From Agent-Based to Agentless - Scalable VM Backup and Restore for Large-Scale KubeVirt Deployments

Learn how to design and implement scalable agentless VM backup and restore frameworks for large-scale KubeVirt deployments in this 20-minute conference talk. Discover the transition from agent-based to agentless backup models through real-world experience from one of India's largest telecom providers managing 100+ geographically distributed data centers, 3,500+ physical servers, and 50,000+ virtual machines. Explore the trade-offs between agent-based and agentless backup approaches and understand why agentless models prove superior for KubeVirt at scale. Master how to leverage KubeVirt's APIs, snapshots, and volume integrations to implement automated agentless backup solutions. Examine lessons learned from migrating from agent-based approaches to hypervisor-driven, API-first backup strategies. Understand how to design high-throughput, incremental backups that minimize impact on VM workloads in distributed clusters. Learn strategies for implementing application-aware backups using declarative automation and orchestration without requiring per-VM agent installations. Gain insights from real-world operational experiences, performance tuning techniques, and failure recovery strategies deployed at nationwide telecommunications scale. Acquire practical knowledge for architecting reliable, low-touch VM backup and restore processes in KubeVirt for production-scale deployments while reducing operational overhead and maintaining application-level data protection.
