I am confused on backup and restore process, can someone please help?

Elastic Stack Elasticsearch
1

Hi Team,

I have single node elastic cluster and my indices are getting created everyday. I do close them manually every after 120 days. So once index is closed would it be possible to take a a backup of those? Or is there any way where I could dump the indices in any other format like json or in file and store it somewhere so that disk space can be freed?

Also what if later I need to restore the that json file what is best method?

Thanks

it is useful to use snapshot and restore feature to backup your data to HDFS or NAS etc.
Together with Index Life Cycle Management(ILM) would make this automatically.

You should look at index lifecycle management and snapshot lifecycle management.

See

And

And if you have a commercial license, you can even search in the snapshots without needing to restore them...
