MythTV never does backups of the database, except it will attempt a 
backup before a database upgrade (which only happens when you install a 
new version of MythTV).  If the automatic, pre-upgrade backup fails, it 
will tell you--which means if you're doing a proper upgrade and have 
started mythtv-setup to let it do the upgrade, you will be notified with 
a dialog on screen; but if you start mythbackend on the master backend 
host and let it do the upgrade, you will be notified in a log message 
(meaning it's useless to you because you won't have time to back up the 
database yourself before it starts changing things).

So, normally, the mythconverg_backup.pl script is only run when the user 
runs it, and it reports the results as an exit code , which the user 
must verify.  So, if using a script to do the backup, have it check for 
a zero exit code (meaning no errors), or if running interactively, make 
sure you don't see any error messages in the console.
