Back up of Elastic Serach Data

Elastic Stack Logstash
1

Hi -

My ES is hosted on a Virtual Machine, receiving data from multiple nodes, Disk is reaching to the maximum with the data (indices).
I'd like to take the backup of last 30 days of data and purge it and move the backup data to a different machine
Is there any way to do this. Please let me know. Thanks !

The appropriate way to do so is with the Snapshot and Restore APIs.

If you're managing time-series data, then Elasticsearch Curator offers snapshot and restore actions to accomplish the same more easily.
