I have Windows 7 OS in my HP laptop.I bought it before about 1 year.I still didn't created the recovery discs.Actually i tried to do it.One of my friend who has done it(but in Windows Vista,not in 7),told me that i just need 4-5 DVDs to do that.But when i was checked my recovery partition there is about 103GB filled.So i need about 25-30 DVDs!!!!!! Am i correct? or is it a backup?Not recovery?Is there any other way to do recovery??Please help me IT experts????
