Hi David
I can confirm that I was able to do a Debug Full Backup way back when the site only a few images confirming what you have just described. I am on a shared server at present but I could move to a VPS server with 123-Reg (that does activate wp-cron). I can stand the extra cost but the migration freaks me out. Presumably I would have to use WP Export and then Import. Are there any pitfalls that I should be aware of?
