ARKEIA - CAN YOU TELL ME IF I BACKED UP PROPERLY

Hi. I downloaded the free trial of ARKEIA
http://www.arkeia.com/download/download-software

In about 10 minutes I figured it out via the web interface and believe I backed up my entire system.

It is noob, but they dont spell it anywhere in layment terms if I backed up my ENTIRE file system like a clone, including GRUB?

I did backup on my end, everything possible, which was my entire file system.

if this is what ARKEIA is for, then i probably did back everything up. it totalled about 55 gigs on my linux mint system.
