How does snapshot and restore works in the background? For example - When a snapshot is taken with AWS S3 as backend store, what all oprations are carried out on elastic nodes and which nodes ? And which node is responsible for pushing the data to the S3 ? Similarly when we restore indices  
from a snapshot how are indices created from that and which nodes are doing what operation during that process?  
I tried to lookup this info but almost everywhere I found how to configure and use this feature and no info about internals.
