What compression type to use for disk image files

Hello all

I was wondering if a more experienced user than me could give a recommendation as to which compression format I should use to compress an image I made of my / partition. I used dd to make the image file.
For me, (de)compression time is more important than compression ratio (size), but I'm of course looking for a good blend of both

Thanks for any advice

Re: What compression type to use for disk image files

If you have a multicore processor, use pigz instead of gzip etc. Start with this app and only after you're not happy with it, look for one that's faster / compresses better.

BTW, do you have a lot of incompressible data in there? Movies, pics, music and already compressed files won't compress any more.
