After upgrading to Catalina, Time Machine backup data disappeared, though timestamps are there.
My backups have disappeared. I am connected on wired network to the disk. It works fine. I have over 400GB remaining on the 1TB drive. I can see the backups since 2/14/2020, but nothing before. Although I am able to see the dates of the previous backup on the timeline on the right of the Time Machine screen, just can't go to the date and see/restore data.
