George,

Thanks making my thoughts clear. Currently, I clone using  nsrclone -s server 
-b pool -S -f file
My question was, would it be faster to clone with  nsrclone -s server -b pool 
volname

I think I will just try it and see.

Regards,
Guy

Subject: Re: [Networker] Faster Cloning. By saveset or volume?


I seem to recall that this got into this issue of de-multiplexing versus
maintaining the multi-plexing. Then again, that may be have been the
difference between running the nsrclone command with a list of saveset
ids (on the command line with -S or via an input file as -S -f file)
versus iterating over the list one at a time. I think if you iterate it,
the savesets would have to be un-multiplexed, but if you don't iterate
it one at a time then the multi-plexing is preserved. If that's true,
then it seems to me that cloning the entire volume would have to be
faster because it would not have to de-multiplex anything, but if you
did it by saveset, one at a time, then it would, unless you ran it using
an input file with all the savesets in there.

So, my question would be: is running nsrclone with an input file that
contains all the savesets tantamount to cloning the whole volume in
terms of over all time. In other words, which of the following is
faster:

nsrclone -s server -b pool volname
nsrclone -s server -b pool -S -f file

where file contains all the saveset ids on the volume.

I mean, both operations should amount to the same thing, but I'm
thinking that cloning the volume using the first command is easier and
could not be slower than the second.
