I am trying to sync LARGE folder from a Windows Machine to any other device (at the moment a Raspberry Pi with a USB Drive, but if I get this working it will be any other device). Large is just shy of 3TB. My thinking was that while I have access to USB I could pre-sync the folder by simply copying files over and then running BTSync to mirror any additional changes. Sync of course wanted to overwrite every file on the Pi. I am assuming due to changes in the file attributes triggering sync to replace them. Trying to use Sync across the lan will take roughly a Month and is outside the bound
