Table: NetBackup Snapshot Manager operations on the NetApp E-series array
Snapshot Manager for Data Center operations | Description |
|---|---|
Discover assets | NetBackup Snapshot Manager discovers all the NetApp E-Series volumes and the snapshots. |
Create snapshot | To create a snapshot, NetBackup Snapshot Manager for Data Center initiates a Post Rest API method with the required information. Then, the API returns the details of the snapshot. NetBackup Snapshot Manager for Data Center creates a snapshot with the following description: :vrtscp: <Parent Volume Name> The suffix in the descriptions helps NetBackup Snapshot Manager for Data Center to perform delete operation. 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 rejects any new writes to the base volume. NetApp E-series volume has limitation of 32 snapshots per volume, post which a create snapshot operation results in an error. |
Export snapshot | NetBackup Snapshot Manager exports a snapshot over the iSCSI and FC protocols. When a snapshot export operation initiates, a new snapshot volume is created using a snapshot. The snapshot volume has the following naming convention: SV_snap_seq_no<snapshot sequence no> Once the snapshot volume is created then a host is attached to the same. The SAN zoning must be done between the host and array which is required to attach with the snapshot. Note: The discovery of a snapshot volume that is created in the export operation is skipped. |
Deport snapshot | When a snapshot deport operation is initiated, NetBackup Snapshot Manager for Data Center deletes the export mapping which is created between the host and the snapshot volume. Then, it deletes the intermediate snapshot volume once it is detached from the host. |
Delete snapshot | To delete a Snapshot, NetBackup Snapshot Manager for Data Center initiates a Delete Rest API method call with the required snapshot details. NetBackup Snapshot Manager for Data Center verifies if the suffix (:vrtscp:) is present, then only a snapshot is allowed to delete. For NetApp E-Series, only an oldest snapshot can be deleted at any point of time. If a snapshot is required to delete, then all snapshots that are created before the chosen snapshot must be deleted first. |
Restore snapshot | To restore a snapshot, NetBackup Snapshot Manager for Data Center initiates a Post Rest API method call with the required snapshot details. |
