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. |
