What Is Backup and Recovery?
Backup and recovery are the process of creating copies of your data and storing these to protect you and your organization against the results of the loss of this data. You may find this referred to as operational recovery in some literature.
During these processes, data is restored to its original location in most instances. Sometimes it is necessary for data to be restored to an alternate location where it can be used. It is common for this backup to be stored in a separate medium or system to ensure the best protection against data loss when a primary hardware or software failure occurs.
