Simple script to backup all relevant partitions

[jin-eld]

Hi,

I wanted to have something simple to backup my tablet partitions, preferably one script file. So I put together something from your scripts and added more sanity checks.

I do not know if you need it, maybe others will find it useful as well: http://www.deadlock.dhs.org/jin/ventos/simpledump.sh

Sorry for the "feature request", I did not really know how to share it.

Kind regards, Jin
