K8Up

K8Up is a Kubernetes-native backup and restore operator that automates backup, archive, and recovery workflows for stateful workloads running on Kubernetes clusters (data protection / backup automation).

  • Kubernetes operator for scheduling and managing application-consistent backups of persistent volumes (data protection).
  • Supports backup, restore, archive, and check operations through Custom Resource Definitions (CRDs) (Kubernetes extensibility).
  • Integrates with object storage backends via Restic-compatible repositories for storing backup data (storage and backup repositories).
  • Namespace-scoped and cluster-wide configuration for multi-tenant and shared platform setups (multi-tenant platform operations).
  • GitOps- and automation-friendly design using declarative CRDs and Kubernetes APIs (infrastructure as code).

More About K8Up

K8Up is an open-source Kubernetes operator designed to provide automated backup, archive, and restore capabilities for applications that rely on persistent storage in Kubernetes (data protection / backup automation). It addresses the problem of managing consistent and repeatable backups of stateful workloads in containerized environments, using Kubernetes-native APIs and concepts rather than external backup scheduling systems. The project targets platform teams and operators who need to enforce uniform backup policies across clusters and namespaces while retaining compatibility with standard Kubernetes workflows.

At its core, K8Up extends Kubernetes through Custom Resource Definitions (Kubernetes extensibility) that model backup-related operations as Kubernetes resources. The primary CRDs include definitions for Backup, Restore, Archive, Schedule, and related configuration objects. These resources allow teams to declare backup jobs, retention rules, and schedules in YAML, which K8Up then reconciles and executes via its operator control loop. Because these CRDs are standard Kubernetes objects, they integrate with existing tooling such as Git-based configuration management and Continuous Integration and Continuous Deployment (CI/CD) pipelines (infrastructure as code).

K8Up commonly works with Restic-compatible repositories (storage and backup repositories), enabling data to be stored in object storage systems such as S3-compatible services or other supported backends. The operator orchestrates backup jobs against persistent volumes, coordinates snapshot or file-level backup operations via Restic, and records status and metadata back into Kubernetes resources. It also exposes restore workflows that reference existing backups and rehydrate data into target volumes, as well as archive and check operations for lifecycle management and integrity verification.

In enterprise environments, K8Up is deployed into Kubernetes clusters to centralize backup policy across namespaces, teams, and applications (platform operations). It supports both namespace-scoped and cluster-wide configurations, which allows platform operators to offer backup as a service to application teams while retaining central governance. Declarative scheduling via the Schedule CRD enables standardized backup windows and retention strategies, and events or status updates are surfaced via Kubernetes mechanisms for integration with logging and monitoring stacks (observability integration).

From a technical taxonomy perspective, K8Up fits into the categories of Kubernetes operators, data protection tooling, and backup orchestration frameworks. It operates entirely via Kubernetes APIs, making it suitable for GitOps workflows, multi-cluster management platforms, and environments where backup configuration must be versioned and auditable. Its focus on object storage backends and Restic-compatible repositories positions it for cloud-native deployments where backup data typically resides in remote or cloud object stores.
