MongoDB Replication

The data replication is the process by which the data is copy to multiple locations (Different computers or servers) to improve the availability of data. The Replication means synchronization of data at multiple servers.its also provides the facility of fault tolerance in case of failure because of data at multiple sites. The Replication provides redundancy and increases the availability of data. The change made in one replication should and will reflect all other replicas. The Replication enables many users to work with a local copy of the database and manage backup recovery and disaster management.
