The 3-2-1 backup strategy is widely recognized as one of the most effective methods for creating data backups.
The principles of the 3-2-1 backup rule are straightforward and universally applicable:
Strictly adhering to these simple guidelines as part of a "3-2-1 backup plan" can be a lifesaver for system administrators and experienced PC users in various scenarios.
To provide a deeper understanding of the 3-2-1 backup strategy, let's delve into the terminology associated with this approach.
Creating three or more copies of data on different storage devices mitigates risks inherent to specific devices. For example, hardware failure may affect a hard disk but not a cloud account; network mishaps might interrupt online data transfer but won't impact copying from a local disk, and so forth.
The term "format" refers to physically different representations of data, not just logical layouts. If one copy is stored as hard disk data, ensure at least one other copy is on FTP, tape, or a cloud service. This safeguards data from storage-specific risks.
The final principle of the 3-2-1 backup rule emphasizes keeping one or more backups off-site, i.e., not in the same room/building as the original. This ensures that if the original and local copies are physically destroyed (due to theft, fire, war, earthquake, or any other force), at least one data copy will be preserved.
Note: Nowadays, the optimal choice for offsite storage is often a commercial cloud. Options like Amazon S3, popular services like Dropbox or Google Drive, or even utilizing an FTP server are viable solutions for implementing the 3-2-1 backup strategy.

By adopting this server backup strategy, you can ensure the security of your data. To implement the 3-2-1 rule for backup right away, all you need to do is download Handy Backup.
The implementation of the 3-2-1 backup rule requires the availability of suitable storage devices, accounts, or vaults. However, there are specific requirements for these storage devices:
The significance of the last requirement can be clarified using the example of employing a USB drive for the 3-2-1 backup strategy. Clearly, this drive must be connected to a PC during scheduled backups. If this connection could interfere with other tasks, a viable alternative is to use a local drive instead.
The 3-2-1 rule is versatile and applicable to a wide range of use cases, making it a preferred choice compared to more complex methods like Grandfather-Father-Son or Tower of Hanoi backup strategy. It can be effectively employed for various types of data backup, including:
While the 3-2-1 backup strategy is well-suited for various backup scenarios, it may not be the optimal choice for creating disk images. However, this is not a strict rule, and the 3-2-1 data backup strategy can still be used for system recovery if needed. It's a versatile approach that offers redundancy without strict limitations!

Recent advancements in data protection have expanded the scope of data applications, including tasks like populating data repositories and conducting extensive analyses on large datasets. This extends beyond traditional insurance practices, as companies engage in testing and perform analytical assessments.
However, challenges emerge with evolving regulations such as GDPR, introducing complexity by mandating strict security measures and the ability to delete specific user data from all backup copies. Deleting data can be a daunting task, especially when distributed across different systems and storage locations. It's crucial to acknowledge that compliance with such requirements may face hindrances due to technical limitations or legal obligations. Despite these complexities, the 3-2-1 backup approach remains pertinent. Additional steps, such as recovery testing and granular data searches, have become integral components of modern data protection strategies.
Creating a new backup task is a straightforward process. Begin by following the instructions outlined in the User Manual. In this task, configure it to copy the original dataset from Step 2 to a locally selected storage location on Step 3. Once the first task is completed, make a copy of it in the main window.
Now, open the "Properties..." option from the context menu of the duplicated task. Rename it, and then choose a separate location to store data compared to the first task. You can also adjust the schedule for this second task to optimize data load.
Finally, create a third copy of a task (from the first or second task, it doesn't matter). Rename it again, choose a different location (offsite, such as a cloud) as is typical for implementing the 3-2-1 data backup rule, and re-schedule it. These three identical tasks will automatically implement the 3-2-1 rule of backup.
