Kubernetes-native backup operator for scalable, application-aware data protection

About K8up

K8up is an open source Kubernetes Operator designed to provide robust backup and restore capabilities within Kubernetes environments, including OpenShift. It enables cluster operators to efficiently manage backups of Persistent Volume Claims (PVCs) with various access modes and supports application-consistent snapshots by integrating with tools that output to stdout. K8up facilitates both scheduled and on-demand backups, archival to long-term storage solutions like AWS Glacier, and repository integrity checks, ensuring data reliability and availability.

Built on top of the restic backup tool, K8up supports multiple backup targets such as S3-compatible storage, SFTP, REST endpoints, and local storage. Its multi-tenant architecture allows self-service backup and restore operations across different teams or projects, making it suitable for large enterprises managing complex Kubernetes deployments. The solution is production-ready since 2019 and is maintained as a CNCF Sandbox open source project, emphasizing community-driven development and transparency.

Backup & Disaster Recovery

Evaluate Veeam, Commvault, Rubrik, Cohesity, Dell PowerProtect, and Druva against your real RTO and RPO targets — with ransomware resilience, not backup windows, as the deciding criterion.

Cloud Cost Management & FinOps

Compare IBM Apptio Cloudability, VMware Tanzu CloudHealth (Broadcom), Flexera One, Harness, Finout, Zesty, and Vantage on the question this category actually turns on — not whether a dashboard is pretty, but whether shared-cost allocation is accurate, committed-use buying is optimized, and engineering acts on the recommendations.

Cloud Infrastructure & IaaS

Compare AWS, Microsoft Azure, Google Cloud, Oracle Cloud Infrastructure, IBM Cloud, Alibaba Cloud, and DigitalOcean on the one thing the pricing calculator hides — egress, support-tier costs, committed-use discounts, and lock-in — not the on-demand compute rate the demo shows you.
