Adds volumes to the set of volumes that are to be shadow copied, or adds aliases to the alias environment. If used without subcommands, add lists the current volumes and aliases.


Aliases are not added to the alias environment until the shadow copy is created. Aliases that you need immediately should be added by using add alias.

For examples of how to use this command, see Examples.


add volume <Volume> [provider <ProviderID>] 
add alias <AliasName> <AliasValue>
