Hi,
I am using CentOS 5.Is there any way to take snapshot of a stable state of system which i can restore the system to in case of any trouble(like restore points in windows).

I have no idea if there is something like restore point like in windows but you can surely take the snapshot of your system in case it goes out. You can either use rsync or rsnapshot or CloneZilla for the same.

There's are lots of ways to snapshot volumes from within a Linux install. What is not usually possible is snapshoting the root filesystem of the install you're running on. (though Fedora is apparantly testing this feature using btrfs for release with Fedora 13).

The providers you contacted can offer this snapshot feature to you since the "machine" you get to administer is actually a virtual machine on their servers. You could run a virtual machine within your CentOS install for testing purposes and run snapshots on it, but I doubt you want to be trying to figure this out as a beginner.

So to answer your question: the snapshot feature GoDaddy etc. offered you is a good idea and I'd go for it.

this is what i intended to know.
I faced some minor glitches like video driver apparently was not working.firefox started reacting weird.Though i fixed them but it took a lot of time and patience.
Is there any nearly equal solution(wherein i can keep the image of last stable configuration)?

You need hdd/tape drive/external usb to backup your system with rsync or any other tool.Go for clustering!

This link should answer your question in more details why Linux does not have the restore point feature.
