Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Snapshots Lifecycle Management

The video tutorial covers the concept of Snapshot Lifecycle Management (SLM) in Elasticsearch, focusing on automating backups of clusters and indices. It explains how to set up repositories, define policies for snapshot creation and retention, and implement these in a practical setting. The tutorial also includes a section on integrating AWS S3 for cloud-based storage of snapshots, providing a comprehensive guide to managing data backups effectively.

What is the primary purpose of Snapshot Lifecycle Management (SLM) in Elasticsearch?

• To automate data backups

• To enhance search speed

• To improve data visualization

• To manage user access

Which type of repository requires configuring multiple nodes to access the same file system?

• Google Cloud Storage

• AWS S3

• Shared file system

• Local file system

What is a key feature of snapshots in Elasticsearch?

• They are stored in RAM

• They are incremental

• They are full backups

• They are deleted daily

What does the 'expire after' parameter in SLM policies define?

• The time to create a snapshot

• The time to delete a snapshot

• The minimum number of snapshots to keep

• The maximum number of snapshots to keep

What does the 'min count' parameter in SLM policies specify?

• The minimum number of snapshots to keep

• The maximum number of snapshots to keep

• The time to create a snapshot

• The time to delete a snapshot

What command is used to restart Elasticsearch after configuration changes?

• sudo system control status

• sudo system control restart

• sudo system control stop

• sudo system control start

What is the first step in setting up an AWS S3 repository for Elasticsearch?

• Create an IAM user with S3 permissions

• Install Elasticsearch on AWS

• Configure Elasticsearch YAML file

• Create a local directory

Which plugin is required for Elasticsearch to work with AWS S3?

• Repository S3

What is the purpose of adding secret keys to Elasticsearch's keystore?

• To enhance search speed

• To secure access to cloud services

• To improve data visualization

• To manage user access

What is the significance of using a unique bucket name in AWS S3?

• To ensure data encryption

• To avoid conflicts with existing buckets

• To improve data retrieval speed

• To manage user access
