It all depends upon how much downloading/deleting/downloading you are doing. Every time you do that, time machine makes and maintains a copy of the new data unless this is done in a file it isn't allowed to back up. If you are pushing the limit of your hard drive, and going through data spin cycles, it isn't surprising at all that time machine is filling up your external. The back up drive should be significantly (let's say 2-3 times for typical use) larger than the hard drive it is backing up. This will not prevent time machine from filling the drive, but it all but guarantees that you will have a functional backup of things that are important...
