   You'd need something to the effect of:   
     dd if=/the/device (NO if=) [...] | gzip > /mnt/sdb1/images/xx.img.gz   
      
   restore would be:   
      
     gunzip -c xx.img.gz | dd (NO if=) of=/dev/whatever [...]   
      
   But that's just from a quick spin on the corresponding manpages for the   
   commands themselves.  I'd test it on something small (e.g. a USB stick   
   image) before doing it on the main drive.
