Replacing WDSync to Sync Folders 7 Layers Deep

What can we use to replace WD Sync from Western Digital MyCloud?
I don’t want to change out the firmware or the basic configuration on MyCloud. All we are doing is syncing several directories, which are 7 layers deep in folders so that 3 people, one inside the office and two outside the office, can keep their AutoCAD directory and Files directory in sync.

My best bet is that you can also use a scheduled backup option; you can find the WD SmartWare directly from our website.

I’ve recently been using FreeFileSync which seems to be quite good. You may wish to have a look here: http://www.freefilesync.org/

Another product I’ve used in the past is AraxisMerge. Here: https://www.araxis.com/merge/
