[EMAIL PROTECTED] ~]$ echo 'hello' > foo.txt [EMAIL PROTECTED] ~]$ ls -l foo.txt -rw-r--r-- 1 hyclak faculty 6 Aug 10 21:28 foo.txt [EMAIL PROTECTED] ~]$ echo 'help!' > foo.txt [EMAIL PROTECTED] ~]$ ls -l foo.txt -rw-r--r-- 1 hyclak faculty 6 Aug 10 21:29 foo.txt Notice that the file size is still 6 for both versions of that file. You probably don't want to only back up based on size. Anyway, it may not be atime that's being modified, it could be the mtime or maybe even ctime. You're going to have to figure out what it is that is causing the files to change. Ignoring files that don't change size is a bad way to fix the problem. Perhaps someone else can jump in here with a better knowledge of filesystem internals. Matt -- Matt Hyclak Department of Mathematics Department of Social Work Ohio University (740) 593-1263
