You may find what I do useful.  Getting it to what you want for the /backups
could be a simple exercise for you from here.

%pre
#!/bin/sh

hds=`awk '{print $4}' < /proc/partitions |grep sd[a-z]$`

for file in /proc/ide/h*
do
  mymedia=`cat $file/media`
  if [ $mymedia == "disk" ] ; then
      hds="$hds `basename $file`"
  fi
done

set $hds
numhd=`echo $#`

if [ $numhd -le "1" ] ; then
  #1 drive
  echo "#partitioning scheme generated in %pre for 1 drive" >
/tmp/part-include
  echo "zerombr yes" >> /tmp/part-include
  echo "clearpart --all --initlabel" >> /tmp/part-include
  echo "part /boot --fstype ext3 --size 50" >> /tmp/part-include
  echo "part swap --recommended" >> /tmp/part-include
  echo "part / --fstype ext3 --size 1 --grow" >> /tmp/part-include
