Ubuntu – Backup whole OS


I have to format my entire disk and reinstall Ubuntu.

I have installed a lot of software on my current system. And I will have to reinstall all those updates, drivers and applications too.

Is there any way I can make an .iso image of my installed Ubuntu along with all the software, preferences, drivers etc in it ?

Is there any way I can back up my whole OS along with all its
software, drives, updates and all ?
