3. Backups – part 1

From IT Safety column in Doitsu NewsDigest (translated to English)

Have you ever experienced the pain of loosing important data?
Be it important documents you deleted by accident, a USB stick that suddenly refuses to work, or in the worst case a computer that doesn’t boot at all, and you’re faced with a dead screen. There are many ways to do backups and protect yourself from these scenarios and you can learn about some convenient and reliable methods in this article.

First step: What data is most important?

Before deciding what kind of backup you need, you need to first think about the worst case scenario that could happen to your data. Then assess how badly it would affect you if your data was gone or damaged. This will help you see that there are different levels of importance and value of your data.

For example, standard software, movies and music can take up lots of space in your computer, but if lost they can be easily downloaded or purchased again. However, private photos and precious work documents have high personal or monetary value, and they can never be replaced. Once you’ve decided which data is of most valuable to you, you should make a plan to do backups regularly. Once per week is recommended for most users, but for businesses, at least every day, or in some cases every hour.

Quick and easy solutions

For the average person the simplest (and usually sufficient) backup method is to copy the data to a USB stick or external hard drive. However, 20% of hard drives break after 3 years, so always be sure to have copies of your data at least on three different media. It’s also a good idea to store a copy at a different location, just in case of a fire, flood or other disaster.

If you own a Mac, the software “TimeMachine” helps you to do backups automatically.
