![]() Protection of ransomware and cyberattacks, as you have off-site backups that aren’t easily accessible to attackers. Resilience to accidental deletions and user errors, as having multiple copies of your data stored in different locations ensures that you can easily recover it once it is deleted or altered. So, if one of your copies becomes corrupted, you can use another unaffected copy to recover your data. Security against data corruption, as all your copies are stored independently. Protection against hardware failures, as if your primary storage instance fails, you always have copies on different storage devices, including a remote location, to recover data from. Thus, among the advantages of the 3-2-1 backup strategy, we should mention:ĭata redundancy and availability, as even if one of your backup copies becomes inaccessible or corrupted, you always have other copies to rely on. And, as a result, at least one backup copy would remain accessible for restoring your critical data. ![]() Thus, by distributing backups across different locations, the risk of simultaneous disasters impacting all copies is significantly reduced. It emphasizes creating three copies of data, storing them on two different media, and keeping one of them off-site. Traditionally, in the context of data backup, the 3-2-1 backup rule has long been regarded as a go-to choice and a widely accepted practice. ![]() And the 3-2-1 backup rule is one of those measures that can help you with it. To be able to withstand any disaster scenario and prevent data loss, you need to create a robust and resilient backup and data protection plan. Moreover, we shouldn’t forget about compliance with security requirements and international security audits, like ISO 27001 and SOC2 Type II which mandate stringent data protection measures, making backups crucial for meeting regulatory standards and ensuring data integrity during audits. All these pitfalls underscore the necessity of backups. So, what can go wrong with your vital data? Among the main threats, we can mention human errors, accidental or intentional deletion, hardware or software failures, and natural disasters. And, backup is the best practice against data loss. There are a lot of situations when you can lose your mission critical data. But, first, let’s figure out why actually we need a backup… Why do you need backups? You may have heard a lot about the 3-2-1 backup rule, the “golden backup strategy”, but is it still so up-to-date? Or there are other modern “rules” that can prepare you better for any disaster scenario? Let’s figure it out and dive deeper into what the 3-2-1 backup strategy is, its pros and possible cons, and see if there are any other alternatives to substitute it. That’s why having a backup strategy is essential. Losing access to critical data can have severe consequences, impacting productivity, decision-making, and even business continuity. Whether it’s manufacturing, retail, or service-oriented businesses, the importance of data cannot be overstated. In today’s digital age, organizations across various industries heavily rely on data for their operations.
