Shadow Copy Components cannot be added to backup jobs

Our backup is not seeing our Shadow Copy Components anymore and I'm not sure why.  We have a 'G:' drive shown in the server's disk management that previous was accessable through Backup Exec's Shadow Copy Components but now that option isn't available.  This is the entire exception we are receiving:

Resource \\SERVERNAME.DOMAIN.local\Shadow?Copy?Components was found in the previous instance of this job, but it is not present in this job.

I've attempted to create a new backup job, but the 'G:' drive or Shadow Copy Components are not available within the selection details.  One thing I've noticed is that the service 'Volume Shadow Copy' is not running and set to Manual.  I'm not familiar with this service and how/if it relates to Backup Exec backup jobs.

How do we get back access to our Shadow Copy Components again?

Thanks in advance,

    Sorry for the delayed response.  We have found a solution to our issue.  Without DFS configured, we decided to backup the specific cluster servername.  Unfortunately, that failed as well because I wasn't aware that the Agent for Windows license wasn't installed properly.  Once we properly installed the agent, the backup worked without using Shadow Component Copy.  

    Thanks again for your help.

    Assuming the server you are referring with G: volume is different than BE media server and perhaps running DFSR, run the following command from command prompt on the that server:

    VSSADMIN LIST WRITERS

    Confirm if DFSR writer is listed in the output received. If it's not listed, just reboot this server and run the above command and check if now DFSR writer is listed. If it's now listed, then check the job selection and now Shadow Copy Components should be visible.

    The service 'Volume Shadow Copy' is set manual by default and does not run unless invoked (during snapshot backups using VSS).

      Thank you for your quick reply!

      The 'G:' drive is different from a BE media server.  The DFS Replication Service is currently running on this server.

      I checked the writers to find 'DFS Replication service writer'.  I'm assuming this is the one you are referring to?  It shows with no errors and Stable.

      After checking that, I went back to the backup job and the Shadow Copy Component was still not available.  That is including a new backup job as well.

      Let me know if I may have missed something.

        You must be using BE 2014 as noticed in TAG. If this was an upgrade to BE 2104, can you also confirm if the Remote Agent on the DFSR server is updated to BE 2014 and not running a previous version. This was a known problem in past with previous BE version (000020111) and was fixed with BE 2014 and so if remote agent is not updated, may still see this issue.
