It does not provide a complete copy of the index information, it only 
dumps general information about the index plus the stored fields of 
documents. Non-stored fields are not available. There is no counterpart 
tool to take this XML dump and turn it into an index.

I'm working on a tool like what you had in mind, and I will be 
presenting results of this work at the Eurocon in Barcelona. However, 
it's still very much incomplete, and it depends on cutting edge features 

In any case, if you're using Lucene then you can safely take a backup of 
the index if it's open readonly. With Solr you can use the replication 
mechanism to pull in a copy of the index from a running Solr instance.
