This might be old news for some, but I have been hearing some talk that Synctoy misses files. I decided this time to run my backup with Robocopy, which is an included tool on newer Windows OS. By default it only copies the files that are new or changed. I should have been up to date with Synctoy up to a month ago. However, when I ran Robocopy, it found HUNDREDS of files from the past 2 years than Synctoy had not updated or just not copied. Total missed files copied were over 30GB. That's pretty scary for a backup.
I'd advise using something else. I'll probably just make a robocopy batch file I can double click after downloading a big shoot.
