The 3-2-1 Backup Strategy

Having a solid backup plan is as easy as 3-2-1. The best practice for having your important data be as safe as possible is to follow the 3-2-1 backup rule. The rule is as followed:

3 Copies of your data

You should have 3 copies of your data, the original copy being one of them.

2 Types of media

Your backups should be on two different types of media. For example: CD + Hard Drive or Tape + Cloud (eg. Dropbox) etc.

1 Copy stored offsite

You should have a single copy located somewhere far, far away. You don’t have to move it there yourself. Using a cloud service such as Dropbox, OneDrive, or Google Drive will store your data where it’s safe.

My personal go-to setup is to have my computer backup to an external hard drive and a cloud provider. This way I’ll have a copy that I’m working with, a copy on another hard drive close by for quick recovery, and one in the cloud in case of a major disaster.

When implementing the cloud for backing up of secure files, you may need to take encryption into consideration for extra security. Read more about that here .
