Testing Disaster Recovery
Regularly test your disaster recovery procedures to ensure that they work as expected.
Example: Restoring an Index:
Delete the Index:
DELETE /my_index
Restore from Snapshot:
POST /_snapshot/my_s3_repository/snapshot_1/_restore
{
"indices": "my_index"
}
Verify that the index is restored correctly and that all data is intact.
High Availability and Disaster Recovery Strategies for Elasticsearch
Elasticsearch is a powerful distributed search and analytics engine, but to ensure its reliability in production, it’s crucial to implement high availability (HA) and disaster recovery (DR) strategies. These strategies help maintain service continuity and protect data integrity in the face of failures or disasters.
This article will guide you through the key concepts, strategies, and best practices for achieving high availability and disaster recovery in Elasticsearch, with detailed examples and outputs.
