Note the following requirements and operational notes for off-host backups:

• (Exchange 2007) VxVM 5.0 or later is required for off-host backups that use the Storage Foundations for Windows (SFW) VSS provider. For Windows 2008 and later and Windows 2008 R2 and later, VxVM 5.0 is required for local and off-host snapshot backups.

• (Exchange 2007) To successfully perform backups with the SFW VSS provider for VxVM 5.0, you must apply the following hotfixes. Apply the hotfixes on the hosts where a snapshot backup occurs.

  Note:

  These hotfixes are included in SFW/SFW-HA 5.1 and are not required if you have that version.

• The Exchange Server does not need to be installed on the off-host client.

• (Exchange 2007 and later) For consistency checks of Exchange with the Microsoft consistency check API, Symantec 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 2010 alternate client, you must install the VC9 runtime DLLs. These DLLs can be downloaded from Microsoft x64 VC9 download page:
