![]() The key reasons behind maintaining an immutable or air-gapped backup are essential for protection against ransomware, data integrity, and cyber resiliency. Keeping a copy of your backup immutable and/or air-gapped provides an extra layer of protection and ensures the integrity and availability of critical data. Diversifying the storage media minimizes the chances of losing all copies simultaneously. This diversification provides an additional layer of protection against specific types of failures.įor example, having one copy on a physical external hard drive and another in the cloud protects you from hardware malfunctions and online security breaches. The second aspect of the 3-2-1 backup rule suggests storing the copies in two different formats or media. By maintaining multiple copies, you significantly reduce the risk of permanent data loss. ![]() This redundancy ensures that even if one copy becomes inaccessible or corrupted, you still have two additional copies available for restoration. The first element of the 3-2-1 backup rule emphasizes having three copies of your data. It involves duplicating data three times, storing it on two distinct media types, and having one copy offsite. To offer protection against various data loss scenarios, the 3-2-1 data backup method is designed to be simple. Understanding the 3-2-1 Backup Ruleįor you to adequately capitalize on this backup method, you must first understand what it entails. With the 3-2-1 data backup rule, you can recover data quickly and resume operations, as it keeps downtime at a minimum. You should also consider adopting the 3-2-1 backup rule that helps streamline backup procedures and reduces the risk of data loss by creating redundancy. While protecting your data is a significant first step, it's not enough, as you should also have a robust data recovery plan. However, despite hardware failure and the rise in severity, volume, and cost of cyber attacks, most companies do not have appropriate cybersecurity measures.ĭata suggests that only 25% of small businesses have a data recovery plan. There are as many as 140,000 weekly hard drive failures in the US, making up 45% of all downtime. ![]() This may happen due to a cyberattack or corruption of your storage devices. As an organization, the biggest threat you face today is data loss.
