Replication in storage refers to?

Replication in storage is about duplicating data to a secondary array or another site so you can fail over quickly if the primary location is unavailable, which supports disaster recovery and high availability. It can be synchronous, where writes are confirmed at both locations, or asynchronous, where replication happens with a delay. This is distinct from backups, which are protection copies kept for recovery from data loss but aren’t necessarily used for immediate failover. The idea of allocating storage on demand is about provisioning space as data is written, not moving data to another site. Deduplication reduces the amount of stored data by removing duplicates, which saves space but doesn’t create a second copy for failover.
