Mentioned was a pretty fundamental issue with time machine, to this day. In that it doesn't (de)allocate older backed up space to make for up space for newer back ups. This or some variations of that. The bug may not always manifest itself I suppose which makes it worse emotionally. I'm there setting on a 1tb backup disk dedicated to backup a 500GB root HDD, it keeps saying there isn't enough space available after 1h sorting out what needs copied over. Deleted a series a snapshot but it won't tell what doing this is saving me. I can only resort to wipe the entire backup and backup again. Now wondering, what if I deleted some documents a while back which I thought would have a snap. Do I care more about getting a fresh backup or unweilded snapshots that may or may not contain something I don't know I've lost.
