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).
Depending on the hardware you have installed, the Backup Manager supports these media devices by default:
|1/4-inch Cartridge Tape Drive 0||Primary cartridge tape||/dev/rct0|
|1.44MB 3.5in Floppy Drive 0||Primary 1.44MB floppy||/dev/rfd0135ds18|
|1.44MB 3.5in Floppy Drive 1||Secondary 1.44MB floppy||/dev/rfd1135ds18|
|720KB 3.5in Floppy Drive 0||Primary 720KB floppy||/dev/rfd0135ds9|
|720KB 3.5in Floppy Drive 1||Secondary 720KB floppy||/dev/rfd1135ds9|
|360KB 5.25in Floppy Drive 0||Primary 360KB floppy||/dev/rfd048|
|360KB 5.25in Floppy Drive 1||Secondary 360KB floppy||/dev/rfd148|
|1.2MB 5.25in Floppy Drive 0||Primary 1.2MB floppy||/dev/rfd096|
|1.2MB 5.25in Floppy Drive 1||Secondary 1.2MB floppy||/dev/rfd196|
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''.
