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 script.  One of the ways to get a really slow
clone is to write your initial backups multiplexed to a tape, then do
nonmultipliex (single ssid) clones.  It'll take far longer to clone than
backup.

You don't mention exactly what you're doing or any other observations,
so that's just a guess.

18 TB / 4 days => 52 MB/s, correct?  That's not shabby depending on
your technology.  You may not need any help.  :-)
