what are you amazed about exactly?
The instant snap is still an instant snap - nothing in this thread
changes
that. In fact it reinforces the concept with the statement "copy is
immediately available before the physical tracks are copied".
You really don't understand this stuff, do you.

I am pretty sure I understand it in my frame of reference. I think
the "instant" is flat out *WRONG*. As Bruce and others indicate the
data can take some time to completely copy. Leaving your "instant"
somewhere yesterday that started and may take X amount of time to
*FULLY* complete .
I contend that the copy is not fully complete until the last byte has
been transferred from the primary.
If I understand your view as soon as "the process" (starts) its
complete, no?
I would not want to be responsible to management if a disaster struck
after you initiated the "snap short" Its just like any other backup
"procedure" it has to fully complete before you have a real copy.
