OS 10.15.5 + Time Machine incompatibility
Since the OS update to 10.15.5, I've been getting failed TM backups (I have 2 in the apartment and they're both failing with the same error).
The message I get is "Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you."
Neither of my machines are actually backing up on TM, instead this loop of error/retry/error happens.
