Sorry if this question is elementary: we need to preserve index data from time to time so we don't have to reload the whole index from scratch.
How do I do that exactly!? Which portion of the /data path do I need to preserve so I could just restore it back to a given point in time without ill effects?!
We just have one node right now, the path looks like this on RHEL:
/elasticsearch-2/data/elasticsearch/nodes/0/indices
Can I just tar up all of the contents below and restore them if needed?
