Name
Type in a backup device name.
Device type and physical name can be defined only on creating a new backup device.
A logical backup device is an optional, user-defined name that points to a specific physical backup device (a disk file or tape drive). A logical backup device lets you use indirection when referencing the corresponding physical backup device.
Specify the type of the logical device: File or Tape.
If you have selected File then specify the full path of the file.
If you have selected Tape then select a tape drive that is not already associated with another backup device. If no such tape drives are available, the Tape option is inactive.
