We are using Elasticsearch 1.7.2 in Prod and having 3 master nodes, 3 data nodes & 1 client node. ES cluster has 3 indices such as,
Index name Primary size Shards
es_chr, 2 GB 1
es_cval 173 GB 6
es_item 850 GB 18
Yesterday we took snapshot in Production cluster and I can see in repository snapshot files/folders were generated with based on the number of shards allotted and then we restored the indices in DR(Di aster Recovery) cluster for backup purpose. Restoring in DR cluster, I manually moved the snapshot files from PROD to DR server (through SCP) and I started restoring it and process were completed well. Suppose today If i am going to take snapshot of index es_item, data might be changed or new data will be added in index.
Should I again manually need to move snapshot files from PROD to DR server for backup?
Is there any other workaround to move incremental data?
How to find the difference between initial & incremental snapshot?
Please kindly help me in this..
