Yeah, there aren't really any.  The only "Automatic" backup we have at 
this point is the pre-DB-schema upgrade backup.  Therefore, a user who 
upgrades from 0.21-fixes to 0.22-fixes will get a DB backup right before 
the upgrade(s) (before the TV schema upgrade by mythtv-setup/mythbackend 
and before the MythVideo and MythMusic schema upgrades done by 
mythfrontend) and will never get any more automatic backups.  The 
setting you've found is to disable the pre-upgrade backup (and, IMHO, 
disabling those is not a good idea--in spite of what the people who 
complained about those pre-upgrade backups might think).

Some (most?) distros, however, include automatic backups or you can 
always use http://www.mythtv.org/wiki/Database_Backup_and_Restore .

Sorry, I haven't gotten that far, yet.  We need a /lot/ more 
infrastructure to prevent automatic backups from corrupting the DB or 
recordings.  It's on my TODO--just might be below a much bigger job that 
will actually make the auto-backups /much/ easier.  :)
