I was wondering if anyone could better explain the /Z and /B flags and
how they work exactly? I understand that they help robocopy restart
where it left off in case of a networking issue, but I guess I'm
looking to see if it is causing the issue I am seeing.

I am robocopying file shares from one server to another. While doing
these copies, I always use the /ZB flag. I have had issues from time
to time that require that I get folders copied over before robocopy
gets to them. So, I will start a second robocopy that copies the
files that the first hasn't got to yet. However, I have seen that
once the first robocopy does get there, it copies the files again like
they aren't already there.

Does anyone know if this is the result of using the /Z or /B flag or
is this just how robocopy works?

Thanks.

Best to check robocopy.doc. It comes with the Windows Resource Kit.
For a short time you can also get it from here:

Thanks, I think that had most of the information I needed. I still
didn't quiet figure out if that if the /zb flag was causing me the
problem I described, but to improve performance I pulled it out
anyhow.

Thanks again.
