The 3-2-1 Backup Plan
Data is important in both business and personal settings. It needs to be backed up or it could be lost, causing extensive damage. Below is a helpful rule to follow to ensure your files are safe and secure.
The accepted rule for backing up data is the Three-Two-One Rule. It can be best summarized as having:
- At least THREE copies
- In TWO different formats
- With ONE of those copies off-site.
Having three different copies means storing them in three different locations. Storing all three copies in the same location raises the risk of losing your data to an unplanned event. By keeping them in different sites, it reduces the risk of a single event destroying multiple copies.
What are different formats? Different formats means using at least two different methods to store your data. For example, burning your photos to a DVD from your PC’s hard drive qualifies as two different formats. Using different formats reduces the risks that all your backups will be damaged, as different formats have different strengths and weaknesses when it comes to redundancy.
Keeping one copy off-site ensures that even if something happens to your primary storage location, such as a fire, or a break-in, at least one copy is safe in another locale. By complying with this rule, you can rest assured that if something does go wrong at one of your physical locations, at least your data will remain safe.
