Why Backup your System Drive with a Cloning Program?
The short answer » time. If disaster strikes either your drive (mechanical failure) or your system (PC won't boot), a backup image allows you to get "back up" & running in short order (minutes to an hour .. depending on how much data is stored on your system partition, and whether you need to replace your boot drive, which can take 15 or 30 minutes).
If your hard drive dies (mechanical failure), and you have no back-up image handy, you'll have to install your operating system from scratch.
This involves finding current drivers for your hardware, service packs & updates for your operating system (.. all of which takes a TIME).
Then you'll have to install & configure all your programs. This may involve digging up lengthy serial numbers or placing calls to companies that sold your the software. This process is not only time-consuming & tedious, but mind-numbingly boring. In other words » it suks.
It takes me the better part of a week to get back up and running if I have to install my operating system from scratch .. if I hustle.
This is why having a backup image on hand brings » peace-of-mind .. a side-benefit (to saving time) and another reason to embrace Cloning technology. Being prepared for disasters may even help you sleep better.
SYSTEM RESTORE » Windows comes with it's own disaster recovery utility .. called System Restore. SR may (or may not) be able to help in the event of a PC that won't boot.
But it definitely WON'T help if your drive dies (mechanical failure) .. because the restoration files are stored on the same drive as the operating system.
I disable System Restore after creating a backup image, since a backup image offers better protection and renders the SR files redundant. Plus, you can save lots of space by disabling SR, which reserves 10% of you drive by default.
SYSTEM MIGRATION » In addition to the benefits already mentioned (which fall under the heading 'Disaster Recovery'), cloning programs also make it easy for you to migrate your operating system from one hard drive (usually older, smaller, slower) to another (usually a newer, bigger, faster).
