NFS Full Restore¶
The procedure herein details the steps that are required to perform a full cross-cluster Disaster Recovery restore of an MSR 4 instance, leveraging Velero and MinIO to perform a complete end-to-end backup. This method is intended for scenarios wherein both the Kubernetes configuration and all registry data (blobs) must be migrated to a separate cluster, regardless of whether the underlying storage is shared.
Mirantis recommends using this approach only for small MSR 4 instances, as it requires that you copy all registry data (image blobs) into and out of the MinIO backup storage, which is time-consuming and resource-intensive. Full backup and restore is recommended only for MSR 4 instances that have a small total size of image and artifact data. For production environments with large registries, use the NFS Metadata Restore to a different cluster method.
Prerequisites¶
Verify that your Kubernetes cluster is configured with a compatible CSI driver. For Snapshot backup, the CSI driver must support snapshot operations for your storage provider.
