Managing Replication

Replication copies NAS volume data from the local (source) FluidFS cluster to a different NAS volume on the local FluidFS cluster or to a remote (target) FluidFS cluster.

The following figure shows an overview of remote replication between NAS volumes on different FluidFS clusters.

The diagram illustrates the remote replication process between NAS volumes on different FluidFS clusters. — Figure 1. Remote Replication

The following figure shows an overview of local replication between NAS volumes on a single FluidFS cluster or to a different NAS volume on the local FluidFS cluster.

The diagram illustrates the local replication process between NAS volumes on a single FluidFS cluster. — Figure 2. Local Replication

Replication can be used in various scenarios to achieve different levels of data protection.


Replication Scenarios	Description
Fast backup and restore	Maintains full copies of data for protection against data loss, corruption, or user mistakes
Remote data access	Applications can access mirrored data in read-only mode, or in read-write mode if NAS volumes are promoted or cloned
Online data migration	Minimizes downtime associated with data migration
Disaster recovery	Mirrors data to remote locations for failover during a disaster

Configuring replication is a three-step process:

Add a replication partnership between two FluidFS clusters.
Add replication for a NAS volume.
Run replication on demand or schedule replication.
