NetBackup Snapshot Manager for Data Center performs the following snapshot management operations on the HPE GreenLake for the block storage array:
Table: NetBackup Snapshot Manager for Data Center operations on the HPE GreenLake for Block Storage array
Snapshot Manager for Data Center operations | Description |
|---|---|
Discover assets | NetBackup Snapshot Manager for Data Center discovers GreenLake storage volumes (except clone volumes and system volumes) and snapshots. Volumes are primary assets, each contains the associated snapshots and asset IDs. NetBackup Snapshot Manager for Data Center also discovers the replication configuration of volumes and snapshots, including the target array, remote copy group, replication mode, and other related settings. |
Create snapshot | NetBackup Snapshot Manager for Data Center takes a snapshot of HPE volume. To create a snapshot, NetBackup Snapshot Manager for Data Center initiates a POST API call on the volume. A typical snapshot created has the following naming convention: NB<unique_21digit_number> |
Delete snapshot | NetBackup Snapshot Manager for Data Center can delete snapshots. When you delete a snapshot, NetBackup Snapshot Manager for Data Center deletes the snapshot corresponding to the source volume. |
Replicate snapshot | Only SYNC-based replication is supported. If replication is configured in the NetBackup SLP, a coordinated snapshot is taken. This is a simultaneous snapshot of both the source and target volumes on the source and target arrays. This coordinated snapshot is a read-only snapshot. As a step in the replication process, NetBackup retrieves the snapshot from the target array, for further processing. |
Restore snapshot | NetBackup Snapshot Manager for Data Center restores the parent volume, when you restore a volume from a volume snapshot. When a snapshot restore operation is initiated, NetBackup Snapshot Manager for Data Center unmaps the source volume and snapshot volume from all the host and host sets. A snapshot volume cannot be restored when it is exported to a host or host set and if the parent volume is exported to hosts or host sets. After completion of the restore operation, NetBackup Snapshot Manager for Data Center again maps the parent volume and the snapshot volume to all the host and host sets. PIT rollback restore is not supported if the volume has replication configured for it. You cannot rollback volumes that are configured for replication. |
Export snapshot | When a snapshot export operation is initiated, NetBackup Snapshot Manager for Data Center attaches a snapshot of the volume to the host. NetBackup Snapshot Manager for Data Center fetches the initiators where you want to perform the export operations based on the port. The initiator retrieves the host ID, and then NetBackup Snapshot Manager for Data Center attaches the snapshot volume to the host. |
Deport snapshot | When a snapshot deport operation is initiated, NetBackup Snapshot Manager for Data Center removes the host mapping of the exported snapshot volume. It is a revert of the export snapshot operation. |
