I wrote my own backup process in a procedure. It isn't as robust as Ola's maintenance script, but it does everything I need and I can support it. There's a database job to run log backups and one to run full backups. The procedure accepts parameters to determine the backup type.

I haven't had the need to take it to this level yet, but if you take this route, you could write a table-based scheduler that determines when and how to backup each database. Just an idea.
