In the IT world, the 3-2-1 Backup Rule is a common backup and recovery strategy for any lost data. Its simple name makes it easy to remember that you need 3 copies of data, on two different media and 1 copy offsite. The rule basically answers, 1) How many backups should we have, and 2) where should we store them. In this blog, we will discuss the 3-2-1 backup rule in more detail and why it’s important.
Now, the world’s most valuable resource is data. So, there is no reason you shouldn’t be protecting the most valuable component of your business.
The 3-2-1- backup rule indicates that you should have 3 copies of data. That means your original data as well as at least two backups. And that’s the bare minimum.
Each copy reduces the chances of losing any data no matter whatcircumstances come your way. Here is a list of ways your data can be lost orcompromised:
Don’t believe it could happen to your business?
Back in 1998, when Pixar wasn’t part of Disney, they were working on a film called Toy Story 2. One day they realized that their work was vanishing from their servers. At the time, Pixar was using tapes to back up their work. This strategy helped them restore from previous work they lost. However, they weren’t consistently using the tapes and didn’t realize they weren’t backing up properly. This is a very common oversite/error in the industry, where companies neglect “testing their backups” on a regular basis. Yes, it’s shocking. They didn’t have a backup of the movie.
Regardless of your industry, size, or product, have acomprehensive backup strategy and be sure the 3-2-1 rule is observed!
(An employee had a personal copy of the movie and they were ableto retrieve it. In other words, it was their third backup that saved them.)
Now, we know how many backups we need. The second part of the 3-2-1 backup plan is storing your data on two storage devices. To be more specific, storing your second and third backup on different media.
Let’s say you take hundreds of pictures on your trip to Italy. Youstore the pictures on your phone. You may print them, or store them on anexternal drive. If your phone stops working, you still have a backup of thephotos on your drive. The same goes for your data. You need at least twostorage types; in case one fails.
Here is a list of storage media to choose from:
The final rule of thumb is to keep one of your backups, which is on a unique media, in a completely separate location. This way, you have 1) your primary data, 2) your second backup on a different media and 3) your third backup, on another media, and offsite.
You want to create space between your primary data and yourbackup. If there was a natural disaster, your primary data would becompromised. And your backups would be compromised if located in the same room.As a result, this offsite copy is important for disaster recovery so you cansafely restore your data after a crisis.
