I'm new to ReaR as well, but I think you need to specify a backup method 
in local.conf.  The default is BACKUP=REQUESTRESTORE.  'man rear' refers 
to this as "Not really a backup method at all..."  It seems its purpose 
is to do just what you've seen:  provide a rescue system and leave the 
backup/restore up to you.

Take a look at the section of the man page titled "BACKUP SOFTWARE 
INTEGRATION".  There is a list of both commercial and open source backup 
software that you can choose to use for your backup and restore.
