Abstract: A SSMA (Storage System Management Application) automates creation of a cloud provider on a cloud repository. The SSMA instructs a CTS (Cloud Tethering Subsystem) to create the cloud provider, which causes the CTS to establish a secure connection to the cloud repository. The cloud repository creates the cloud provider and returns identifying information. The CTS then tests the connection to verify that the cloud provider is reachable at the cloud repository. The SSMA also instruct a solution enabler to install the cloud provider in the storage system embedded operating system. The SSMA also implements a cloud provider synchronization verification process, which enables the SSMA to determine if there are any differences between lists of cloud providers maintained by the CTS and the embedded operating system. If any differences are detected, the SSMA automates the process of installing the correct set of cloud providers in the storage system embedded operating system.

Abstract: A storage array creates snapshots of each of a plurality of devices of a storage group associated with a production device on which active application data is logically stored. Metadata that indicates associations between the snapshots and the devices is stored on cloud storage with the snapshots as a snapset object. A program running on a management station used the snapset metadata to automatically create new devices on which to recover the snapshots on a selected storage array and uses the snapset metadata to cause the snapshots to be automatically written from the cloud storage system to the new devices on the selected storage array.

Abstract: Snapshot policy event logs are maintained containing timestamps associated with changes to the snapshot policy over time. Storage group event logs are maintained for each storage group associated with the snapshot policy containing timestamps associated with changes to the storage group over time. Snapshot compliance is calculated by creating a timeline of the snapshot policy and creating timelines for each of the storage groups associated with the snapshot policy. The snapshot policy timeline and storage group timelines are intersected to calculate how many snapshots should have been created for each storage group associated with the snapshot policy during each snapshot policy timeline interval. The sum of all snapshots that should have been created and still be maintained at a particular point in time is compared with an actual number of snapshots maintained for the storage groups by the storage system at that point in time.
