I could use an ordinary copying script for the mail files, but I figured if
rsync can do it in some more optimal way, I'll stick with it for simplicity
(since it's working great for the several hundred gigs of user files).
I saw the -W option, but I wasn't sure about how it behaves as the man pages
don't have many details, and I thought there might be other options I
missed. For -W the man page just says "copy files whole (w/o delta-xfer
algorithm)"
Does that mean it will copy all files with no comparison, or does it at
least verify that there is some change to the file first? I suppose either
way I can test it to see, which is faster, but if someone can clarify the
behavior I'd appreciate it.
Thanks,
David

Can anyone suggest a good way to speed up rsync on really large files?
In particular, when I rsync the mail spool directory, I have a few users
with inboxes over 1GB and up and it seems to take a very long time to
just compare the files. Maybe it would be faster to copy from scratch
for files over a certain size or something if the time stamps don't
match.

rsync is meant to safe bandwidth, that's the main use of the tool. If you
have enough bandwidth, rsync without options might not be how you want to
use it.
Their is -W for whole files.
