How about switching to incremental (from "full") backups? Even if all you do are level-0 backups?

My understanding of the difference between a "full" and a "level-0" backup (besides the obvious impact on any subsequent level-n incremental backups) is that level-0 backups only back up database blocks that are currently in use, as opposed to "full" backups which back up all database blocks which have ever been used (i.e. no longer "unformatted").
