Windows 7: size of backup disk

size of backup disk

For extra backup security I was going to buy another 320 GB external drive for storing system images. Another thread stated that for system images the backup drive must be a higher capacity than the drive being backed up. That is you couldn't backup a 1 TB drive with say 100 GB used to the 320GB external drive?? Is this correct?

Most backup programs will compress the images it creates. It won't be more than the used space of the HDD you want to backup. However if you have a 1TB HDD with only 100GB used, you can easily create multiple smaller partitions and back them up individually.

Putting the question another way:
I have a 1TB hard drive with 2 500GB partitions (C,D). I want to store a windows system image of c: on a 320GB external hard drive. The system image takes up about 40GB. Can I do it (yes or no).

Or does windows want to see a physical external drive at least equal to the size of the 500GB c: partition. (as stated in another thread).
