NOTE: This tech-preview release is not intended for use in production environment.
NOTE: Application Mobility requires a time-based license. See Deployment for instructions.
Container Storage Modules for Application Mobility provide Kubernetes administrators the ability to clone their stateful application workloads and application data to other clusters, either on-premise or in the cloud.
Application Mobility uses Velero and its integration of Restic to copy both application metadata and data to object storage. When a backup is requested, Application Mobility uses these options to determine how the application data is backed up:
- If Volume Group Snapshots are enabled on the CSI driver backing the application’s Persistent Volumes, crash consistent snapshots of all volumes are used for the backup.
- If Volume Snapshots are enabled on the Kubernetes cluster and supported by the CSI driver, individual snapshots are used for each Persistent Volume used by the application.
- If no snapshot options are enabled, default to using full copies of each Persistent Volume used by the application.
After a backup has been created, it can be restored on the same Kubernetes cluster or any other cluster(s) if this criteria is met:
- Application Mobility is installed on the target cluster(s).
- The target cluster(s) has access to the object store bucket. For example, if backing up and restoring an application from an on-premise Kubernetes cluster to AWS EKS, an S3 bucket can be used if both the on-premise and EKS cluster have access to it.
- Storage Class is defined on the target cluster(s) to support creating the required Persistent Volumes used by the application.
