Part2: Kubernetes Backup on Managed Services: What Changes When You Use EKS?
- When using managed Kubernetes services like Amazon EKS, the backup strategy shifts to focus on Kubernetes objects, persistent data, and application configurations.
- Managed services like Amazon EKS handle the control plane, including etcd, making traditional etcd snapshots unfeasible.
- For backing up on EKS, focus on Kubernetes objects, persistent volumes, networking, security, and application data.
- Velero is recommended for Kubernetes object backup on EKS, supporting scheduling, retention policies, and integration with AWS S3.
- Use Velero for backing up persistent data, including EBS volumes, and automate backups with regular testing for validity.
- Security measures such as encryption, immutable backups, multi-region storage, and access controls are crucial for backup on EKS.
- Consider cost-saving strategies like storage tiering, incremental backups, and retention policies for managing backup costs.
- The control plane/etcd and node-level state are typically inaccessible for direct backup on managed services like EKS.
- Best practices include using Velero for disaster recovery, automation for cost control, encryption for security, regular testing, and multi-region backups.
- Follow additional resources for backup and restore guidelines specific to Amazon EKS.
- Overall, leveraging tools like Velero and AWS storage features on EKS ensures a robust, cost-effective, and secure backup approach.
