![]() ![]() The server has two active copies and one passive copy in case of failure. How does this work in practice? One example of the use of three replicas is Windows Fabric, a technology known from The 3-2-1 backup rule states that three backups must be kept, two of which should be on two different media (usually disk and tape), while one copy must be outside the primary data center. For example, the White House Administration recommends in the US-CERT (Computer Emergency Readiness Team) document the implementation of this very formula. The 3-2-1 backup rule has been in use for many years and is supported by solution providers, businesses, and governments. However, to obtain a solution, it is necessary to assess: the advantages and risks of each medium, financial resources, and needs, such as the amount of data to be archived, the protection of sensitive data (customer data, identifiable information), and data availability (permanent archiving, temporary backups). Are they worth considering, or is it better to stay with a familiar formula? There is no clear answer to this question. However, in recent years alternative concepts to 3-2-1 have been emerging. IT departments have learned an important lesson from this unpleasant experience: data should not remain solely on the user’s computer, and server resources must be adequately backed up to remote locations. Its popularity has further increased after ransomware attacks such as Petya. Many IT managers choose a method that has been used for years, referred to as 3-2-1. The generals need to develop an action strategy and put everything together carefully. Even investing in the best tanks and combat aircraft does not guarantee victory. But buying new software or hardware is only the first step and is akin to an army purchasing the most modern weapons. To put it simply, this means that the risk of data loss will increase to unprecedented levels.Įxperts are calling for the replacement of Backup and DR solutions. Security experts are under no illusions – Russian hackers are expected to retaliate against the West in the coming months, resulting in unprecedented cyber-attacks. In the coming months, data protection will present even more difficulties than before because of the war in Ukraine. Interestingly, in as many as 84 percent of attacks, the attackers made their victims’ data public. In the latter case, ransomware has the most severe effect on businesses.Īccording to Coveware, in Q4 2021, the average decryption fee was $322,168, a 130 percent increase from the previous quarter. What explains the sudden increase in the awareness of Backup? The two main reasons are the increase in the value and importance of data and the increase in cyber-attacks. However, this formula has become outdated in recent times, and only the most inconsiderate users fail to make backups. Until recently, people were divided into those who do Backup and those who will do it. What are they changing, and how can they realistically affect company data security? We invite you to read on. Importantly, companies are gaining new opportunities in this area – alongside the standard 3-2-1 rule, new concepts are emerging. The backup strategy is almost as important as the data protection solutions used.
