I don't see any obvious problem with your command line. I believe /COPYALL
is redundant when using /MIR and should be dropped. I suggest if what you
want is to mirror the directories, start by testing /MIR as your key command
in conjunction with the "/Z, /NP, /R:4, or W:5" in combinations to see what
may conflict. I would consider dropping the /Z however.
(Per MS DOC Note If you use /Z, /B, or /ZB, this can decrease Robocopy
performance and throughput significantly, as these options involve extra
overhead. These options are therefore only recommended when experience
indicates you really need them.)
Robocopy can be difficult to troubleshoot. I've seen subtle errors relating
to conflicting commands or the sequence of parameters on the command line.
I take it no errors are logged or displayed? How does the command fail?
A manual of sorts for robocopy (robocopy.doc) is bundled with the Windows
Server 2003 Resource Kit Tools. (I don't think the current version is
It has some info on exit codes that might be of some help.
