How does data replication improve disaster recovery?

Can you explain how data replication helps in disaster recovery?

Sure! Data replication involves copying data from one location to another, ensuring that a backup is available in case of a disaster.

What types of data replication are there?

There are several types, including synchronous, asynchronous, and near-synchronous replication, each with its own use cases.

How does synchronous replication work?

In synchronous replication, data is copied to the backup location in real-time, ensuring both sites have the same data at all times.

Are there any downsides to using data replication?

Yes, it can be costly and may introduce latency, especially with synchronous replication, as it requires constant communication between sites.
