A solid DR plan can evolve into disarray if content database growth is unconstrained. As a content database size increases, the speed to recover slows proportionately. In the previous sections we established the metrics for working within SharePoint limits, and reporting on sizing. Once there is a complete picture of the SharePoint farm, one can take steps to manage its growth.
Recommendation: Monitor database growth on a weekly basis. Any large growth merits a conversation with business users to understand the change in behavior. Often the growth is tied to a new use for SharePoint that can possibly be addressed with a separate dedicated content database to maintain manageable database sizes for rapid DR recovery.
