If you want to just backup some files and folders, I nurn them to DVD's. I also use an external hard drive. Some people use an evternal storage device.
Most programs come with disks and some can be redownloaded. The ones that are no longer there, back those up also.
Remember always make backup copies of items that you can't afford to lose.
I am looking for a free data backup software and I google "backup software" there is EASEUS data disk copy.
Somebone told me that you could backup your data without creating a new partiton on the destination harddisk, if possible? Thanks for any replies.
