MTree replication is a DD series feature that copies unique data from the production DD series MTree to the DD series MTree in the Cyber Recovery vault.
MTree replication synchronizes data between the production environment and the air-gapped Cyber Recovery vault. Immutable protection points are created in the Cyber Recovery vault. They can be used for recovery and analytics after being copied to a read/write DD series MTree.
The Cyber Recovery software controls data synchronization from the production environment to the vault environment by DD series MTree replication. After the datasets and associated MTrees to be protected by the Cyber Recovery solution are determined, replication contexts are set up between the production and vault DD series.
MTree replication is designed so that all data within an MTree is replicated securely between two DD series appliances. After the initial synchronization is completed and all data is copied to the vault DD series, each subsequent synchronization operation copies only new and changed data segments.
