Disaster Recovery and Backup

In this chapter, we will focus on the backup and disaster recovery scenarios that keep applications in production highly available and allow them to quickly recover services during cloud provider or basic Kubernetes node failures. After following the recipes in this chapter, you will have gained the skills to operate the tools that are used for disaster recovery (DR) and be able to live-migrate applications across clusters and clouds.

In this chapter, we will cover the following recipes:

Configuring and managing S3 object storage using MinIO
Managing Kubernetes Volume Snapshots and restore
Application backup and recovery using Velero
Application backup and recovery using Kasten
Cross-cloud application migration ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
