About using the cloud immutable storage in a cluster environment
Earlier, NetBackup supported the deployment of the cloud immutable storage in a single node. From NetBackup 10.1.1, NetBackup supports deployment of the cloud immutable storage in the cluster environments such as Azure Kubernetes Service (AKS), Amazon Elastic Kubernetes Service (EKS), and NetBackup Flex Scale.
See About MSDP cloud immutable (WORM) storage support.
You can back up the data to cloud WORM storage to prevent the data from being deleted or overwritten for a fixed amount of time. Currently, MSDP supports the following cloud immutable storages. You can deploy all these cloud immutable storages in the NetBackup cluster environments.
Amazon S3 Object lock
Amazon S3 compatible storage
See About immutable object support for AWS S3 compatible platforms.
Azure immutable storage
See About immutable storage support for Azure blob storage .
To use the cloud immutable storage, the following two steps are performed:
Use msdpcldutil command tool create the cloud immutable volume.
Use NetBackup WebUI to deploy the storage unit.
When using msdpcldutil command tool to update the cloud WORM volume configuration, it is recommended that you run it in the MSDP storage server engine. Otherwise, MSDP takes time to fetch the updated configurations from cloud. The maximum time is 30 minutes (1800 seconds) which is defined by the option CloudLSUCheckInterval in spa.cfg.
