Backing up partitions to another drive. Ran afoul of the timestamp
issue: no -t on original transfer. Didn't use rsync to do it.

So now, using -n to keep things from screwing up, I get all the files in
the logfile, and -stat agrees that it should all get recopied.

Question: If I now include the -t, does it in fact transfer all the
files again, or does it compare the checksums and update the time stamp
without transfering all the files themselves? I can't figure this out
from the man file...

Thanks for any help,
