Backing up data your business data is crucial. As power outages and accidental losses are frequent, you should ensure a backup for all your business files so you don’t have to suffer from the loss of important files.
The 3-2-1 backup strategy is really helpful when dealing with such problems. It helps you figure out how to backup your data for enhanced security. Here is what you need to know about it.
This strategy is tested and used by numerous businesses and is helpful under all circumstances. The 3, 2, and 1 indicate the number of copies you have to make of a file. According to this rule, you have to,
- Make 3 copies of your data.
- Keep 2 copies on different storage media devices
- Keep 1 copy offsite
This multiple-layered backup ensures you can access your data in case of any unforeseen loss. Let’s dive deep into the three requirements of this strategy.
It is the minimum number of copies you must have for a successful backup strategy. 3 copies mean you have multiple layers, so other files are available if one file fails or corrupts.
However, if you are storing all three copies on the same device, you could get in trouble, and the backup strategy could fail. This is where the second point of the 3-2-1 rule helps you.
To avoid losing backup files due to the failure of the storage device, store your copy files on different devices. This way, even if one device fails, you have the other at your disposal.
Though you can store backup copies on as many devices as you want, according to the 3-2-1 rule, you must have 2 copies on different devices.
Now that you have stored the two copies, the rule proceeds to explain what you should do with the remaining copy. Store this copy in a remote location. You can store it on a hard disk in your faraway farmhouse or cloud.
Though offsite backup files aren’t readily accessible, they offer an additional layer of security for sudden data loss.
