Creating, deleting, and restoring volume snapshots in remote data store
A recently granted patent (Publication Number: US11921671B2) discloses a method for volume snapshot deletion in a container system. The method involves receiving a request to delete an individual volume snapshot stored at an object store separate from the source volume, identifying the corresponding volume snapshot object, marking it for deletion, and sending a delete request to the object store. This process is repeated until the individual volume snapshot is deleted. Additional steps include allowing the storage operating system to send the delete request, triggering a garbage collection process, and deleting the volume snapshot object post deletion of the individual volume snapshot.
Furthermore, the patent includes claims for a non-transitory machine-readable medium and a computing device configured to perform the volume snapshot deletion method. The machine-readable medium contains instructions for executing the deletion process, including identifying the volume snapshot object, sending delete requests, and delaying deletion of the volume snapshot object. The computing device, equipped with a processor and memory, executes the method by receiving delete requests, marking volume snapshot objects for deletion, and sending requests to delete unique objects related to the source volume or individual volume snapshots in the object store. These claims highlight the technical implementation of the method in a container system, emphasizing efficient and systematic deletion of volume snapshots.
