There are some other features of the Retrospect package that bear mentioning. However they are not part of the core program's features. But they do make your life a little easier. Retrospect comes on a bootable CD, in case of system crashes. This same cd also includes disk image files so you can make floppy disks for those computers which do not have CD ROM drives.
Manuals are an important part of any software package.
It is increasingly hard to find printed manuals included with a program. Even more rare is a comprehensive manual. Retrospect comes with a very impressive manual. It not only covers the operation of the program itself but explains backup technology, offers many examples and scenarios about back ups, and tips on how best to utilize the program. On a personal note I wanted to point out that this a company which is very responsive to user feedback.
