[aklug] Re: rsync help

Just moving files around on my hard drive, I'm finding that if I do this:

rsync -vru src_dir/ dest_dir/

It'll have the undesired effect of resetting all the timestamps to now.

If I then do this:

rsync -vrtc src_dir/ dest_dir/

It doesn't re-copy the files, but instead updates the timestamps (as
-c is supposedly using checksums only to determine updates).

This on rsync version 2.6.9. By no means am I an rsync guru. I'd, um,
find a way to verify this first on your own systems. Mileage may vary.
