Abstract
Embodiments for creating transactional consistent snapshot copies of SQL server containers in a Kubernetes system for copy reuse on different clusters to facilitate processing local snapshots for secondary workloads without impacting production quality of service. A copy data management (CDM) tool acts as an orchestrator, while a backup toolkit is deployed in the namespace of the production cluster containers. A container storage interface (CSI) plugin supplies persistent storage to the containers. Before taking a copy, the process posts the toolkit in the container and a quiesce/unquiesce operation is then performed. The databases are first quiesced, the snapshot copy is taken, and then the databases are unquiesced. The toolkit is then removed, thus producing a transactional consistent backup in a different namespace.
