Since files are pooled, there's really no downside to you doing full
backups every 7 days and incrementals every night, and just increasing
your retention periods to something you can live with.

If you're going to keep all those incrementals, I wouldn't recommend doing
full backups any less frequently than every two weeks or so, which is
often the point at which they become as slow or slower than full backups.
