Shadow copy is not breakable for read/write

Question

Dear everybody,

I need to create a shadow copy for read/write. I am trying to do this using Windows SDK vshadow.exe and vssadmin.exe tools. These are the commands that I execute respectively:

vshadow -p -rw -script=c:\cmd\SETVAR1.cmd d:

vshadow -el={451c1ab8-0de8-4592-95ce-5795ef43abbd},x:

vshadow -bw={d3165e77-b7f8-4580-a09f-8054c450a6b3}

All is good up to the second command. The shadow copy is exposed but it is read-only. When I execute the third command, I get the following error:

And thus it remains read-only. VSS_E_PROVIDER_VETO.txtI added the /tracing option but it is not informative at all and leads to absolutely nowhere. I have included its output as an attachment. In addition, I have included the original output of the execution of the first command if it can be of any help.

I really appreciate your help in advance.

Regards,

Ali

Hi amomen,

Thanks for your post. Please mention that the -b and -bw command-line options are mutually exclusive and cannot be combined with other command-line options.

Therefore, kindly use -p and -bw separately and see if it take effect.
