VMware vSphere Kubernetes Service (VKS), formerly known as Tanzu Kubernetes Grid (TKG) Service, has emerged as a popular platform for enterprises deploying containerized workloads, particularly those that rely on vSphere Kubernetes release (VKr), previously referred to as Tanzu Kubernetes release, for their cloud-native infrastructure.
The native vSphere Kubernetes Service backup and disaster recovery tool, Velero, is often used as an open-source solution for backing up and restoring Kubernetes resources and persistent volumes.
However, implementing Velero within VKS environments often requires significant configuration and manual operation, and it still leaves certain gaps that can be better addressed with advanced solutions like CloudCasa.
Configuring Velero for VMware vSphere Kubernetes Service Backups
Velero, while powerful, is not plug-and-play. It can be very complex to set up and maintain. Configuring Velero for Kubernetes backups in a VKS environment involves multiple steps:
Setting Up a Storage Backend
- Set up credentials with appropriate IAM permissions.
- Install Velero with the –bucket and –provider parameters to connect to your object storage.
Customizing Backup Resources
- Define Backup and Restore objects to specify namespaces, resources, and volume data for protection.
- Schedule regular backups using Velero schedules.
Restoring Applications
- Create Restore objects to pull data from stored backups.
Challenges with Velero
- Complex Setup and Management: Configuring Velero requires considerable expertise in Kubernetes, YAML, and cloud storage integration.
- No Support for Immutable Backups: Velero lacks support for immutable backups, leaving data vulnerable to ransomware and accidental deletions.
- Scaling Limitations: Velero struggles to handle large-scale Kubernetes environments, as it doesn’t support parallel backups within a cluster.
- Data Risks: Velero backup storage locations are not shareable, and attempting to share one across multiple instances or clusters can lead to metadata conflicts, retention policy issues, and potential data loss or corruption.
- Manual Intervention: Restoring applications often involves manual steps, particularly for large or complex PVs.
- No Central Management: Managing backups across multiple clusters requires additional tooling or custom scripts.
