Backing Up Your Data
Now for a word about redundancy… again! Let’s say tomorrow when you come into your office, you hit the button to turn on your computer and you’re greeted with what is known as the “blue screen of death”. If that happens, you’ll be VERY happy that your external drive is sitting right next to your CPU with all your data backed up on it.
However, if you enter your office tomorrow and find your desk under water… you will be wishing your external hard drive wasn’t floating right next to your computer’s CPU. At that point in time, you will realize that DVDs you made as redundant backups which are floating nearby may or may not be salvageable. At a time like that, you’ll wish your data was safe and sound off site as the result of an automatic online backup.
So when it comes to backing up your data, pick more than one way to preserve your data
This is absolutely correct.
