10.2. Replicated Volumes vs Geo-replication

The following table lists the differences between replicated volumes and geo-replication:
Replicated Volumes Geo-replication
Mirrors data across bricks within one trusted storage pool. Mirrors data across geographically distributed trusted storage pools.
Provides high-availability. Provides back-ups of data for disaster recovery.
Synchronous replication: each and every file operation is applied to all the bricks. Asynchronous replication: checks for changes in files periodically, and syncs them on detecting differences.
