I finally installed the backup utility thanks to the information on
this group but when I used it I noticed that the interesting features
from a real backup utility are missing.
Basically I am referring to that option that allows you to compare the
folders you backup with the one you had backed up before and only add
the new files that have been added or modified since your last
backup, instead of copying again all the contents of the folder.
Is this so or am I missing something?
In the Backup Utility - HELP --> Help Topics --> Index and search for
"Differentials"..
You find this:

Types of backup
The Backup utility supports five methods of backing up data on your
computer or network.
- Copy backup
A copy backup copies all selected files but does not mark each file as
having been backed up (in other words, the archive attribute is not
cleared). Copying is useful if you want to back up files between normal and
incremental backups because copying does not affect these other backup
operations.
- Daily backup
A daily backup copies all selected files that have been modified the day the
daily backup is performed. The backed-up files are not marked as having been
backed up (in other words, the archive attribute is not cleared).
- Differential backup
A differential backup copies files created or changed since the last normal
or incremental backup. It does not mark files as having been backed up (in
other words, the archive attribute is not cleared). If you are performing a
combination of normal and differential backups, restoring files and folders
requires that you have the last normal as well as the last differential
backup.
- Incremental backup
An incremental backup backs up only those files created or changed since the
last normal or incremental backup. It marks files as having been backed up
(in other words, the archive attribute is cleared). If you use a combination
of normal and incremental backups, you will need to have the last normal
backup set as well as all incremental backup sets in order to restore your
data.
- Normal backup
A normal backup copies all selected files and marks each file as having been
backed up (in other words, the archive attribute is cleared). With normal
backups, you need only the most recent copy of the backup file or tape to
restore all of the files. You usually perform a normal backup the first time
you create a backup set.
Backing up your data using a combination of normal backups and incremental
backups requires the least amount of storage space and is the quickest
backup method. However, recovering files can be time-consuming and difficult
because the backup set can be stored on several disks or tapes.
Backing up your data using a combination of normal backups and differential
backups is more time-consuming, especially if your data changes frequently,
but it is easier to restore the data because the backup set is usually
stored on only a few disks or tapes.

I opened the backup utility, and before I even searched in the help for what
I wanted - I clicked on TOOLS --> Options and under the "Backup Type" tab I
found ther selection you were looking for. I thought maybe you have only
used the Wizard.. so I tried it.. And the last thing I got a choice of
doing was clicking on an "Advanced" button and choosing the type of backup..
=)
A little searching and reading what you click on goes a long way. ;-)
