Hi,

For those of you who are interested, I have found a way to do it.

1. Create a small partition(example 8GB) that you will use for the Natty
Nvidia Weekly Testing(take note of the partition, example /dev/sda7)
2. Do your installation and update on the new partition and once you are
comfortable, you can start to do the backup.
3. sudo dd if=/dev/sda7 of=ubuntu-os-backup.img (this will do a low level
copy of the partition into ubuntu-os-backup.img file)
4. Do all the testing that you want on the parition.
5. You can restore the partition to the original stage by doing "sudo dd
if=ubuntu-os-backup.img of=/dev/sda7"

*** VERY important notes ***

- As dd is a low-level operation, it will be disastrous if you accidentally
use the wrong value for of=<output destination>.
- It works for me but do it at your own risk.
- The time taken to backup/restore is directly related to the size of your
partition. so remember to choose the appropriate size.
