Rd actually has this capability built right in (and it does as of about
2 hours back work when the DB is called something other then

Assuming rduser has Lock Tables privilege (Fred, how would you feel
about granting this to rduser for the rivendell db when we create the
initial database?), and that the db server has sufficient available file
handles then each host on the network can be setup to take its own
backup of the db onto its local disk every day and to keep them for a
programmable length of time. 

Rdadmin->manage_hosts->backups to configure this. 

Obviously rdadmin also has direct backup and restore buttons (which
should also now work with dbs named other then Rivendell), for when you
need a backup NOW.
