Because the start windows are different, NBU does not associate these
backups with each other and treats them independently.

Okay.

Why do you have different start windows?

If the start windows are identical, Netbackup will do what you want.

Or, you can take out a day of incrementals that matches up with the
fulls so that they don't kick off that day.  Since you're doing weekly
fulls, that should be pretty easy.
