	I just went through much of this with my Lego USB Tower IR transceiver.
The basic idea is: you plug in the drive, and the necessary commands
execute to create a file with a very long name in /sys.  Then, two more
files come into play.  They are /etc/udev/permissions.d/*
and /etc/udev/rules.d/*.  The permissions.d entry (which can live in any
one of several files in that directory) looks like:

sd*:root:disk:0660

the first arg (separated by colons) is a shell-glob that matches the
name of the device.  The next two are the owner user and group, and the
third is the octal permissions (rw-rw---- in this case).

	A simple rules.d entry looks like this:

KERNEL="legousbtower*", NAME="usb/%k"

shamelessly stolen off the 'net.  There are so many variables (the
KERNEL and NAME strings above, for instance) that I can't possibly
include them all in this missive.  At any rate, the rules file should
point you toward finding how to name your backup USB drive to a constant
entry in /dev.

	Hope this helps!

	See <a  rel="nofollow" href="http://www.linuxjournal.com/article/7316";>http://www.linuxjournal.com/article/7316</a> for a better explanation
than the above.
