The importance of Synology replication between two NAS
Network-attached storage (NAS) is a file-level computer data storage server that enables users to collaborate and share data. As one of the most famous manufacturers, Synology has been specializing in NAS devices for many years. Many users are loyal fans of Synology NAS devices, mainly because these high quality devices are super-easy to use and set up.
Even if you use such an advanced NAS device, sometimes you have to perform Synology replication between two NAS, simply put, a NAS to NAS backup. Due to a sudden hardware failure, natural disaster, accidental deletion or other unknown reasons, it’s quite easy for NAS users to lose their data.
Additionally, for larger capacity, you may intent to replace the current NAS device. However, you don’t want to discard the old data. All you can think about is transferring data from the old device to the new device. To keep data safe and transfer data more efficiently, you’d better do a Synology NAS to NAS backup.
How to create Synology replication between two NAS
Synology NAS to NAS replication can be performed easily, as long as you take the right approach. Luckily, two simple but proven methods are listed here. Please continue reading the detailed instructions.
Method 1. Backup Synology NAS to another NAS via File Station
As you know, DiskStation Manager (DSM) is an intuitive web-based operating system for every Synology NAS. File Station, a practical application included in the DSM, allows users to transfer files between two Synology NAS devices with their web browsers.
For more information about downloading and installing DSM, see the Synology official website. Suppose you have configured DSM and File Station. Now, you can follow the steps below.
Step 1. Open a web browser to log into DSM. Visit Main Menu to open File Station.
Step 2. Choose Settings to click Enable drag and drop between browsers. Also, you can enable the smart drag and drop. Then click OK.
Step 3. Perform those steps in both NAS devices. Now, you can directly drag and drop files/folders between them via File Station.
Make sure that the shared folder is already created in NAS.
You are allowed to drag and drop files/folder between two tabs of the same browser.
Internet Explorer does not support drag and drop between browsers or between tabs.
This traditional copy-paste method serves you well if you only have a small number of files or folders. However, this method could be a very huge work when you need to transfer large amounts of data. In addition, data loss might occur if you make a mistake in the process. Is there an easy but reliable way to copy NAS to NAS? The answer is yes, if you turn to the second method.
