Hi Vince,

Retrospect (Dantz software) allows for a variety of backup strategies.  It
can do a full "copy" where it essentially creates a duplicate of the files
you're backing up.  It then continues to copy only files that have changed
on subsequent runs.

It also has a "backup" mode which creates one big file (which is the
compressed data itself) with an accompanying "snapshot" which is really
the directory.  the data file and the directory can be kept on seperate
volumes and can recreate one another in case of disaster.  This is the
safest approach, but takes a long time to replicate when trouble strikes.

Retrospect also has something called "Retrospect Remote" which allows for
a central backup server to automate backups of any boxes out there with
the Retrospect Client running.  We haven't used this yet, but plan on
testing it out this summer.
