3.3 BackOn Track
BackOn Track lets you easily back up important files to a disc, hard drive, or other
storage device. A Back Up Files project can be scheduled to run daily, weekly, or
monthly. Large backups are automatically spread across as many discs as you
need.

Begin by selecting the drive, drive partition, or folder containing the files you want

certain types of files. You can back up any files that have changed since a specified
date, or create a custom backup based on certain file extensions. Finally, schedule
the project to run on a regular basis, or begin backing up right away.
