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.
