DISASTER RECOVERY is simply an xml file that contains all system related information, line , HDD information, partition information, and so on. This is required for bare metal recovery only. Refer the NetWorker Administrator guide for more details on this saveset.

Thanks. That of the XML does not explain why sometimes it saves a \\?\VOLUME{something}.

The \\?\VOLUME is the system partition on your OS.

Hi Noel,

The XML file is the VSS BCD )Backup Component Document) which, as crazyrob explained, contains al the information about the files to be backed up by the specific writers, in this case the System Writer.

You can find out the volumes you have by running:

vssadmin list volumes, and you will see that  the "name" for each of them is something like you said:

\\?\Volume{240a50e8-fe30-11e3-8550-806e6f6e6963}\

Also, to know exactly the files to be backed up, you can start diskshadow and logging all outputs to a file by starting a Command Prompt and launching this command:

diskshadow /l c:\diskshadow.out

From the diskshadow prompt, issue the following commands:

reset
list writers
list writers status
list writers metadata
list writers detailed
list providers
exit

The output of all the above commands will be found in c:\diskshadow.out. The output can use useful to see the list of files which are reported by the VSS writers to be included and excluded by the backup.

Thank you,

Carlos
