What is “The 3-2-1 Backup Rule” that prevents the loss of important data due to unforeseen circumstances?

In recent years, the volume and importance of data handled in business and personal life has been increasing at an accelerating pace.

The loss of data due to natural or man-made disasters can have a fatal impact on a variety of things.

Hello, This is Santoshi.

I too have experienced the crash and corruption of data stored on a single hard drive and photo data stored on a single SD card many times.

Once memories are corrupted, it becomes difficult to restore them.

So here are some countermeasures.

Technology expert Kevin Soltow explains that people can keep their data safe in the event of an unforeseen event by backing it up according to “The 3-2-1 Backup Rule” proposed by Veeam, a data backup service provider.

The reason for backing up data is so that if some problem occurs, the data can be restored from the backup.

Today’s hardware and software are undoubtedly fragile. But for some reason, many people assume that they will not break for a while.

Data is becoming more and more important to businesses and individuals.

Kevin Soltow points out that we need to always live with the risk that “something unforeseen may happen and data may be lost.

Also, there are many possible causes of “data loss” in a nutshell.

It could be a disaster affecting hardware, physical destruction of the device by a malicious person, loss of data due to malware infection or simply a mistake. Backups must be able to handle all of these scenarios.

Backup redundancy” is important in dealing with various data loss scenarios.

If data is backed up in only one way, the backup data may be lost for the same reason as the device on which the original data resides.

The “3-2-1 backup rule” proposed by Veeam is a backup method that focuses on backup redundancy.

●3 copies of data

The “3-2-1 backup rule” is a redundancy method.

First, three copies of the original data are created; Veeam first creates the “first copy” from the original data.

Veeam then recommends making the other two copies based on this copy.

●2 different media

If all three copies created are stored on the same storage media, all copies could be lost if that hard disk media becomes corrupted.

The “3-2-1 Backup Rule” is a mechanism to divide the media on which copies are stored into two or more, such as “Server and USB drive,” “Server and SD card,” or “Server and NAS.

The above makes it possible to restore from the copy remaining on the other media in the event of a problem with any of the media.


●1 copy offsite

It is recommended that one of the three copies be stored physically away from the office or home.

Store the SD card containing the data in another office.

Store copies on a server far from the office.

Use a cloud storage service to store the data in an external data center.

In any case, it is necessary to maintain a physical distance between the data.

This ensures that even if one point is devastated by a disaster or other event, the data can be recovered from a copy stored in a remote location.



Finally, Kevin Soltow said,
the cost data loss is too high, which is why it is very smart to be ready even for an alien invasion. The 3-2-1 backup rule is your way to keep data safe even during this one!
