Adrian,

We mostly use collocation by group for this issue, but we have upon occasion
done as you suggest and have run a selective to consolidate a particular
client's data.  We have also renamed filespaces which forces a "full"
incremental.  When we do this, we include the date (as in
\\mynode\c$_20090205) so we can look back after a couple of months and
discard the old filespace.

Bob.

Richard,

I'm mainly concerned about the Offsite volumes. We have a small library
(IBM 3583) and a limited budget, so I was hoping for a simple
work-around to this issue. Never mind - I guess we'll just have to live
with it.

Best Regards,

Adrian -

The key word "collocation" does not appear in your question.  That's the
architectural solution to keeping related data together.
Collocation is conventionally used for onsite volumes, but not for
offsite volumes, given the substantial tape management complications
that would occur with partially filled volumes: offsite volumes are
usually not collocated, for that reason - but could be.
