synology backup to another synology

To keep your Synology NAS data safe, you can back it up to another Synology device. Why? Because that would ensure that you have a secure and stable system that enables you to save data from multiple sources, including other NAS devices.

Since NAS is a cutting-edge high-capacity storage solution of the 21st century, it’s only natural to rely on its storage options when saving your data. Read on to discover several backup methods to back up a Synology NAS to another NAS and the reasons to do this.

Steps to Take Before Backing Up Synology NAS to Another NAS

Before copying data between two Synology NAS devices, you must meet specific requirements to ensure your data is safe and secure. First, check your NAS connections to ensure both NAS devices share the same network.

Then, check the receiving NAS’ available space to ensure it can receive the files you wish to back up. In addition, you should decide how you want to sync your files. You have two options:

  • One-way sync – back up your data to the receiving Synology NAS device but keep the primary data source unchanged.
  • Two-way sync – this option will synchronize both NAS devices. Deleting data from one device will also delete the backup data on the other NAS.

Finally, decide whether to back up your data to another NAS manually or automatically. Keep reading to learn how to manually and automatically back up a Synology NAS to another NAS.

Why Back Up Synology NAS to Another Synology NAS

Synology backup NAS to NAS is the process of saving data from one Synology NAS to another. There are many reasons you would want to back up Synology to Synology, such as:

  • Avoiding data loss – If one NAS device fails, you’ll have a readily-available data backup on the other device. On the other hand, your data could become unavailable due to multiple users storing it on the same NAS device. Even though NAS is an ultra-fast and efficient storage device, you shouldn’t leave anything to chance.
  • Freeing up space on your NAS – If you have multiple files you don’t use that often, you can move them to another NAS device for safekeeping to free up space on your primary Synology NAS.
  • Accidental deletion – It’s so easy to delete precious data accidentally. Before you know it, your data is gone. That’s all the more reason to consider creating a Synology NAS to NAS backup of your data to recover deleted files from Synology NAS.
  • Improving performance – Moving infrequently-used data to a secondary NAS device effectively enhances performance on the primary system by reducing the load.
  • Creating offsite data backup – If a natural disaster destroys or damages your primary NAS system, an offsite data backup will help you restore your operations.
  • Transferring NAS data – You can back up a Synology NAS to another NAS to avoid manually migrating data from an old device to a new one.

These are all legit reasons to consider the Synology-to-Synology backup option.


NAS devices are becoming a standard in the data storage realm. You can rely on Synology NAS to store and back up your data safely and securely. However, NAS devices typically come with a limited storage capacity.

If your primary NAS runs out of data storage, you can free up the space by backing up your files to another Synology NAS. Whether you prefer to do it yourself or use a third-party app, a NAS-to-NAS backup is an excellent safety option to avoid data loss.
