Loosing our files is pretty frustrating. Imagine saving all your work in your computer and for some reason it crashed and can’t access your file. This is something that will definitely make you feel mad. Let’s see, you can avoid this kind of headache and there are different ways to do that. It is better if we have a flash drive (USB memory keys) it’s pretty cool and they are so small so you can carry it anywhere if you want to. Then we have discs, you can burn your files in your discs so that you won’t have to worry accessing your files incase something happens in your system. Or you can get an external hard drive. Having an external hard drive attached on your system is a good way to prevent data loss. So incase everything was lost, all you have to do is to replace very thing to a replacement drive. Backing up your files is a good way to defend yourself against data loss.
