 2: Manual rsync or cronjob (CLI method via SSH)

Create a backup script to compress the relevant folders.

bashCopyEdit#!/bin/bash

BACKUP_DIR="/volume1/backups/cloudpanel-$(date +%F)"
mkdir -p "$BACKUP_DIR"

# Backup CloudPanel data
rsync -a /volume1/docker/cloudpanel/ "$BACKUP_DIR/cloudpanel-data/"
rsync -a /volume1/docker/mariadb/ "$BACKUP_DIR/mariadb-data/"

# Optional: Backup Docker Compose file
cp /volume1/docker/docker-compose.yml "$BACKUP_DIR/"

# Compress it (optional)
tar -czf "$BACKUP_DIR.tar.gz" -C /volume1/backups "cloudpanel-$(date +%F)"
rm -rf "$BACKUP_DIR"

Then schedule it with crontab -e:

bashCopyEdit0 2 * * * /volume1/docker/backup-cloudpanel.sh

---

💾 Step 3: Backup the Databases Properly (Optional but Recommended)

If using MariaDB in a container:

bashCopyEditdocker exec <mariadb_container_name> \
mysqldump -u root -p'yourpassword' --all-databases > /volume1/docker/backups/all-databases.sql

---

🔁 Step 4: Automate & Rotate

For long-term safety:

• Enable Hyper Backup rotation or manually delete old .tar.gz files.
• Test restoring by spinning up a test container with the backed-up volumes.
