The mail I was referring to indeed mentioned mtimes, sorry for that.
So, as far as I understand your replies, there is no way to prevent
rsync from comparing at least size/mtime of each and every file because
file contents can change without any flag/time/whatever of the directory
the file is in changes?
That's strange, shouldn't sth. change in the directory information if
a files status in the directory changes? Sth. like the archive flag in
FAT/NTFS?
The problem is that even just comparing sizes/mtimes can take hours
on a 12 TB raid of there are hundreds of directories and each has
25 million files in it :-o so I hoped for a shortcut for unchanged
directories.

Frank
