How do you create a clone/image? I back up to an external hard drive (not often enough, doing now, thanks Kev), but I don't understand the whole ghost image thing or whatever it is.
A "clone/image" file is a snapshot of your whole hard disk in the exact state it is in at that time - including all of your precious files, the operating system, all of your installed programmes and plugins
So - if you take a clone image of your hard drive and put this image file on to your external hard drive you will always be able to get back to the exact state your computer was at when you did the clone image - often within a few minutes!!!!!
This is perfect if you want to change your internal "C drive" to a bigger one - you simply create a clone, put the new hard drive in, copy the clone to the new hard drive and voila - you are up and running
It is obviously also the dream backup solution - if your hard drive fails (eg gets corrupted, physical failure, virus infection etc.) you simply need to get a new one and reinstall your image and you are up and running - no faffing around re-installing operating systems, updates, programmes etc.
I would also highly recommend the
FREE Macrium Reflect (which I have used successfully myself)
The only caveat is that the clone image files may not install on a different PC (so if a laptop got stolen it is not a complete safety net - so keep your installation discs or files for downloads) as some programmes link themselves to the computer ID and the drivers will be expecting the exact same setup as your old PC)
However, changing PCs is always a good time to have a fresh start and just install the prgrommes you need
I would therefore suggest a sensible backup solution would be:
Create an image of your C Drive
Create another backup (on the same hard drive if it is big enough) of your folders, files and any software installation files you have downloaded
When you have created this backup on one external hard drive - copy the entire contents on this hard drive to another external hard drive (it is said data is never deemed safe until it is in 3 different places)
Ideally, you would then want to keep one of these external hard drives "off site" (at work, a friend's house, a relative etc.)
I would also suggest a separate backup of really important files (especially family photos, music files etc.) to DVDs and put them somewhere safe off site
