Using backup and restoration procedures for site disaster recovery as described in the Microsoft Office Communications Server 2007 R2 documentation library topic Backup and Restoration, can entail some downtime for users.

This white paper describes a site resiliency solution for Office Communications Server 2007 R2. The solution includes an Enterprise pool that spans two geographically separate sites. The solution provides a failover mechanism between the two sites to ensure that Office Communications Server functionality such as instant messaging, presence, and conferencing remains available even if one of the sites becomes unavailable.
