Problem with VSS on a physical Windows Server

Hi,

I am adding a physical Windows Server 2016machine as a first client in a new Windows Policy (This is a new NetBackup installation, version 8.1.1). The backups fail with status 69, the log says (some host names edited throughout):

- "vssadmin list writers" on the client shows "No errors" and "stable" for all writers

- The backup stores about 6GB (of about 56GB on the disk) of data, so at least something must be working

- A VSS backup using Windows Backup succeeded

- I have tried all available options for the VSS provider type, the error is always the same

- During the (NetBackup) backup, "vssadmin list shadows" shows an active shadow copy that did not exists before the backup:

Any ideas anybody?

      Spot on, J_MCCOLL! Thank you. Even though the large disks were excluded in the backup policy, they were apparently still scanned and the backup failed. I changed the registry parameter and the backup succeeded.

      What is the Backup Selection in your policy?


      ALL_LOCAL_DRIVES, with some NTFS mount points excluded in the host properties. The article supplied by J_MCCOLL had the solution, though.
