Let’s start by talking about data backup. This is the act of copying data from one location and storing that copied data in another. Data backup can be done on a USB drive, external hard drive, an offsite server, or any other storage device.
The purpose of this practice is to protect your data in the event of something like hardware failure, a natural disaster, or a cyberattack. Since the information isn’t stored locally, if your device experiences a data loss event, you still have access to whatever you saved. Think of data backup as a security blanket for your company.
