backup

I am trying to use Robocopy to sync (/IMG) a folder on my PC and a shared network drive.

The problem is that the file attributes differ by 1 sec on both locations (creation,modified and access). So every time I run robocopy, it syncs the file again...

BTW, problem is the same if I delete the target file and robocopy it from new... still, new file has 1 sec different properties.

Env Details:

Source: Win 7 64 bit
Target: WD My Book World Edition NAS 1TB which takes its time from online NTP pool.ntp.org (I don't know if file system is FAT or not)
