discs) will contain all your files. If you need to restore any files, you can do so from any of your
backup discs (or sets of discs).
If you choose to copy only changed files, you can make incremental backups, each new disc (or set
of discs) containing only those files that have changed since the previous backup. In this case,
Intego Backup Manager Pro will ask you to insert the last disc of your previous backup before
copying files to new discs. (For example, if your backup spanned three DVDs, you will need to
insert the third of these discs into your Mac.) This is done so Intego Backup Manager Pro can read
information regarding the files that have already been backed up, so the program will know which
files to copy.
Note: Intego Backup Manager Pro can create multi-session backups on CDs, but not on DVDs; this
is because the Mac OS X framework for writing optical discs cannot write multiple sessions on
DVDs. This allows you to use empty space on CDs for incremental backups. If you back up to CDs,
and have only used half the capacity of a CD, Intego Backup Manager Pro will be able to use the
remaining space for your next backup.
