Re: [orca-list] Does anyone know of a program for backing upa computer that works with orca?

I may have asked this some time ago but don't remember the outcome.  If 
I use dd to backup say a 40GB partition but decide to restore it to a 
new larger hard drive and have room for larger partitions, how can I 
restore this original image to that newer bigger partition? I would 
think that image would force the target partition to the original 40GB 
size.  I'm looking for an easy way to migrate my system from one older 
drive to a new larger one.
