What is disaster recovery and backup?
There’s an important distinction between backup and disaster recovery. Backup is the process of making an extra copy (or multiple copies) of data. Disaster recovery, on the other hand, refers to the plan and processes for quickly reestablishing access to applications, data, and IT resources after an outage.
