He has two pools: backup and zroot. Only backup is visible. So he shouldn't do as you suggested, because it will rename his backup pool to zroot, which will bring the confusion, because it is not the original zroot pool. To be able to import his original zroot pool, it needs to be visible to "zpool import" as a first step.
