Be careful backing up that often. If you overwrite a file by accident
the
backup will be overwritten before you even notice.


Nonesense, you are not doing it correctly .Any respectable Imaging S/W
lets you keep as many Image copies as you want .Normally the Image
filename contains the date/time plus any name you give it .Each image
will not be overwritten unless you have mis-configured the program .

It is also worth remembering that Image S/W can fail, so always best
to have at least two different Imaging Programs and create Images
inline with your workload schedule / Data collection .
I've never had to revert back to the original Installion CD/DVD etc in
the past 10 years .
