About media devices
The Backup Manager uses the Device Query Interface (DQI)
to determine what media devices are available on your system
and display their names wherever you are prompted
to select a media device. You can also use a device
that is not supported in the DQI by deleting the
current entry in the ``Media Device'' field and entering the
desired device file (for example, /dev/rct0).
NOTE:
To permanently add a non-DQI device to the list of default
devices, see
``Setting the default media values''.
Depending on the hardware you have installed,
the Backup Manager supports these media devices by default:

To set a specific media device to be the default, see
``Setting the default backup device''.
For each media device on your system,
the Backup Manager uses default values for the
block and volume sizes.
To change these default values, see
``Setting the default media values''.
NOTE:
Although the DQI automatically senses
the type of media on your system,
in some cases the DQI cannot automatically sense the capacity
(volume size) of the drive,
and so sets the volume size to 0.
To use the Backup Manager to back up such a filesystem,
you must first set the volume size for the devices on your system.
See
``Setting the default media values''
for more information.
