The database backup script is something I /can/ help you with (and feel 
free to step back into IRC if that was you in there earlier--I'm sphery 
in there).

What, specifically is the problem with it?

If it's a lack of Perl support on your system (I don't know what oS11.1 
is), you can always run the backup script from any other system with 
Perl and the MySQL client tools installed (i.e. an Ubuntu LiveCD or your 
frontend system).  You don't need to run it on the same host running the 
database server.

See, also, http://www.mythtv.org/wiki/Database_Backup_and_Restore .  The 
first section ( 
) includes directions for downloading an up-to-date copy of the backup 

If there is a problem, I'd love to fix it, so I'd appreciate your feedback.
