Our cluster has not been backup since the beginning of the year. I ran the API to backup all the indices as listed below it took 19 hours, lots of data. I am planning to run the backup on a daily basis going forward. How would I make sure it does not backup the same indices over and over and taking lots of disk space? 2nd question, does the snapshots names need to be unique when I ran backup on daily basis on can I use the same name eg. snapshot_abc_2015
curl -XPUT "localhost:9200/_snapshot/s3_repository/snapshot_abc_2015?wait_for_completion=true" -d '{
"indices": "abc-2015.*",
"include_global_state": false }'
