Workaround

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

1.   On the Backup Exec server, enable the following registry value (Use VMDK Remote Mount =1):

      Key location:  HKEY_LOCAL_MACHINE\SOFTWARE\veritas\Backup Exec For Windows\Backup Exec\Engine\VMware Agent
      DWORD value:  Use VMDK Remote Mount
      Set the value to 1.

2.   Create or edit the existing backup job for the VMWare guest machines to DISABLE the Delayed Catalog  feature.  In the edit job options, under ‘Delayed Catalog’ tab, choose ‘Do not run a delayed catalog operation’.
