Time Machine in Catalina 10.15.three has serious bugs : apple
The #1 drawback individuals have with Time Machine has to do with a failure of Time Machine to have the ability to acknowledge listing construction adjustments. I hope in some unspecified time in the future Apple addresses this, however for now the issue turns into one the place if excessive up on the listing hierarchy, a change is made, Time Machine considers all the pieces under that to be new.

Time Machine sees that as a brand new listing of recordsdata and wishes to have the ability to write that earlier than deleting earlier archives. This is why the Time Machine drive will generally have to be erased and begin over.
