Diagnosing the problem

  • Verify the level of the Tivoli Storage Manager client. It must be at minimum level for both the backup and restore operations.
  • Verify that the backup completed without errors
  • Verify that the "TESTFLAG SKIPVSSASR" option is not specified in the client option file (dsm.opt) or specified as a command parameter with "-TESTFLAG=SKIPVSSASR"
  • Verify whether the Windows 2008 R2 machine firmware interface is based on Extensible Firmware Interface (EFI) rather than Basic Input/Output System (BIOS).

Resolving the problem

In this case, the Windows machine was based on EFI, which is an unsupported environment with Tivoli Storage Manager V6.x clients.
