I do restore my VMs to deplicate VMs to test from time to time (it’s pretty easy with Proxmox) but I use Restic for data backups which encrypts the data before uploading it, so one should restore a backup to a different folder to ensure the data integrity and that you didn’t forget your keys ahah
You don’t have to do it every week or month, but it’s worth doing it a few times a year or when you change something!
I have a similar (if not the same) error and I tryed everything without success. I can boot from the SD card but the SD card reader isn’t recognized by the OS. (I have two identical servers and the other one, which has no issues, is able to read the SD from the OS)
Not an issue for me, just sad that I know have a permanent warning and cannot boot in IntiligentProvisionning, which I don’t use anyway
