"dd | 7z/gzip/bzip" and "7z/gzip/bzip | dd"

[Browser_ice]

In case you have not guessed it, I am looking at a one line command to do :

1) DD or DCFLDD the whold drive into an ISO file
2) compress that output ISO file


Isn't there a way to do it all in one line like :
dd if=xxxxx bs=999 | 7z .... drive.iso.7z

and then to restore :

7z ... drive.iso.7z | dd bs=999 of=/dev/sda

In the example I use 7z because I like it. I would prefer using it over gzip, bzip, ...

Is my question too complicated or that no one knows how to do this ?

You should post this in the programming section thats where all the bash programmers are. I would love to help you but my bash skills are kind of rusty.
