6.) LUN B gets attached and imported on a backup server where BakBone's Netvault streams all data in the zpool to tape.
7.) LUN B gets exported and detached from bkup host.
8.) LUN B gets mapped/attached/imported on MySQL DB server #2 (secondary machine). 
9.) ibbackup --restore is run against MySQL instance sitting on zpool on LUN B.
10.) MySQL is starated on LUN B on secondary machine, and apply binlogs to bring up-to-date.
