10. NAS Replication

Block-based NAS replication is a feature that uses snapshot technology

in the PowerVault NX3500 file system. Replication is volume-level and

can be used to replicate volumes on the same or another PowerVault

NX3500 system. After the initial replication, changes to the stored data

are recorded to the target volume.

When replicating a volume to another PowerVault NX3500 system, you

must set up the other system as a replication partner. Once a partner

relationship is established, replication is bi-directional: one system can

hold target volumes for the other system as well as source volumes that

are replicated to the other system. You can set up replication policies

to run on various schedules as well as on demand.
