Administrator Mac OS X is a multi-user operating system, and at least one user is an
administrator who can decide when certain system-level tasks or changes are
made. You must enter the administrator's password to authorize such changes,
which include installing new software or copying certain files under Intego
Backup Manager Pro.
Backup A backup is a copy of files and folders made from one location, usually your
active Mac, to another for safekeeping. Backups can be made to other
computers, to other disks or partitions, or to removable media, such as CD-
ROMs, DVDs or memory sticks.
Bootable backup A bootable backup (or "clone") is an exact copy of a startup disk, including all
invisible files and components necessary to start up your Mac. If you have
system problems, you can copy the clone back to your startup disk and avoid
having to reinstall Mac OS X.
Destination The device or location to which files will be copied. In a typical backup, that
would be the backup disk or other medium (such as a DVD). Synchronizations
have no "source" or "backup" because both sides are equal: by default, a file
could be copied in either direction, depending on which volume contains the
most-recent version.
Device Generally speaking, any computer hardware. As is used in this user's manual, a
device is a piece of computer equipment that can store files. Your Mac's hard
drive, an iPod, a memory stick, and a DVD drive with a DVD in it are all
devices.
Disk image A disk image is a volume that is created as a file. You can copy disk images
from one volume to another, and, when you double-click them, they open as if
they were separate disks.
Image file See "Disk image".
Incremental A strategy whereby you perform a complete backup once, and then on each
backup subsequent backup copy only files that have changed.
