Re: shell scripts

[Casey Boone <caseyboone@gmail.com>]

try excluding dev, i think you are hitting something like /dev/random or
/dev/zero

also use -v to make tar it more verbose so you can see what file it is
tar-ing up

lastly you can compress with tar, no need to tar then compress.  check
the man page for the -z and -j switches
