Target NAS Volumes

A target NAS volume is a read-only copy of the source NAS volume that resides on the target FluidFS cluster. The target NAS volume holds identical system configuration information (quota rules, snapshot policy, security style, and so on) as the source NAS volume. You can promote target NAS volumes to recovery NAS volumes temporarily or permanently and grant clients access to recovery NAS volume data.

The following considerations apply to target NAS volumes:

• Unlike source NAS volumes, you cannot create snapshots of target NAS volumes.
• The target FluidFS cluster must have enough free space to store the target NAS volumes.
• The system retains only the current replica of the source NAS volumes. To roll back to a previous point in time, you must use snapshots.
• You can either replicate the source NAS volume to an existing NAS volume or to a new target NAS volume. If you replicate to an existing NAS volume, the NAS volume must not contain any data you want to retain. Any data residing on the NAS volume will be overwritten and cannot be recovered.
• Target NAS volumes count toward the total number of NAS volumes in the FluidFS cluster.
