In modern technology, the value of data cannot be overstated. The 3-2-1 Backup Strategy has emerged as a highly recommended approach to safeguarding critical data. This article will explain the principles of this strategy and suggest a secure and effective backup tool, EaseUS Todo Backup.

Twenty years ago, individuals heavily depended on hard drives with maximum capacities of 30 GB and CDs to safeguard their data. To mitigate the risk of unintentional data loss resulting from these limited storage options, Peter Krogh introduced the 3-2-1 Backup Strategy. This write-up aims to explore the intricacies of the 3-2-1 Backup Strategy and demonstrate its implementation using a dependable and secure backup solution, EaseUS Todo Backup.

What is the 3-2-1 Backup Strategy

The 3-2-1 backup rule is a groundbreaking data backup strategy that adheres to the following stipulations:

• Generate three copies of your data. This means maintaining the original data on your primary device and creating at least two additional copies.
• Store the data on two different types of media. Utilizing different media can decrease the risk of data loss due to media failure or damage. The choice of storage media is flexible and can be tailored to your preferences, such as a computer or an external disk.
• Maintain one backup copy off-siteHaving an off-site copy safeguards against data loss from local disasters or site failures.

作为最安全的数据保护方法之一,the 3-2-1 backup strategy mitigates many risks associated with backup procedures, guaranteeing that there is no single point of failure for data. In the event of data loss due to unforeseen circumstances, here's how the recovery process works with the 3-2-1 strategy:

• All data is unavailable. Inevitably, sometimes you will make some changes to your devices when using your computer. In the case that you need to recover your data, backing your devices to the original status, you can directly restore any of your backup copies.
• 原始数据不可用。如果原始数据is corrupted, damaged, or lost, the first alternative is to recover your data from the other two backup copies which are stored in-house.
• The second data copy is unusable. If your storage media are unusable, the off-site copy should be recovered to your in-house servers.
