Attempting to install the Copy Services VSS Integration package fails with an error indicating that the Data Protection for Exchange is not installed. However the Data Protection Exchange software is indeed installed and working.
The following error is seen when attempting the install:
Installation of IBM TSM for Copy Svcs MS Exchange VSS Integration Module requires IBM Tivoli Storage Manager for Mail - MS Exchange
This problem for the installation is due to the Tivoli Storage Manager Copy Services code looking for an older version of the Data Protection for Exchange product and does not recognize the newer release that is installed.
Resolving the problem
When using the Data Protection for Exchange to perform a VSS backup of an Exchange 2007 or Exchange 2003 Server, it is necessary to have a license to enable the VSS capability. The license can be put in place by installing the FlashCopy Manager software or by installing the Copy Services module.
However, when attempting to install the VSS Integration Module package, with Exchange 6.1.x this fails with the error:
To work around this problem, it is possible to manually copy the license file that is needed.
The installation attempt should have extracted the package to the TEMP location on the machine.
Copy the ...\TDPExchange\x32\plugin\program files\Tivoli\TSM\TDPExchange\acsexc.lic file to the Data Protection Exchange installation directory (\Program Files\Tivoli\TSM\TDPExchange by default).
After this is in place, the VSS functions should be available (not grayed out) when you launch the Data Protection for Exchange GUI.
It will also be necessary to ensure that the configuration is in place for the VSS backups (as listed in the manual).
