Share replication

Redundancy options of a pool operate at the single appliance level. While this reduces the risk of data loss from bad disks, it does no good if the entire appliance fails. To mitigate and distribute this risk, Shares can be replicated to other Rockstor appliances.

Replicate shares to other Rockstor appliances

Shares from one Rockstor appliance can be replicated to others at scheduled frequencies. Replication frequency is in seconds and can be as little as 60 seconds. The appliance that hosts the replica is called a target appliance. At least one target appliance must be added before setting up replication for shares. See Adding a remote Rockstor appliance for more details.

In the webui, click on the Storage tab to enter the main Storage view. Now click on Replication in the left sidebar to enter Replication view. Click on Add Replication Task button and a form will be displayed. Submit the form as shown below.

Note that a pool must already exist on the target appliance to host the replica of the share.
