I was looking for feedback on how you do cloning. We have a rather large environment and takes us 4 days to complet cloning. We clone about 18TB. We only have one pool and clone all the FULL save set
When cloning, are you reading and writing from the tapes an an "appropriate" speed (I use iostat to confirm)? Are you handing nsrclone a volume or savesets? One or a list? You mention a home grown s

I used to have the same problem, and to fix it I've written a fairly basic script that tries to separate out ssid's for parallel cloning to help remove "tape dependencies"...for example, if the clone
