modified those files since then, that subsequent work will be lost—hence the need to make regular
backups.
Synchronization twins a source's contents so both the source and destination are identical. The
first time you run a synchronization, Intego Backup Manager Pro may copy many files to ensure
that both the source and destination contain the same elements. But after that, only those files that
are changed on one side are copied to the other side, and, by default, items removed from one side
are deleted from the other. Since you may update some files on, say, your Desktop Mac and others
on your laptop, a synchronization can keep both of these Macs up to date with the latest versions of
each file. Changing file A on your desktop Mac and file B on your laptop means that, when
synchronizing the two Macs, file A will be copied to the laptop and file B to the desktop Mac. The
result is that the source and destination are always maintained as exact duplicates of each other.
A bootable backup copies a volume with Mac OS X on it to a second hard disk so the new
location can act as a startup disk. The bootable backup process creates an exact replica of the
source, so that destination can function exactly as the source. If you have a system problem on your
Mac, you can connect the backup disk, restart your Mac while holding down the Option key, select
the backup disk and start up your Mac. You can copy all the user files on your Mac to a safe
location, then "restore" the bootable backup to your Mac by performing a bootable backup in the
opposite direction. You'll then be up and running without having to reinstall Mac OS X, its system
updates, and your own applications.
