Configuration directives for the Autochanger resource. Every directive is listed; value types and defaults are noted where the source provides them.
Changer Command
Section titled “Changer Command”Changer Command = <name-string>
The <name-string> specifies an external program to be called that will automatically change volumes as required by NGBackup. Most frequently, you will specify the NGBackup supplied mtx-changer script as follows. If it is specified here, it need not be specified in the Device resource. If it is also specified in the Device resource, it will take precedence over the one specified in the Autochanger resource.

The specified <name-string> gives the system file name of the autochanger device name. If specified in this resource, the Changer Device name is not needed in the Device resource.
