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

Note (1): The advantage of this approach is that the two sets of data are always synchronized.

Note (2): 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.
