Try giving the "--size-only" option to rsync.

Better yet, try "--modify-window=1". From the rsync man page:

--modify-window
                 When  comparing  two  timestamps, rsync treats the
timestamps as
                 being equal if they differ by no  more  than  the
modify-window
                 value.   This  is  normally  0 (for an exact match),
but you may
                 find it useful to set this to a larger value in some
situations.
                 In  particular,  when  transferring to or from an MS
Windows FAT
                 filesystem (which represents times with a 2-second
resolution),
                 --modify-window=1 is useful (allowing times to differ
by up to 1
                 second).

Hi Pat,

--modify-window=1
        3 hr - 9 sec

--modify-window=10
        3 hr - 8 sec

Rat!  I really though this sounded right


I did notice that the bugger the file (with no changes)
the longer it took.  So, I think they are still doing
check sums.

Any way to turn of the check sum testing?

Now you're starting to get off task... How can you sync something if you
don't know if it matches? Sure, you can only go off timestamps

How would I do size and time stamp?

Virtually everything I modify will either be a different size
and/or get a new time stamp.  I can not think of a reason
why, in this instance, I'd need to do a check sum.

Then you don't want to use rsync - as you're not syncing. rsync will
also checksum data AFTER copying to verify the copy was successful.

If you don't care about the rest, try the normal cp:
        cp -apu /path/to/source /path/to/destination



One of the things I like about rsync is that I can
get rid of the defunct stuff on the stick.  I suppose
I could write a subroutine (function I think they call
it in bash) to do that before cutting loose the cp
