Amazing that you had so much luck with robocopy ...

It did not surprise me, that it failed on me ...

Below 2 test cases: one using tar (success), the other using robocopy (failure).

(no worries: I will use tar)

Best regards,

Henri

Would you mind to keep the mail threading intact and reply to the issue
rather than creating a new thread?  It's a bit puzzeling and not easy
to follow for people looking for solutions.  Thank you.

Hmm, weird.  I used it successfully to copy complete Cygwin
installations from one machine to another.

ROBOCOPY is very reliable and it's actually what I use to have folks
"install" Cygwin on our enterprise systems (i.e. I setup a master
replica of the install and they ROBOCOPY it down to their machines).
It works without fail unless they have a files in use.  If you throw
in /R:0, do you see any other files with access denied?  Might be a
good datapoint to confirm it's everything and not something specify
about bash_history.

:-) one has to add the /B option to your invocation of robocopy ...

From robocopy /?
...
::
:: Copy options :
::
...
                 /B :: copy files in Backup mode. <==== SeBackup privilege ?????

Corinna, you are the expert !!!!! Your privilege to explain all this :-)

As the tar command was up to the job, I started to think ...

At some time in past, Corinna told this forum that Cygwin enabled the
SeBackup and SeRestore privileges ...

As I remembered that, I decided to take a second look at the output of
robocopy /?

See my reply to Corinna's reaction.
