Hmmm, as I fiddle with RoboCopy, I'm not in love with some of the compromises involved. It essentially ends up as a glorified bat file, which isn't the direction I was hoping to go. And having to restart the computer is a big minus.


I just realized, however, that I don't need to compare timestamps with the flash drive files. I store the timestamps of when I do each backup. I can just copy all source files (files on the hard drive) with a modified date after the last backup. I could even toss out the size comparisons.

Can anyone think of examples that would trip up this approach? Any way files get modified without their modified date getting updated?
