Vista - Robocopy question using Vista

I use robocopy to backup critical files to my server each night (or
morning). And it works very well. However, I've noticed that if I run the
exact same routine 2 times in a row, it still copies some number of files
each time. Granted it's a small number of files (say 6 out of 200). I'm
just curious if anyone else has noticed this behavior and if you have any
ideas why this happens. I know that none of the files have changed between
to successive runs. I have included the contents of my batch file below
(it's really quite simple):

@echo off
echo .
echo Begin Synchronizing...
echo .
cd c:\Scripts
echo Synchronizing Foo
robocopy "c:\Users\owner\documents\Foo" "\\avalon\Bar" /mir /log:sync.log


Any ideas?

not answering directly to your question, but have you seen this?

Yes, I have seen that. But, as you said, it doesn't answer my question.

By any chance, those few files that get re-copied, do they change in some way on a regular basis? Sounds like Robocopy sees them as being written to again, thus needing to re-copy them.

No, as I said in the first post I simply run the bat file and then run it
again and I notice that some files are recopied. I first thought that it
might have someting to do with the archive bit, but that doesn't seem to be
the case upon further inspection. It appears to do no harm, I just wondered
if anyone knew why some files are recopied.

I suspect that some files are locked because vista is reading them, and
robocopy "chokes" on those and aborts the procedure,
the first time around.

I have seen that with vista its much harder to unlock files than with xp...
I use a program called unlocker, but it cant do all vista files as it could
wo with xp.

Vista has better security... so good that it doesn't let YOU do what you
want with your files.. LOL

vista sucks..

news:OSQEJjBGJHA.1372@xxxxxxIs it copying the other way though? Is it mirroring back to the original
folder? If it is, it could be doing that as the Modified Dates on the new
copies are later than the originals.

I never use the /MIR switch, as it is too basic. Does it even cater for
newer file versions? If not, you fail to back up valuable data. I use
XXCOPY now a lot more, as it has more options, and can copy over File
Created, Modified and Last Accessed timestamps on files, and all three
timestamps on folders too. The free version prompts you though, so I still
use Robocopy a lot on all scheduled scripting.

That Unlocker thing sucks, is it requires backup and debug privileges, so
can only be run as administrator, in XP, or you have to seriously weaken
security to give user accounts those privileges (massive no-no). It might
be handy for newbies, but that way of using the computer would lead to bad
security and being affected by malware. That is the whole reason UAC came
about.

The documentation says that /mir is equivalent to /E /PURGE. It is a
one-way copy. In fact, I can run the bat file n times successively and it
still copies the same few files everytime. I am really interested in why
this is. I keep telling myself that it must be something simple.
