Dell FluidFS NAS Solutions Administrator's Guide

Replication is used in various scenarios to achieve different levels of data protection. Some of these include:

Fast backup and restore

Maintain full copies of data for protection against data loss, corruption, or user mistakes.

Disaster recovery

Mirror data to remote locations for failover.

Remote data access

Applications can access mirrored data in read-only or read-write mode.

Online data migration

Minimize downtime associated with data migration.

Replication leverages the snapshot technology in the NAS cluster solution file system. After the first replication, only deltas are replicated. This allows for faster replication and efficient use of the processor cycles. It also saves on storage space while keeping data consistent.

Replication is volume based and can be used to replicate volumes on the same NAS appliance or a volume on another NAS appliance. When replicating a volume to another NAS appliance, the other NAS appliance must be setup as a replication partner.
