I am using Win 7 backup as described in Fren Langa's article, Build a complete Windows 7 safety net. It looks like it is making a complete backup every week instead of incremental backups as it has used almost half of a 1 tb drive in the last 5 months. Did I make a wrong setting and is there a way to delete the old backups? I don't see any individual files listed that I can delete.
