There are many backups programs - some free and some not....look at this link and also look at the editors and user ratings on them. Also observe if they are freeware or shareware

I want backup all my data including operating system.
What software do you recommend me for backup?
I would be really grateful to whoever can give me a free software to do this
In other words I want to make a copy of my drive "C" for recovering of the current state in case of necessity.
I would be really grateful to whoever can give me an idea of free software to do this.
Thank you very much.
