Snapshots Gone Wild: Taming Multi-PVC Chaos with VolumeGroupSna... Shubham Pampattiwar & Scott Seago

This talk features Shubham Pampattiwar and Scott Seago from Red Hat discussing the challenges of backing up multi-volume applications in Kubernetes and introduces the VolumeGroupSnapshot (VGS) API. The speakers explain how VGS allows for the orchestration of snapshots across multiple Persistent Volume Claims (PVCs) to ensure data consistency. They delve into the integration of VGS within Velero and various Container Storage Interface (CSI) drivers, showcasing how Kubernetes manages snapshot creation and recovery workflows. By presenting test results comparing single and group snapshots, the audience gains insights into the trade-offs and practical uses of VGS for achieving reliable backups without operational chaos.
