Thanks, Helix,

That clears some of this up for me.  I'm still a little mystified by what 
you say about backing up the Solr authority index.  I know that Solr 
indexes are just files.  I'll have to learn how to back up and restore of 
Solr indexes.

When you say you can deduplicate with CSV export, do you mean a CSV export 
from Solr?  How would you get the CSV back in to Solr?  Again my ignorance 
of Solr may be showing.

As I understand the DSpace metadata export and import via CSV, there is no 
provision for specifying authority values.  That would be an "unattended" 
submission, which then has to be corrected via metadata editing in the UI.  
Metadata editing in the UI is the only method I've been able to find for 
deduplicating authors.
