backup på Image

Hi
Which tool do you use to make a full backup (nfi) file of your Dm800Hd Se box ?
I would like to make such backup now when all my settings and plugins is installed and working
to be used later if necessary.

I have Heard about the following proz, but I do nor know were to find them nor to intall them

DFalsz v 10.2 sim a8p full backup dowload and DFalsz v 3.3 sim 2.10 backup full

Any one that can inform if these are the best Tools to make a full backup and were I can find them
also how to install them into the box.

The backup file (nfi file) I would like to save on my computers drive.
