storage backup group add

[failover-peer] storage backup group add <group-id> server-id <server-id> policy-id <policy-id> {membership all [exclude <members>] | membership selected members <members>} [max-history <max-history-number>] [quiesce-vm-list <quiesce-vm-list>]

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.
<group-id>	Protection group identifier.
server-id <server-id>	Specifies the Edge server identifier. Identifiers are case sensitive.
policy-id <policy-id>	Specifies the backup policy identifier.
membership all	Specifies all members in the backup protection group.
exclude <members>	Excludes the specified members.
membership selected members <members>	Specifies selected members in a backup protection group.
max-history <max-history-number>	Specifies the maximum history of protection operations maintained for the protection group. The default is 5.
quiesce-vm-list <quiesce-vm-list>	Specifies the list of VMs that will be quiesced into a state suitable for backups. This option is disabled by default.

The Core uses the protection group to map the servers, VMs, and LUNs that are being protected. Each protection group contains the information associated with the server being protected, backup proxy host, and backup protection policy.
