If your computer got stolen, how much data would you lose? Wedding photos, baby photos, important documents, photos of your recently deceased grandparents?
It’s vitally important that you have a backup solution ready for when disaster strikes, and one backup isn’t enough.
The basic principle of 3-2-1 Backup, is you have 3 copies of your data, stored on 2 different types of media and 1 of them is off site.
A good example of this is having one backup on an external hard drive at your house (local backup) and an online backup (offsite backup).
