Use the with dumpvolume = volume_name option to specify the volume name.
dump database and dump transaction write the volume name to the SQL tape label. load database and load transaction check the label. If the wrong volume is loaded, Backup Server generates an error message.
You can specify a volume name for each dump device. You can also specify a volume name in the with clause for all devices. Volume names specified for individual devices take precedence over those specified in the with clause.
