3-2-1 Backup Rule

| Comments

With holidays upon us, families around the country will be generating millions of images and gigabytes of video files. Unfortunately these will remain on people’s cell phones until a catastrophe happens. Either they lose the phone or a device failure will render their memories lost. The only way to protect yourself is to have a clear back strategy.

Here is where the 3-2-1 backup rule comes into play.

Backups are good, but they may be useless without redundancy. This being said, a good backup strategy is a sure way to protect your data from any malfunction, erroneous activity, or disaster coming your way. Here, the 3-2-1 rule comes into play.

Key parts of this strategy:

  • Three copies of all data locally.
  • 2 backups - each on a different physical media.
  • And finally, a copy goes to the cloud.

This may seem overkill but the cost data loss is too high, which is why it is very smart to be ready even for any eventuality. The 3-2-1 backup rule is your way to keep data safe.
