Lee,
If I remember right there was a discussion previously that suggested the newer Apple computers Apple¡¯s SSD¡¯s, ?no longer had to have their directories rebuilt. ?True? ? If so & an SSD TimeMachine is attached would it still have to be rebuilt as needed??
Thanks,
John

My experience with Time Machine is that this always happens sooner or later. The only fix I¡¯ve found is to nuke the backup and start over.
I¡¯ve stated several times before that I don¡¯t trust Time Machine. My reason is because Time Machine is clearly designed to work like a standard Unix/Linux backup utility called rsync. The problem is that rsync depends heavily on another Unix/Linux feature called hard linking. This hard linking is a capability built into Unix/Linux file systems. The Mac¡¯s HFS+ file system had no hard linking, so the Apple elves grafted it on just to make Time Machine work. It¡¯s always been somewhat flakey and my theory is HFS+ seems to get confused when there are too many links in a directory.
The new Mac file system, APFS, does do hard linking, so I expect there will soon be an APFS version of Time Machine.
