curtisi, thanks for the explanation. That makes sense.
What about the backup archive. Could that be a mechanism to extend retention? I'm aware that you can't merge the archive back into the live data. So is it possible to search the archive using the console? If so, how would one do that. I'm having trouble finding a knowledgebase article on this.
Also, what would be both the performance and storage impact be compared to simply expanding LEM's volume?
