Be advised there are issues with snapshots of large filesystems. http://www.freebsd.org/cgi/query-pr-summary.cgi?category=&severity=&priority=&class=&state=&sort=none&text=snapshot&responsible=&multitext=&originator=&release= My experience shows that multiple snapshots of large filesystems, >30GB, causes the system to become unresponsive when a snap is created. If I limit the snapshot to 1/per large FS, then often the machine hangs on attempted reboots. -- Regards, Doug
