B&R 10 will allow CDs and USB flash drives as recovery media but not USB disks. Can't figure out a reason as to why not. Especially with the usefulness of having the recovery program along with the backup on the same drive. Worth asking if anyone actually knows of a way to do that? This question had been sort of already asked before (https://www.wilderssecurity.com/showthread.php?t=265858), just in case it wasn't clear. For now I use a usb flash drive to boot and usb disk drive to restore... one too many. I have one disk setup working with clonezilla but I like paragon more though.
