Very true, I was really thinking of atime which is commonly disabled (on unix systems using the mount option noatime for example). However, I suspect in this case, exchange treats the "file" like a database, and almost like a filesystem itself. Therefore it is perfectly possible that it has a method to disable mtime updates as well (I wonder, does a file containing a FS which is mounted (/dev/loop0), and written to, update the mtime of the file?).
Anyway, I think there have been a number of good options so far: 1) Use touch from a scheduled task (cron) to update the date/time on a regular basis 2) Use touch from backuppc as a pre-backup job 3) Use --checksum for rsync to force it to ignore the date/time and size, and backup based on contents Regards, Adam -- Adam Goryachev Website Managers www.websitemanagers.com.au ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
