Database replication is the frequent electronic copying of data from a database in one computer or server to a database in another so that all users share the same level of information
Replication in computing involves sharing information so as to ensure consistency between redundant resources, such as software or hardware components, to improve reliability, fault-tolerance, or accessibility.
Data Replication is the process of storing data in more than one site or node. It is useful in improving the availability of data.
