I would say this is an MS Office flaw. If _nothing_ is, neither ctime nor mtime should be updated. > Could it be possible to use the mtime value instead of ctime to avoid > the the reappearance of the unchanged files in the incremental archive? Use a find command to build a file list of all files changed since last backup. Personally I highly recommend differential against last full rather than incremental, but that is a different discussion. Also, you might reach out to Microsoft for why they are modifying any timestamp if nothing was changed. -- Erik -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
