Guest Michael Posted July 12, 2007 Posted July 12, 2007 Can anyone explain to me why robocopy always tries to copy some files everytime it syncs the source and destination even though the files haven't been modified in some cases for days, months or years? The options I used are: Source : \\xyz\abc Dest : \\def\jkl Files : * Options : /TEE /S /E /COPY:DAT /PURGE /MIR /R:1000000 /W:30 The files that do get modified are always changed on the source and the destination serves as a backup repository. The sync would only go the other way to restore the lost source system. The files get updated by both PCs and Sun workstations and the source is also an NFS server using Hummingbird 2007. Thank you, Michael P.S. I changed the source and dest values since they refer to my workplace servers.
