Some types of data lend themselves to a compress backup better
than others.  Several of my customers, for instance, do backups
of databases (a few very large files) where the entire backup
must be readable for any part of it to be useful (lots of related
files).  If you have an error in any file, the entire backup is
bad whether compression is used or not.
