I think maybe the dba module [1] could use some love to add an export 
function.  The tables for the site would then be Drupal controlled 
which gives the benefit of not dealing with tables from other sites.  
It will already do a backup for you but from cron.php.

Of course, but the more databases the more database processes you also 
have so you also need to concern to the CPU power and memory limits of 
the host.
