2 Easy Ways to Run Synology Bidirectional Sync in Windows


Need Synology bidirectional folder sync

Nowadays, more and more people would like to store their files on a NAS device or cloud drive for data protection or file sharing. And it is wise to have important files saved on both NAS and cloud to strengthen data security. How to have a folder with same files on the two places?

Two-way sync between your NAS and the cloud service is the answer. One user asked about Synology 2-way folder sync in the forum:

“Hi, I want to sync my Google photos online with my Synology. My Google photos online are within Google Drive, in a folder called ‘Google photos’. Currently I have partial photos in Google Drive (online). And partial photos on my Synology in a folder called ‘Google photos’.

If I select bidirectional, will it combine all the photos, local and online (that's what I want)? I do not want to duplicate and I do not want to delete anything.”

In this page, I’ll dwell on two efficient ways to do Synology 2-way sync. Method 2 can not only help you run two-way sync between Synology NAS and cloud storage but also between Synology NAS and your PC.

Method 1. Use Synology Cloud Sync for bidirectional folder sync

To help to sync files between Synology NAS and public cloud services, Synology provides users with an application called Cloud Sync. It supports various cloud services, like Amazon Drive, Dropbox, and OneDrive. Take Dropbox as an example. Follow the steps below to run Synology two-way sync with Dropbox:

1. Install Cloud Sync from the Package Center and open it.

2. Choose a cloud provider.

Choose Cloud Provider

3. Create a two-way sync task.

4. Confirm your settings and click “Apply” to begin the syncing process. If needed, click “Advanced settings” to prevent certain files from being synced before clicking “Apply”.

Method 2. Run Synology bidirectional sync via a professional sync tool

The operations in Synology Cloud Sync are not complicated. However, users find Synology Cloud Sync not working sometimes or Synology Cloud Sync not syncing all files. Is there a superior tool to Cloud Sync?

Qiling Disk Master Professional can be the best Synology Cloud Sync alternative. It runs smoothly on Windows 11/10/8.1/8/7/Vista/XP. It allows you to sync files between two folders, drives, or computers. You are also allowed to sync NAS with a cloud drive, such as sync QNAP to OneDrive.

What’s more pleasing, it offers different sync modes for different needs:

★ Basic Sync: it performs one-way sync from the source directory to the destination directory.
★ Real-Time Sync: it synchronizes changed files in the source directory to the destination directory almost without delay.
★ Mirror Sync: it keeps the files in the destination directory exactly the same as the source directory. Any extra files in the destination directory will be deleted.
★ Two-Way Sync: Any changes in the source or destination directory will be synced to the other side.

Step 3. After Synology NAS has been added, all the folders under it will be listed. Choose the folder you want to sync and click OK.

✎ Tips: You can only choose one source folder when creating a two-way sync task. If you want to set multiple folders to do two-way sync, then create different sync tasks for them and choose different destination folders.

Step 4. Expand the drop-down menu of the second bar and choose Select a cloud drive.

Step 5. Select Dropbox and click OK. If you cannot find Dropbox in the list, then manually navigate to the Dropbox local folder by clicking the folder shaped button in the second bar.

Step 6. Confirm the source and destination directory and click Proceed.
