Since it is impossible to protect your data 100% from every conceivable risk, your best weapon is a bulletproof backup process. The 3-2-1 backup strategy was designed to do just that. Let’s take a closer look at this strategy, which consists of protecting your data by having 3 copies of your data on 2 different media, 1 of which will be physically backed up outside your main site.

3 copies of the same file
In addition to the raw data on your main server, you need to take care of 2 additional copies that will be made regularly. Losing a few hours of data is obviously better than a week!

2 different types of media
In order to ensure that a failure doesn’t occur on two similar types of media at the same time, it is preferable to use 2 separate media solutions.

1 external copy
In the event of a disaster, it is important that a copy of your data be off your main site. The Cloud backup option is the best choice for this.

+1: The archive
And for those who like bonus points, we suggest that you take an additional backup on a USB key or external hard drive at regular intervals, made by a technician on a different medium each time. This copy, frozen in time and completely independent of the online data, will allow you to protect yourself even more from a possible contamination by ransomware.

So here is an example that would follow the 3-2-1 backup strategy:

• Raw data on your file or production server;
• A backup on NAS;
• An external backup on a Cloud;
• +1: Backup on an external medium every 3 months.
