Thanks, and that backup can simply be copied to a spare flash?
My mistake, I ment that the appdata is stored on the cache drive, not flash. But the template (and therefore the container settings) is stored on the flash if I understand you correctly, thats why I need to set them up again.
I'm not using a parity drive, I'm using a cloud backup solution for the data drives. So I can conclude that it's not that important to assign the drives to the correct slot?
