Backup media can include reel-to-reel magnetic tapes, DDS tapes, 3480
cartridges, magneto-optical disks, and disk files. Backup media
provides an economical way to maintain duplicates of important files on
your system.
The process of copying a file to backup media is called storing the
file. The process of copying a file from backup media is called
restoring the file.
As a system administrator/operator, you frequently STORE and
RESTORE files. You might, for example:
Store all files on the system (backup) in case one or more files become
corrupted, either accidentally, intentionally, or by a malfunction.
Store an important file in order to create a duplicate for a user.
Permanently store several files offline by storing them to media and
deleting them from disk (archive).
Transfer files from one system to another by storing them from one
system and restoring them on to the other.
