George,

I don't know about how you can determine ahead of time what directories will span 
multiple volumes but you can certainly go into Recover and select a directory to recover 
then check the "Show required volumes" display to see if in fact it does span 
volumes.  I don't imagine it would take too long to find one that did (but then what do I 
know?).
Yes, that's exactly what I'm looking for: a way to determine which
directories did in fact span tapes, NOT which ones will span tapes. So,
this is an "after the fact" question. I can certainly do as you
mentioned but was looking for a slick way to determine this without
trial and error?
Some of the save sets have a small number of top level sub-directories
so it won't take too long to find one that spans, but most of the save
sets have a lot of top level sub-directories, so that will take much
longer. Obviously, at least one of them must span two tapes.

Hi,

We have 19 save sets that we've just backed up. These have also been
cloned. Each of these save sets is 1+ TB and consist of a number of
smaller sized sub-directories, e.g. 300 KB, 2.4 GB, 19 GB, etc. The tape
pool is indexed. All of these save sets span multiple tapes (minimally
3-4 tapes) as they were multiplexed together (parallelism=4) during backup.

I'd like to run a browseable recover test (nwrecover or CLI recover) on
   a couple of random sub-directories from each save set, but I'd like
to also pick a few that span at least two tapes. I don't want to recover
the whole save set, however, as these are all very large.

Is there a way I can determine which directories span two tapes?

Will I have to just select random directories, using nwrecover or CLI
recover, until I find one that shows two volumes required?

Thanks.

George
