Can I automatically mirror folders to Synology NAS?

"I have a folder C:\Documents on my local computer. I'd like that folder automatically synced to a similar folder on my Synology DiskStation so that any changes I make on the C:\Documents folder are copied to the folder on the DiskStation. Does that make sense?"

In fact, Synology provides you with 4 data migration software to sync files and folders between two Synology NAS, between Synology NAS and your computer or within Synology NAS: File Station, Cloud Station ShareSync, Shared Folder Sync, and Snapshot Replication.

For the above case, you need to use Cloud Station to perform the Synology mirror folder. It is a file synchronization tool for you to sync files between your Synology NAS and other devices (like computers, DS cloud, etc.)

Synology Cloud Station Series of Packages Ends 

According to Synology, it will disconnect supports for Cloud Station series on the DSM platform on April 30, 2021. But you still can use it and receive security updates if you are 1.2.x SRM platform users (RT1900ac, RT2600ac, MR2200ac). And the same is true for Cloud Station companion mobile app, and DS cloud.

Thus, if you want to continue using it, you can turn to the1.2.x SRM platform or companion mobile app, and DS cloud. Besides, there is a quick way to perform Synology folder sync, it's to use a comprehensive file sync software to achieve this goal.
