Time to Restore Business Operations in the context of Business Continuity Management

Related Terms: Synchronous, Asynchronous Replication, Data Protection/Recovery Strategy - Category.

Note: The advantage of this approach is that the two sets of data are always synchronized. The disadvantage is that if the distance between the two storage disks is substantial, the replication process can take a long time and hence, slows down the application writing the data.
