What is a backup? Do I need to backup? How do I backup?
Ask yourself the following question – If my computer was stolen, what would I lose?
If the answer is all my photo’s and documents then you should be backing up.
A back-up is when you have copies of your precious files (Photo’s and Documents) stored on another device. Other devices include USB memory sticks, external hard drives, more than one computer and more recently in the cloud.
A back-up is not a back-up unless you have tested it. To test the back up I would suggest using another device and performing a quick scan of the files to see if they open up. So for example your could plug an external hard drive into another laptop and see if you can open the photo’s.
A back-up device should be stored in a physically separate location. This is where the cloud can be useful as it allows you to store your files away from the main computer.
Remember to keep any software you have bought in a safe place – The most obvious one here is Microsoft Office.
Email are normally backed up in the cloud – Try and log-in to your cloud system to check.
How can my files be lost in the first place. You need to back-up your precious files because you can loose them in various ways.
