Hi All,  
I am using an Elastic search of 9 nodes which includes 2 data nodes. I am facing an issue like if one data node goes down .the all the data will be lost .there I a,m not getting any backup data.  
what I am thinking is like in two data nodes if one goes down others will take care as a backup.
