Protecting business means protect ongoing access to servers and data; traditionally that means backing up the server. However, backing up the server is only part of the equation. If you can’t recover the data, the backup is useless.
The right way to evaluate the quality of your system and data protection is to evaluate the Recovery Time Objective (RTO) and Recovery Point Objective (RPO). These metrics define how long you think it will take you to get back online and how current the data has to be.
