Indeed. This falls under the well-discussed topic of "how to duplicate the pool." See any the archives of this list, any random month. Short answer: it's not fun. If you really want to archive the entire pool and pc structure, I suggest burning a binary copy of the unmounted pool filesystem to the Blu-ray disk. Make an LVM snapshot, unmount the snapshot, then use dd to make a binary copy to the blu-ray ISO filesystem. If you want to recover from this, dd it back, or mount it with "mount -o loop".
