Figure 12. Backing up data from a ReadyNAS system to a secondary device (USB drive)

If you store primary copies of your data on your computer or other device, you can create a backup job to back up
your data to a ReadyNAS system that is on the same network.

Figure 13. Backing up data from a computer to a ReadyNAS system

A full backup makes a copy of all the data stored on the primary system. Your first backup of a primary system is
always a full backup job. The amount of time a full backup takes depends on the amount of stored data.

An incremental backup copies only the data that changed since your last backup process. An incremental backup
job takes much less time than a full backup job.

RAID configuration of disks is not a substitute for backing up data. RAID configuration protects
you from data loss only if a disk fails. For more information about the protection that RAID
configuration offers, see 

 on page 22.

A backup source or destination can be local (stored on the ReadyNAS) or remote (stored somewhere else). If the
backup source or destination is remote, you must select the backup protocol that you want to use (see 

 on page 218).

Local options for backup sources and destinations are described in the following table.
