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. In data replication the same data is stored on multiple storage devices. Unlike Backup software Data Replication refers to active real-time replication which may be at a disk-level, file-level or database level. Disaster recovery (DR) is a set of policies and processes to restore the systems to normal use by recovering data from a replicated copy and thereby meet the business continuity goals.
