Requirements for Exchange off-host backups
Note the following requirements and operational notes for off-host backups:
Exchange does not need to be installed on the off-host client.
For consistency checks of Exchange with the Microsoft consistency check API, Veritas recommends that you install the Exchange System Management Tools on the alternate client. Then restart the Exchange Server. If you choose not to install the Exchange System Management Tools on an Exchange alternate client, you must install the VC9 run-time DLLs. These DLLs can be downloaded from Microsoft x64 VC9 download page:
