Yes, that's the ticket. Thanks! I do find it interesting, though, that
something like nsrim would not be used for at least part of this
operation since according to the man pages, nsrim is really the tool for
managing the indexes and nsrmm is for managing the media. And, after
all, we're not talking about removing the saveset from the actual media
itself but rather the index entry, so you'd think that nsrim would be
the tool that would provide this capability for removing the index
entry, and maybe nsrmm would be used if you wanted to delete the media
entry from the media database, but I guess Legato decided to just bundle
both of those options under the same tool. Of course, it would be cool
if NetWorker provided a way to remove the actual saveset from the media
itself, in addition to the index entry, without removing the other
savesets on the media. This would allow you to at least re-claim your
space. but I guess that would be tricky and time consuming since it
might involve de-multiplexing the affected data.
