Reliable backups are the backbone of your IT “Disaster Recovery Plan” and “Business Continuity Plan”. Catastrophe can hit any business, no-matter how small or big you are, and catastrophe can come in many forms such as: fire, hardware failure or “ransomware”. The more data lost, the greater the impact on your business. Part of getting your business back up and running after a disaster, is being able to restore operations to where they were before the problem occurred. Businesses who have learned the value of backups employ the 3-2-1-0 backup rule. Lets take a quick look at each one of these rules.
Rule 3: Maintain at least three copies of your data and applications. That’s the one copy you’re using and two backups. This way, if one of your backups is unavailable for any reason, you can still recover what you need in a reasonable amount of time.
Rule 2: Store your backups on at least two different types of media. One reason for this is each type of media has its own vulnerabilities, and you don’t want both of your backups susceptible to the same problem. By utilizing different media, you can reduce your exposure to the same incident preventing access to both of your backups.
Rule 1: Keep one of the backups in a different location. Consider a catastrophe at your business, such as a break-in, fire or natural disaster. If all of your backups are at the same location, they will all be affected. This can result in total data loss for your business.
Rule 0: Verify your recovery plan has zero errors. It is not uncommon for businesses to implement a backup plan but fail to verify it is performing as expected. Regular testing is critical to ensuring you can recover your business data and applications in the event of a disaster.
It doesn’t matter if you are a business or home computer user, if you have anything on your computer that matters to you, it is your responsibility to make sure you have a backup plan in place. In my 20+ years of experience in the IT industry I have seen brand new hard drives fail within 90 days of purchase. I have seen years of family pictures vanish by accidental deletion and I have seen “un-tested” backups fail to restore important business files – files which everybody “thought” were being backed up.
