I am trying to get my head around some feature/capabilities for elastic  
search vs mongoldb and other document stores.

1. What is the storage overhead for a local deployment? how many copies?  
If I use it as the primary store, what are the protection guarantees?
2. Does it have ability to do geo-protection? if yes, how many sites?
3. Does it have ability to access data from multiple sites?
4. I saw there are snapshots, but whats the limit on number of snapshots  
that can be taken? can i rollback a specific document and not entire  
cluster if i take a snapshot at cluster level?

Some deployment related questions:  
How many nodes does it scale to? any limits?  
what is the preferred spindle size? I saw it eats up a lot of memory, but  
I assume it prefers SSDs or 1 TB drives larger than that how it would  
perform?
