Priit, Thank-you for addressing a significant backup/recovery shortcoming. I've used biba extensively, however if files/directories are backed-up with MLS+biba and recovered in a biba only environment, that is the sysadmin choice. Warning messages are fine, but the restoration should continue (if possible).
