Disaster Recovery (DR) plans are becoming a key part of a company's overall IT planning process to ensure continuous availability of the company's critical infrastructure at all times. A major component of these plans involves protecting business-critical data through backups and data replication.

Such replication and backup processes may occur between data centers, branch and home offices, or primary and backup sites. A successful business continuity/DR plan has two key components at its core: a solid replication product to manage replication processes, and an effective and efficient Wide Area Network (WAN) that enables those processes to be accomplished successfully.
