![]() But most people who believe they can’t store backups in the cloud are frequently misinterpreting what’s required of them or the limitations on where they can store their data. Perhaps they’re conflating that with a regulation against storing data outside of their home country such regulations are common. But this is often misunderstood to mean that they can’t store any of their data in the cloud. The most worrisome situation I see is when I urge a company to store a copy off site – the 1-rule – and the admins say, “We’re not allowed to do that.” Their business operates with regulations and standards that the data must be protected and cannot be stored offsite. However, even the smallest organizations are not too small to be the target of a ransomware attack or a natural disaster. Maybe they’re too small to have a second data center of their own, or they don’t have the staff to select, set up and maintain that second location. They’ve broken the 3-2-1 rule already by ignoring the importance of storing data at two locations with another being off-site. Breaking the 2: No second locationĪ common scenario is that organizations will back up their data – that’s wise – then store the backup on a server in their data center – that’s unwise. They’re backing up to disks that they own – maybe even disks that have been repurposed from something else – instead of spending budget to have a secondary location. Why do I need a third?” But when I dig a little deeper, I usually discover that it’s a matter of cost. On occasion, some admins balk at the idea of going to the cloud or investing in a tape library for that third copy. Breaking the 3: Not enough copiesĪ common mistake is to ignore the importance of having 3 copies of protected data. But despite the best intentions some companies encounter challenges even implementing the 3-2-1 rule. The 3-2-1 backup rule is the bare minimum of an effective data backup strategy and a good starting point. What challenges do organizations have in setting up a 3-2-1 backup? What mistakes do they make? Why? Because additional enhancements to the 3-2-1 rule can give you better protection against ransomware, help lower your storage and bandwidth costs and make your business more cyber-resilient should an outage or disaster strike. But most companies would be well advised to look at the 3-2-1 rule as the bare minimum. Those are solid, minimal goals for a data protection strategy. I’ve seen Quest customers adopt many variants to the rule, which is typically defined as: System administrators have long observed the 3-2-1 backup rule for data protection. In an era of evolving threats, it’s worthwhile to re-examine ways to enhance the 3-2-1 rule to more securely protect backups. While the 3-2-1 backup rule offers trusted guidelines for the number and distribution of backup copies a company keeps, it doesn’t extend to other techniques that enhance the security and safety of organizational backups. The 3-2-1 rule and backup strategy is a prime example. Though some ways of defending against these threats have changed, backup strategies have remained the same. As the IT threat landscape changes, organizations must adapt to defend against ransomware and cybercrime.
