How Intego Backup Manager Pro Protects Your Files
Intego Backup Manager Pro works by preparing a list of files to be copied, based on your
selections, then copying them intelligently to the destination you have chosen. There is a wide range
of rules and copying options; we’ll go over them in chapter 4 ( Script Options ). But rules and
options generally fall into three categories: backups, synchronizations, and bootable backups. A
fourth category, restorations, is when you return files that had previously been copied to their
original locations.
A backup copies specific files and folders, or the contents of entire volumes or hard drives, from
one location to another. The location that contains files at the beginning of the process is called the
source ; the one receiving the copied files is the destination . To keep the backup files safe, the
destination files should be stored and never modified, and should be on a different storage device
from the source. For example, you might back up files from your MacBook onto an external hard
disk that you keep at home: then, if the MacBook gets stolen, you still have copies of your files on
the external disk.
A full backup contains everything on your hard drive—not just your documents, but also all
applications and system files. While a full backup takes a lot of space, it can also save you from
having to reinstall applications after a crash, and offer an insurance policy when installing unknown
software or a new version of Mac OS X.
One common backup strategy is to make a complete copy of all your files when you first run Intego
Backup Manager Pro. Then on each subsequent run, you direct the program to copy only those files
that have changed since the last backup. This is called an “incremental” backup. (Don’t worry—
Intego Backup Manager Pro makes these easy.)
Restoring is the opposite of backing up, and is usually performed when the source files have
disappeared or become damaged. You copy files from the destination disk back to the original
source. (In our example above, these files would go from the external disk to your MacBook.) Of
course, these files will only be current as of the last time you performed a backup: if you’ve
