Index Snapshot

[Emil David]

Hi,

Use the below query to create/restore snapshots.

Can anyone explain the purpose of the below fields? If we are not adding these fields in the query what will happen, what is the advantages/disadvantages  when adding this field.

Checked the below ref docs, can we get more explanation about this?

  "include_global_state": false 

PUT /_snapshot/elasticsearch/snapshot-1

{ 

  "indices": " wazuh-archives-4.x-2024.01.01", 

  "ignore_unavailable": true, 

  "include_global_state": false 

} 

POST /_snapshot/elasticsearch/snapshot-1/_restore 

{ 

  "indices": " wazuh-archives-4.x-2024.01.01",

Hi Emil,

Thanks for waiting.

There are the below use of these parameters.

ignore_unavailable: If an index from the indices list doesn’t exist, whether to ignore it rather than fail the snapshot. Default is false.
include_global_state: Whether to include cluster state in the snapshot. Default is true.

You can learn more about the snapshots and its parameters.

I hope this information is helpful to you. Please feel free to contact us if you have any questions.

Hi,

Thanks for your reply.

What is the cluster state?

What is the difference between the snapshot whether include_global_state:  true and include_global_state:  false?

include_global_state:  true - what details will be additional? what are the advantages and disadvantages? Please explain

include_global_state:  false - what details won't be there? what are the advantages and disadvantages? Please explain.

include_global_state: The default value is true. Would there be a problem with a snapshot if we changed it to false?

Can we take the snapshot/restore without the include_global_state value as mentioned below?
