Hi there.
As I said in the first comment. The problem is about restoring, no making a backup.
The backups had always been there , but it’s impossible to restore.
I tried again, this is the error code: BMI-Gb4yEdUq-13212
And this the debug info you asked before, but updated with the last backup tried
