WHAT IS COMPUTER BACK-UP?

Computer backup is the storing copies of your files on a medium other than your hard disk. The reason that we make computer backups is to protect against the event that something happens to damage our files so they are no longer usable. If we have backups of our files, then we can restore these files to our computer through our backups.

WHAT IS INVOLVED IN COMPUTER BACK-UP

Computer back-ups can be made in very different formats. The traditional method of backing up computer files was the floppy disc. However, floppy discs are becoming increasingly obsolete. It is already not uncommon to not even see a new computer that includes a floppy disc drive when you go to a computer shop. Another format is a USB memory stick. This is becoming the most common format of back-up and is used by many. A USB can hold a lot more data than a floppy disc can and is more easily transportable. That's why it's the more popular option.
