Automatically copying data between two processing systems either synchronously or asynchronously is known as what?

• A. Replication
• B. Backups
• C. Mirroring
• D. Synchronization

Answer: (A)

Replication is the automatic copying of data from one processing system to another to keep them in sync. It can happen in real time (synchronous) where changes are written to the copy as they occur, or with a delay (asynchronous), where updates are sent after the write completes. This arrangement supports high availability and disaster recovery by ensuring a nearby or duplicate system has an up-to-date copy of the data. Backups, by contrast, are point-in-time copies kept for recovery from data loss and are not typically kept perfectly in sync with the primary. Mirroring is often used to describe a very close form of replication that creates an exact copy for redundancy, but replication is the broader term for automatically propagating data between systems. Synchronization is a general concept of aligning data or state, whereas replication specifically describes the ongoing copying process between systems.
