The Legacy Exchange agent is supported on the following operating systems:
• Microsoft Windows 2000
• Microsoft Windows Server 2003 with Service Pack 2
• Microsoft Windows 2003 Release 2
The following versions of Microsoft Exchange Server are supported for use with the Legacy Exchange agent:
• Microsoft Exchange version 2003 with Service Pack 2
• Microsoft Exchange 2007 for Exchange store level backup only
Note: Windows Server 2008 and 2012, unlike past Windows Server releases, do not include support at the utility level for Exchange aware backups, therefore the legacy agent is not supported on these platforms. Use the Exchange VSS agent for these platforms.
The following backup agents provide full functionality, but do not capture the last master or last differential of the Exchange agent:
• Protection software for Microsoft Windows v4.x
• Protection software for Microsoft Windows Server 2008 v4.1
See About Exchange 2007/2003 backup for more information.
Caution: The circular logging option must be disabled on the Exchange Server in order to achieve successful differential backups. If circular logging has not disabled, differential backups will fail.
