Data Replication vs. Data Mirroring

Data replication and data mirroring are both methods used in managing and safeguarding data, particularly in the context of databases and storage systems. While they share similarities in creating copies of data, they serve different purposes and have distinct operational characteristics.

Data Replication


  • Data Replication involves copying data from one location to another. The replication can be synchronous or asynchronous.


  • Asynchronous/Synchronous: Data replication can be done in real-time (synchronous) or with some delay (asynchronous).
