How to Select an Old NAS and select a New Synology Data ...

If you are switching from an old Synology to a new Synology NAS or simply want to keep two of these in sync at once, the simple-yet-effective solution Ive found is to use shared folder Sync with rsync. This is very simple in the Synology web control panel. Here''s how.

I have upgraded from a two-bay Synology DS720+ to a four-bay Synology DS920+ model. The upgrade allows me an additional performance and two additional drive bays for storage expandability. A NAS is a great companion to an Apple household, as it can serve as a Plex media server for all your devices, restart your Macs with Time Machine, and more. A complete review of the DS920+ is coming soon.

I wanted to keep the old NAS in place, so I couldnt take out the hard drives and physical move the data that way. I also wanted an option that could be performed in the background while the old NAS remained active (our family relies on it for Plex access and other services).

If I added files to the old NAS before I had completely migrated to the new box, I wanted to do so again in the future. It was also unclear how that would be accomplished.

The best option I found was to use the advanced rsync service with the Synologys shared folder synchronization app. This proved to be a very simple and elegant solution that could be set up autonomously using the web UI, even though the steps were somewhat non-obvious.

How to establish shared folder synchronization from one NAS to another

1. Pass the Synology DiskStation web portal on the new NAS, which is the destination you want to copy/sync files to. Go to Control Panel -> File Services -> rsync, and initiate the rsync service.

2. Navigate to Control Panel -> File Services -> Advanced and select Shared Folder Sync on the old NAS.

3. Click on the Task List button and press Create. Select the source shared folder you want to copy. NOTE: If the directory/file names match with the destination, they will be renamed so they won''t be interfered with the sync process.

Follow the steps by pressing the Next button. The Synology should automatically detect the new Synology on your network, so you may select it from the list and enter your login credentials.

The files and folders will automatically begin syncing over the network to the new NAS. If you add files later to the source, those will also be copied across to the destination. In order to reduce traffic congestion on your local network, you may configure the task to only run on a regular basis at certain times of the day (like at night).
