I have my system make a full backup created nightly right before a nightly reboot. (running HA 2021.5.5 core)…suddenly, it reboot itself into safe mode with OODLES of errors.
I tried a full backup, it appeared to complete successfully–nothing. Re-rebooted into safe mode. Even a couple days older’s (wonderful grammar, right?..lol) reboot–nothing.
Unfortunately, my knowledge base cuts off at decoding several of these errors. My bigger question/misunderstanding is if it was working fine on 6/12 and rebooted fine since then, how come all of a sudden these errors are showing even after restoring that 6/12 backup?
