This project automates backups / replication of (rook) ObjectBucketClaims onto other rook Object Bucket Claim targets. It is designed to be run as Kubernetes Cron Job.
This tool fetches all OBC objects from the Kubernetes API, creates target OBCs on the target cluster and mirrors all files from the source cluster to the target cluster. It creates all OBCs at the target cluster within TARGET_BUCKET_NAMESPACE and uses the following naming scheme:
${TARGET_BUCKET_PREFIX}-${OBC_NAMESPACE}-${OBC_NAME}.
This program is configured via environment variables.

| TARGET_S3_URL | Public reachable endpoint for uploading the S3 files | https://target.example.com |
| TARGET_KUBECONFIG | Path to kubeconfig for target cluster, empty for in-cluster-auth. | target_kubeconfig |
| TARGET_BUCKET_PREFIX | Prefix used for target buckets | prefix |
| TARGET_BUCKET_NAMESPACE | Namespace for Rook OBC resources | rook-ceph |
| TARGET_STORAGE_CLASS_NAME | Storage Class Name for Rook OBC resources | spinning-rust |
