🌟 Quick Look

Backing up your Synology NAS to an external drive is a reliable way to secure your data locally against network failures, hardware issues, or ransomware. This guide covers three practical methods to complete the transfer efficiently, depending on your workflow and backup preferences.

  • CBackup: Excellent for Windows users managing multiple local devices. It offers automated scheduling, incremental backups, and file synchronization, though it focuses on file management rather than full NAS system configurations.

  • Synology Hyper Backup: The most comprehensive native option. It supports multi-version retention, data deduplication, and system setting backups. It stores data in a secure, proprietary database that requires Synology tools to read.

  • Synology USB Copy: Ideal for quick, direct file viewing. It creates a direct mirror of your folders in their original format so you can plug the drive into any PC or Mac, but it lacks advanced compression and system setting backups.

Choosing the right approach depends on whether you prioritize advanced version history, system settings, or immediate, cross-platform file access.

How to backup Synology to external drive?

When looking for the best way to backup Synology NAS, many users prefer a direct local connection. You can easily backup Synology NAS to external drive to keep your data safe from network failures and other unforeseen events. There are some tools provided by Synology for this process.

Method 1. Backup Synology to external drive with CBackup

If you are looking for a flexible and efficient way to back up a Synology NAS to an external drive, CBackup is one of the strongest choices for Windows users. It is designed to simplify local backup and synchronization tasks while keeping files consistent across computers, external hard drives, and NAS devices.

★ Some key benefits include:
Beginner-friendly interface with advanced backup settings
Support for file, partition, disk, and system backup
Scheduled backups for automatic data protection
Real-time synchronization to keep files updated
Mirror sync support for identical file copies
Incremental backup technology that transfers only changed data
Reduced network traffic and storage usage during backup
Full system and file recovery after crashes or hardware failure
Bootable recovery support when Windows cannot start normally

However, unlike some NAS native tools, it mainly focuses on Windows based backup management rather than complete NAS system configuration backup. Users who need application level NAS settings or proprietary NAS backup features may still rely on additional Synology tools in certain situations.

This solution is especially suitable for users who manage multiple local devices, USB drives, and NAS storage within the same network. It works quietly in the background and keeps important data protected without affecting normal daily work. For users who want centralized backup management, automatic synchronization, and dependable recovery options, CBackup provides a smooth and reliable way to protect a Synology environment.

Step 1. Download the Synology NAS backup software on your computer. With it, you can also back up Windows 11 to Synology NAS.

Method 2. Backup Synology to external drive via Synology Hyper Backup

Using Synology Hyper Backup with a USB drive is widely considered one of the most reliable ways to protect data. It creates a secure backup vault for files while providing advanced backup and recovery capabilities for long-term protection.

★ Some key benefits include:
Data deduplication to reduce unnecessary storage usage
Compression support to save disk space
Local encryption for better data security
Multiple file versions without using too much storage
Backup support for system settings and application configurations
Automatic scheduled backups for easier management
Better protection against accidental deletion, corruption, and ransomware

However, it stores backup data in a proprietary database format. This means users cannot directly connect the USB drive to another computer and browse the backup files like normal folders. To view or restore the backup content on a PC or Mac, the dedicated recovery tool from Synology is required.

This method is especially suitable for users who need scheduled backups, stronger security, and version history. After the initial setup, backups run automatically based on the selected schedule. It also keeps historical file versions, making it easier to recover from accidental deletion, damaged files, or ransomware attacks. For many users, it remains a dependable disaster recovery solution for important NAS data.

Step 1. Connect your external drive to the available port on your Synology NAS.

Step 2. Sign in to DSM, open Package Center, and install Synology Hyper Backup if it is not already installed.

Step 3. Launch Hyper Backup, click the plus icon in the upper left corner, and select Folders and Packages.

Step 4. Choose Local Shared Folder and USB as the backup destination, then select your connected external drive.

Step 5. Select the shared folders and applications you want to back up.

Step 6. Configure the backup settings, including task name, schedule, compression, notifications, integrity check, and encryption if needed.

Step 7. Enable backup rotation and choose a version retention method such as Smart Recycle or custom version limits.

Step 8. Click Apply to save the task settings, then select Yes if you want to start the backup immediately.

Method 3. Backup Synology NAS to external hard drive with Synology USB Copy

If you prefer a simpler way to back up a Synology NAS to an external drive, USB Copy is a practical option. It is designed for quick and convenient file transfers, making it especially suitable for users who want to build a Synology mirror NAS setup with files copied exactly as they appear on the original device.

★ Some key benefits include:
Files remain in their original format for direct access
External drives can be opened on most computers without extra software
Automatic copy tasks on supported NAS models
One-button backup support on compatible devices
Simple folder mirroring for synchronized backups
Faster and more straightforward recovery procedures

This method focuses on simplicity and accessibility. Since it does not use deduplication or compression, the external drive may consume storage space more quickly than dedicated backup solutions. It also copies files only, so system settings, applications, and NAS configurations are not included as they are with Synology Hyper Backup.

For many users, however, that tradeoff is worth it. Whether you're storing years of photos, creative projects, or important family files, having an extra copy on an external drive offers valuable peace of mind.

After the initial setup, the sync task automatically updates the external drive whenever files change on your Synology NAS. Your backup stays current in the background, making it easy to access or restore files whenever needed.

Step 1. Connect your portable drive to the NAS.

Step 2. Navigate to the Package Center and install the USB Copy application.

Step 3. Open the application and click the plus icon to add a new job.

Step 4. Choose your desired mode, such as Data Copy, to enable mirroring.

Step 5. Select the source folder you want to copy and set the destination folder on your portable storage.

Step 6. Adjust the settings to trigger the process automatically upon connection.

Step 7. Apply the settings and allow the initial copy process to complete.
