Figure 2 Backup process
In most cases, the source is data on a disk, such as files, directories, databases, and
applications. If the backup is expected to be used for disaster recovery, it needs to
be consistent.
Software that actually copies data to the destination is a backup application. The
destination is a backup device, such as a tape drive, with media to which a copy of
the data is written.
What is a restore?
A restore is a process that recreates the original data from a backup copy. This
process consists of the preparation and actual restore of data, and some post-restore
actions that make that data ready for use.
Figure 3 Restore process
The source is a backup copy. A restore application is software that actually writes
data to a destination. The destination is usually a disk to which the original data is
written.
Backing up a network environment
During backups in a network environment, data is transferred over the network from
systems to be backed up to media on systems with backup devices, where the data
is stored.
