Learning Elastic Stack 7.0 - Second Edition

By: Pranav Shukla, Sharath Kumar M N

Overview of this book

The Elastic Stack is a powerful combination of tools that help in performing distributed search, analytics, logging, and visualization of data. Elastic Stack 7.0 encompasses new features and capabilities that will enable you to find unique insights into analytics using these techniques. This book will give you a fundamental understanding of what the stack is all about, and guide you in using it efficiently to build powerful real-time data processing applications. The first few sections of the book will help you understand how to set up the stack by installing tools and exploring their basic configurations. You’ll then get up to speed with using Elasticsearch for distributed search and analytics, Logstash for logging, and Kibana for data visualization. As you work through the book, you will discover the technique of creating custom plugins using Kibana and Beats. This is followed by coverage of the Elastic X-Pack, a useful extension for effective security and monitoring. You’ll also find helpful tips on how to use Elastic Cloud and deploy Elastic Stack in production environments. By the end of this book, you’ll be well-versed with fundamental Elastic Stack functionalities and the role of each component in the stack to solve different data processing problems.

Backing up and restoring

Taking regular backups of your data to recover in the event of catastrophic failures is absolutely critical. It is important that all of your data is saved periodically at fixed time intervals and a sufficient number of such backups are preserved.

A common strategy is to take a full backup of your data at regular intervals and keep a fixed number of backups. Your cluster may be deployed on-premise in your own data center or it may be deployed on a cloud hosted service such as AWS, where you may be managing the cluster yourself.

We will look at the following topics on how to manage your backups and restore a specific backup if it is needed:

  • Setting up a repository for snapshots
  • Taking snapshots
  • Restoring a specific snapshot

Let's look at how to do these one by one.
