Hi,

   nsrsnap_vss_save -? will show on APPLICATION savesets (for example, savesets for Applications such as Exchange, SQL, SharePoint and Hyper-V).  It will not display savesets for file systems.  So if the host on which you run this command is a standalone server with no NMM supported applications on it (this includes a Domain Controller), the nsrsnap_vss_save -? will not list any savesets.

If this command is run on an application host such as Exchange, SQL or Sharepoint and it still does not list any savesets, then check the following:

1. If this command is being run on a cluster node then include the '-c' switch.  For example, on an Exchange CCR cluster, you would run the following command:

nsrsnap_vss_save -c physical_server_name -A NSR_VIRT_SERV=virtual_server_name -?

2.  Check and make sure that the services related to the application are running:

For example:

a. On a SQL server, the SQL server service and the SQL server writer should be in a running state.

b. On an Exchange server, the 'Exchange Information Store' service is running.

c. On a CCR cluster, using Exchange Management Console, check the Copy status of the storage group. This should be in the 'healthy' state. If it is in any other state then nsrsnap_vss_save -? will likely not show the exchange savesets.

Hi Agracci,

DFS-R replicated folders and data is backed up as file system data and is not backed up as a part of DFS-R writer in SYSTEM COMPONENTS:\ save set backup. DFS-R replicated folders and data recovery is supported to both original or alternate location. Directed recovery of DFS-R replicated folders and data is also supported.
Because DFS-R replicated folders and data is backed up as file system data, all the features supported by file system data backup and recovery are supported by DFS-R granular support.

DFS-R writer backs up only SYSVOL in a domain controller as a part of Bootable System State.
Recovery of DFS-R writer is supported only to original location as this is a part of SYSTEM COMPONENTS:\ save set. On non-domain controller, the DFS-R writer is not part of the SYSTEM COMPONENTS:\ save set.

So in this case, DFSR is not displayed as valid saveset because there is not specific saveset for it, same happens for Active Directory backup, that gets backed up as part of SYSTEM COMPONENTS:\ saveset (Snapshot based backup, granular backup of Active Directory uses different backup command and different saveset syntax).

Thank you.

Carlos.

Agracci,If you would like to retrieve more information about DFS writer you would like to use DISKSHADOW command, it will provide you information about the files and dependencies of this writer.

Example:

C:>diskshadow

DISKSHADOW>list writers detailed

This should display (take some time depending on the HW resources and the writers information, as well as the applications/writers installed/registered) all the files needed to have a consistent backup of this writer.

Small advice: change the command prompt window before running this command to have a bigger buffer size (max is 9999), or you can redirect it to a file, however if you download NMM Config Checker, and run "NMM EMC Reports", that gets installed with Config Checker, this will automatically run this command (DISKSHADOW) so you can just read the output and you will have all the information.

Thank you.

Carlos.

The simple way to redirect teh diskshadow output is that, create a text file( expample: input.txt) containing text "list writers detailed"
c:\> diskshadow /s input.txt >output.txt
it will give you a output in output.txt file.
