[-prefix <text>] - Snapshot Copy Name Prefix for Schedule This option specifies the prefix with which Snapshot copies will be created for the added schedule. Every schedule has only one prefix. Once a prefix gets associated with a schedule, you cannot update the prefix. If some prefix is already associated with the schedule and you do not specify this parameter, then the previously defined prefix is used. The command fails if you try to update an existing prefix for a schedule. If no prefix is associated with the schedule and you do not specify this parameter, then schedule name is be used as the prefix.
