Backing Up Loopback File System Directories

Back up and restore loopback file systems (lofs) from the global zone only, to avoid multiple copies. Do not back up the loopback file systems of non-global zones.

If you back up and restore read/write loopback file systems from within a non-global zone, these file systems are then also writable from the global zone and from any other zones in which they are read/write mounted.
