Application Mobility

Container Storage Module 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 object storage to copy application metadata and data. When a backup is requested, it uses these options:

• Volume Group Snapshots : If enabled, crash consistent snapshots of all volumes are used.
• Volume Snapshots : If enabled and supported by the CSI driver, individual snapshots are used for each Persistent Volume.
• Full Copies: If no snapshot options are enabled, full copies of each Persistent Volume are used.

After a backup is created, it can be restored on the same or any other cluster(s) if:

• 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.
