storage backup proxy add (NFS)

failover-peer	Performs the command on the failover peer of the current appliance. If the failover peer is unavailable, the changed configuration is automatically applied when the appliance returns to service. You can run failover-peer commands only on a Core appliance in ActiveSolo failover state.
<proxy-id>	Proxy identifier.
hostname <proxy-hostname>	Specifies the proxy hostname of the proxy host.
hostname <ip-address>	Specifies the IP address of the proxy host.
type vmware_esxi	Specifies the VMware ESXi compute type.
username <name>	Specifies the username for the backup proxy.
password <password>	Specifies the password for the proxy user.
acccess_group <access-group>	Specifies the access group for the backup proxy. n NetApp - Specify the export policy name containing the access rule for the proxy ESXi server. n EMC Isilon - Specify a comma-separated list of data interface IP addresses or a hostname for the proxy server. The username and password credentials must have access to SSH because snapshot communication occurs through this channel.

The Core integrates with the snapshot capabilities of the storage array. Once the snapshot reaches the data center, the Core triggers the application-consistent snapshot on the supported array and automatically mounts the snapshot to a proxy host. The backup software on the storage array can then perform the backups through the proxy host in the data center.
