Interesting, but what's not clear is does it pick the dedicated
drives always for restoring unless of course, you initiate several
recoveries at once?

In other words, how can you prevent non dedicated drives from being
used ever for 'recoveries' and have every recovery done from
dedicate drives only.  Thanks.
