I read the other day about someone who backs up their computer the way I do. So I thought I would share the method with you.
There are problems with how many people back up their computer. Usually they only back up their documents (pictures and music, for example) and many folks do not even know how to back up their emails. If their computer crashes, they will have to reinstall the operating system and all their programs and may never get back their emails and contact information.
Here's what I do in addition to making a backup of my documents and data files. I make a clone of my hard drive.
I attach an external dock for a sata hard drive. I put a sata drive in the dock and then I run software that clones everything on my working hard drive unto the drive in the external dock. If you but a Western Digital hard drive you can download software (Acronis True Image) from the Western Digital site that will allow you to make a clone. There are also other utilities you can obtain that will also perform this task.
If my hard drive dies, I just uninstall it and install the clone and I am back in business. I will lose whatever I have created since the last time I cloned the disk, but it may be retrievable from the regular data backups I also do.
If you have an eSata port on your computer you can test the clone by setting your computer to boot from the eSata port.
This method probably works best for desktops.
