Backup channels

I am running Umbrel 0.5.3
My disk got corrupted from a hardware failure.
I started again from scratch: download blockchain, install lightning node, restore via umbrel backup.
However I could not close 4 channels.
This error message “cannot close channel with state: ChanStatusLocalDataLoss|ChanStatusRestored”
If I understand the message correctly, I took the wrong backup file and some channels are stuck in the wrong state.
Is there any other way to recover the correct backupfile?
I don’t have a local backup.

Trying this now:

I tried this today without success. How are you doing?

I wasn’t able to contact anyone who could provide me with the correct backup file. So no succes yet.

Did automatic backup files show up in your Umbrel node after you reinstalled and entered your 24-word seed?
