ReadyNAS for Home RAIDiator 5.3 Basic Backup Concepts A backup is a copy of data that you use if your primary copy is deleted or damaged. The process of storing primary data on a second device is called backing up. The process of restoring backed-up data to the device where the primary copy is kept is called recovery. A full backup makes a copy of all of the data stored on the primary system. Your first backup of a primary system is always a full backup job. The length of time a full backup takes depends on the amount of stored data. An incremental backup copies only the data that has changed since your last backup process. An incremental backup job takes much less time than a full backup job. Note: RAID configuration of disks is not a substitute for backing up data. RAID configuration protects you only from data loss in the event that a disk fails. For more information about the protection that RAID configuration offers, see RAID on page 18. A backup source is the place that data that is being backed up is primarily stored. A backup destination is the place where the backed-up data is stored. If you need to recover your data, the backup target becomes the recovery job source. Your ReadyNAS system can manage backup and recovery processes for many devices on your network. For example, you can back up data that is stored on your ReadyNAS storage system to other devices, for example, a USB drive. Backup and Recovery 77
