If you tell someone that your computer crashed, the first question you usually hear in response is “Did you back up your files?” That’s the right question to ask if you’re talking only about personal data or a single computer. When your PC crashes, having a data backup available is usually all you need to restore your normal routine. But if it comes to a company, backing up data is not enough. When a company’s infrastructure is damaged or data is lost, a full disaster recovery operation needs to take place to restore operations without causing critical disruptions to the company. Disaster recovery requires much more than simply backing up files.
