Installation and Configuration
Soaring have you run a thorough "Resize Item Images" in your Image Core module tools...for all site categories to reduce file sizes of images on your site to something reasonable like max 1000 pixels in any one direction, for instance? That can save many GB on your storage. Do you also have "convert to JPG" checked? You might also consider setting your delete image cache to like 3 or 7 days instead of 30, at least while these issues are going on for you.
