PROFILE
Shubham Pampattiwar
Sriram Pampatti contributed to the vmware-tanzu/velero repository by engineering advanced backup and restore features for Kubernetes environments. He developed object-level status restoration and PVC label-based volume filtering, enabling granular control over backup and restore operations. His work included designing and implementing VolumeGroupSnapshot support, allowing atomic multi-volume backups, and introducing configurable grouping and retention policies. Sriram’s technical approach combined Go programming, Kubernetes API design, and robust unit testing to ensure reliability and maintainability. He also addressed operational issues such as backup queue management and job toleration inheritance, demonstrating depth in both feature delivery and system stability across cloud-native storage workflows.

Jun 1, 2025June 2025 monthly summary focusing on key accomplishments and business impact for repository vmware-tanzu/velero. This month delivered Volume Group Snapshots (VGS) support in the PVC CSI backups, enabling back up of multiple PVCs as a single logical unit. Refactored the PVC backup flow to manage VGS creation, lifecycle, and cleanup, with a robust fallback to legacy Volume Snapshot paths. Updated CSI snapshotter client versions to maintain compatibility and performance. Implemented comprehensive unit tests for the VGS-enabled PVC backups to ensure reliability. These changes reduce backup complexity and improve protection coverage across multi-PVC deployments.

May 1, 2025Month: 2025-05 — Velero (vmware-tanzu/velero) delivered a configurable enhancement for VolumeGroupSnapshot backups, enabling PVC grouping by a label key and improving reliability and observability. The changes introduce a default label key, integrate grouping into the backup flow to include related PVCs in the same group, and enhance logging for edge cases. This work establishes deterministic, label-driven grouping for multi-PVC backups and supports future scalability and easier troubleshooting.

Feb 1, 2025February 2025 – Velero: Delivered two feature-focused updates that strengthen data protection governance and restore fidelity, with accompanying documentation and test coverage. Object-Level Status Restoration Documentation enables per-object annotations to override global restore settings, including precedence rules and practical usage examples, improving restore predictability. PVC Label-Based Volume Policy Matching extends the policy framework to match on PVC labels, updating data structures, matching logic, and tests to support granular volume actions driven by PVC metadata. No major bugs reported in this period. Overall, these efforts improve reliability, user control, and automation readiness, reducing manual intervention and enabling clearer guidance for operators.
