I have the needs to backup data and dump data from production environment to stage.
The size of one index is about 20G.
I've tried using elasticsearch-dump but it is too slow.
And I also try to use snapshot but have difficulties in renaming the index.
I know snapshot may restore data with the same index to other cluster easily but not sure if this could also restore data to new index on the same cluster.
Does anyone have a better solution or how to do it?
Thanks in advance!
