Hi all,

the following are the driver backup utilities which I have found on the net

i) Double Driver
ii) Chilly device driver backup
iii) Jermar softwares WinDrivers backup
iv) Fabs Auto backup

unfortunately all these are meant for windows O.S , now my question is there a similar utility for linux?

Linux and windows work very differently. Just because you are used to doing a certain task on windows does not mean that it is valid to do it under linux. Linux users don't live in a world of graphics card driver CD's and the likes. A "driver" is generally either in the kernel that came with your system or it's not. It's very unusual, and increasingly so as time moves on, to need to add additional kernel modules like this. Software is generally not seen to be "a driver" as such, at a prepackaged level, it's just another rpm or deb file that gets installed, they aren't managed separately.
