I use SuperDuper, similar to CCC.
I use it to create bootable backups. It has the ability to do smart copy, replacing only what has changed.

I've used CCC for heaps of clones, including bootable clones, and it's worked faultlessly every time. Highly recommended 
Different people like different things. And some people keep a clone and use Time Machine as well.
It's good to have a backup of your computer that is not attached to the computer for the rare issue that could affect all the disks on the computer. This includes things like power issues, but then again you do have your computer on a decent UPS right? Or you could run in the also rare case of two disks failing at the same time.
I have a backup on the shelf and Time Machine.
I had an issue with kernel panics a few months back where the machine ran fine for months and months, then one day the KPs started....wouldn't even boot except for safe mode.
Tried using Time Machine to go back a day, a week, a month and whatever it was still KP'd the machine.
Finally pulled my CCC clone off the shelf and booted fine with it...then cloned it back to the internal drive.....restored data from my TM backup and was back in business.
You can create a bootable clone with Carbon Copy Cloner, then keep that clone up to date with manual or automatic scheduled incremental backups.
After the initial clone backup, select "Incremental backup of selected items" for all subsequent backups.

I don't see this bzvol on the left side and definetly didn't see the increment backup ,

Forget the "bzvol" on the left side. That just happened to be in the screen shot that I found. On the right side on yours, it shows "My custom settings 1" because the default settings have been modified. However, your custom settings show the following:
This means it's an incremental backup. It doesn't backup everything again; it only backs up what has changed since the last backup.
