I have recently bought Dell Vostro 3550( Windows 7 Ultimate, 32 bit).

I want to create a backup image of my system(Operating system + Drivers), so that, in future, if something goes wrong with operating system , I'll be able to restore all the Windows and drivers using the backup image file.

There are 2 options,  in "Dell Backup and Recovery Manager" software for doing this.

1. Backup System.
2. Dell Recovery Tools.

Which option should I use?

What is the difference between those two options?

Thank you, for any help.
