Key Concepts for DR in Elasticsearch
- Snapshots: Elasticsearch allows you to take snapshots of your indices, which can be stored in a remote repository for backup purposes.
- Backup Repositories: Snapshots are stored in repositories, which can be set up on various storage solutions like AWS S3, Google Cloud Storage, or local file systems.
- Restoration: In the event of data loss or corruption, snapshots can be used to restore indices.
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.
