GNUtar can be told to do devices.  However, when you restore you
may or may not want the devices back, since the reason you are restoring
may be that all or part of the original machine is no longer working.
Since they usually don't change often it is a good idea to backup
/dev by itself and omit it from backups of the files.  If the machine
has a floppy disk, you can use cpio to save them there, and restore
only if the same kernel is restored back to the same or an identical
machine.
