What are the differences between synchronous and asynchronous replication?

What are the differences between synchronous and asynchronous replication?

Synchronous replication ensures data is written to both the primary and secondary storage simultaneously, while asynchronous replication allows data to be written to the primary storage first, with the secondary storage updated later.

What are the advantages of using synchronous replication?

The main advantages of synchronous replication include data consistency, reduced data loss risk, and real-time data availability across locations.

Are there any downsides to synchronous replication?

Yes, synchronous replication can introduce latency, as the system waits for confirmation from the secondary storage before proceeding. This can affect performance.

When should I consider using asynchronous replication instead?

Asynchronous replication is ideal for scenarios where performance is critical, and some data loss is acceptable, such as in disaster recovery setups.
