Hi i have a Prod ES Cluster ([elastic.co](http://elastic.co)) and a Staging one. i want to create a nightly process that sync the Prod cluster into Staging cluster so we will have updated data from prod. the way i want to do that is the following: - create a snapshot repository with GCS repo on prod (write mode) - Create a snapshot repository with the same GCS repo on staging cluster (with source only read only mode) - run snapshot on prod - restore snapshot on staging Question is regarding the 'global cluster state' and system indexes. how do i know if i should skip those as i only need the actual data? thanks CL ---
