Backup programs

Today I looked at software to copy my files. It's called "backup" software.

I didn't realise how important it is to backup my files. I don't copy the files on my home computer but I will now.

My teacher explained different ways to copy your files. We used a program called "Microsoft Backup" which copies files and makes them smaller. I can later copy them back to my computer if I accidentally delete them or have a problem with my computer which means that I don't lose my stuff.
