This has started happening since upgrading from OS 15 to 15.1. I get a message that the backup could not be completed, as below. No idea what "files unavailable means" or why it stops when the Mac is not awake. Once awake, I resume and it backs up as normal, so what's going on?

log out and log in that solved it immediately for me. updated today to 15.1.1 and the problem was back. loged out and in and now time machine is working again. Don't just turn the computer off. Log out while open and log in again.
