Aha, don’t read way up top. A dead Mac was also the problem in the other thread.
Probably not. It’s still a Time Machine backup library, although once removed.
Three’s no good solution for this. In the other thread the problem with a Time Machine backup was immediately apparent and probably would be here also. The other danger is that any problem with a restore won’t show up until down the road and then as an unusable corrupted library.
My final reply in the other thread was -
It still holds.
Tagging @support, just in case.
