How to backup Synology NAS to external hard drive

Synology NAS provides convenient backup options to back up data to external hard drives, cloud storage, or file servers through the official application Hyper Backup.

What is Synology NAS?

If you need a NAS or network-attached storage unit, Synology is a good option to consider. They offer a variety of options, including backing up your data to an external SSD, hard drive, or other USB drive, ensuring you're always online.

Before you begin, you should remember a few things:

• You need to install DSM 6.0 or higher to use Hyper Backup. If you didn't know, DSM stands for DiskStation Manager, which helps your Synology NAS run.
• The external hard drive must be connected to your Synology NAS, and the connection should not be interrupted at any time.
• For obvious reasons, your external hard drive must have a larger capacity than the required data you want to back up.

To get started, log in to DiskStation Manager or DSM, and download Hyper Backup. If you already have the app installed, just open the app, tap the plus sign ( ) in the lower left corner, and select the Delete Data Backup Task option.

It will open the backup wizard. Here, you need to select the local folder and USB options and click on the Next button.

Then, select the Create backup task option, select the external hard drive connected to your Synology NAS, and click the Select Next button.

You can now select the folders or applications you want to back up. Navigate to the path and check the items, then click Next.

Next, you can find some options you need to set to customize your backup. For your reference, you can find the following:

• Enable task notifications: Check this checkbox if you wish to receive notifications.
• Compress backup data
• Enable Backup Schedule: It helps you schedule backup so that data is automatically stored in your external hard drive.
• Enable integrity check schedule
• Enable client-side encryption

After completing these options, click the "Next" button.

If you select the automatic data backup option, it will ask you to enable backup rotation. In other words, you can only store the latest version of your data, and it automatically deletes or replaces all other older data. We recommend that you enable this option and select the "Start from earliest version" option.

After completing all these settings, click the Apply button. Now that you have done everything, you can click the Yes button to start backing up your data immediately.

That's it! I hope it helps.
