If you're anything like me, and you're using your FreeBSD box to run samba as well as a squid cache.. actually, I don't think there's any sort of an intro which is going to make this tech tip sound like it's at home.
I was trying to use Robocopy with /MIR in order to sync up some files between a samba share and my main box. My first copy worked fine and all files/directories were copied over as expected. However, the second copy also attempted to copy everything again. My google search was interesting - a lot of people were talking about how they're doing this, and it works fine etc. A few people mentioned that they were having the same problem as me and couldn't work it out!
What very few people mentioned is that you need to use the /FFT switch when copying between NTFS and Linux/Unix/FAT file systems. This forces Robocopy to use FAT style timestamps which have a granularity of 2 seconds. Switch added to the backup batch file, and all is well!
