envious

I need to do a clean install of my Windows 10 machine. Right now I have Resilio set up with an off site peer that has about 150gb of data that I sent him. If I reinstall windows, and reinstall Resilio Sync after that, do I need to send him 150gb again? I want to keep the folder that contains 150gb synced after the clean install as well. Transferring 150gb again is not ideal, and I want to avoid that.
