Local Tape or Diskette Drive

Typically, dump-file specifies a raw device file for a tape or diskette drive. When ufsdump writes to an output device, it creates a single backup file which may span multiple tapes or diskettes.

You specify the tape or diskette device on your system using a device abbreviation. The first device is always 0. For example, if you have a SCSI tape controller and one QIC-24 tape drive that uses medium-density formatting, use this device name:

/dev/rmt/0m

When you specify a tape device name, you can also type the letter "-n" at the end of the name to indicate that the tape drive should not rewind after the backup is completed. For example:

/dev/rmt/0mn

Use the "no-rewind" option if you want to put more than one file onto the tape. If you run out of space during a backup, the tape does not rewind before ufsdump asks for a new tape. See "Backup Device Names" for a complete description of device naming conventions.
