FreeFileSync freezes after 6 hours of synchronizing 600+ GB files. I have to terminate the process finally. Is there a way to backing up such amount of files? No big files, but gigantic amount of small ones, probably millions. Operating on Windows 10 64 bits. Thanks in advance!

Something similar happens to me but with only a few GB of various files to sync.
Me too I'm on Windows 10 64 bit.
The problem goes away deactivating Windows Defender just for the time needed to sync.

If you're using the recycle bin for deletions/overwrites then this might be why FFS is hanging (at the end), in which case it should be waited until it's finished. Ideally FFS wouldn't hang the UI thread but run this in a worker thread to appear responsive, but still this would be cosmetics only.

Thanks! I'll try it next time. Plus, it was my first time to run the sync so there is no deletion, only copying to the backup folder.
