Best Practices for Using Volume Shadow Copy Service with Exchange Server 2003

Microsoft® Exchange Server 2003 uses the Volume Shadow Copy Service (VSS) that is included in the Microsoft Windows Server™ 2003 operating system to take volume shadow copies of one or more of your Exchange Server 2003 databases. VSS, if deployed correctly, enables you to recover computers running Exchange Server 2003 within minutes, regardless of the size of your Exchange Server 2003 database. Because many VSS strategies are available, you must understand and test the capacity, performance, and recovery implications of the solutions in order to ensure that you have the data that you need to succeed in your deployment, and you must ensure that any potential solution is operating within the VSS framework. This article provides information about choosing, testing, deploying, and monitoring a VSS solution for Exchange Server 2003.
