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

Yes, indeed. The obvious logical next step is to combine the imaging and
compression into a single command.

I didn't go that far because I surmised that explaining the individual
parts would be helpful. However, pipes and redirection provide wonderful
opportunities to simplify tasks to a single command, and this is a
straight forward example.

I would caution that the bunzip will probably take a lot of time.
Indeed, dd will take quite some time, but the bunzip even more. You
might want to do this overnight.
