do not bother w/legato support, and emc still does not know the product so
they are not a resource (yet). i have had a case open w/legato on this issue
since 3.11, and believe me, this list is a much better resource. we are
running v6.1.3 in a w2k environment. the first thing we did was upgrade from
6.1.2 -- no change in clone speed. what seemed to help, slightly, was
changing target session down to 1 on tape devices. other than this, legato
has been no help. there is also another couple threads on this list to read.
