Table: Snapshot Manager for Data Center operations on Fujitsu AB/HB array
Snapshot Manager for Data Center operations | Description |
|---|---|
Discover snapshot | NetBackup Snapshot Manager for Data Center discovers all the Fujitsu AB/HB volumes and their snapshots. |
Create assets | For each volume, NetBackup creates a snapshot group with the following naming convention: NBSG<volume_name> The snapshot group is created with 40% capacity of the base volume. All snapshots on that volume are created inside this Snapshot Group. When the reserved capacity for a snapshot group is full, it will reject any new writes to the base volume. Fujitsu AB/HB Volume has a limitation of 32 snapshots per volume, post which the create snapshot operation results in an error. To create a snapshot, NetBackup Snapshot Manager for Data Center triggers a Post Rest API method with the required information. The API returns the details of the snapshot. Snapshots created by NetBackup Snapshot Manager for Data Center have the description: :vrtscp: <Parent Volume Name>. Using this suffix in the description, NetBackup Snapshot Manager for Data Center decides that this Snapshot has been created by NetBackup. It is then allowed to delete the same. |
Export snapshot | NetBackup Snapshot Manager for Data Center supports export snapshots over the iSCSI and FC protocols. When a snapshot export operation is triggered, a new Snapshot Volume is created using the Snapshot. The Snapshot Volume has the following naming convention: SV_snap_seq_no<snapshot sequence no> Once this SV is created, then a host is attached to the same. The SAN zoning should be done between the host and the array that is required to be attached to the snapshot. Note: The discovery for the Snapshot Volume created in the export operation will be skipped. |
Delete snapshot | To delete a Snapshot, NetBackup Snapshot Manager for Data Center triggers a Delete Rest API method call with the required snapshot details. NetBackup Snapshot Manager for Data Center checks for suffix (:vrtscp:) only when this suffix is there, Snapshot will be allowed for deletion. For Fujitsu AB/HB, only the oldest snapshot can be deleted any time. If any delete operation other than this is triggered, it results in an error. If a snapshot must be deleted, then all snapshots taken before that snapshot must be deleted. |
Restore snapshot | To restore a Snapshot, NetBackup Snapshot Manager for Data Center triggers a Post Rest API method call with the required snapshot details. |
Deport snapshot | When a snapshot deport operation is triggered, NetBackup Snapshot Manager for Data Center deletes the export mapping created between the host and the Snapshot volume, and it deletes the intermediate Snapshot Volume once it is detached from the host. |
