Discover assets

NetBackup Snapshot Manager discovers all the Dell EMC PowerStore NAS servers, primary NFS exports, and SMB shares and their filesystem-snapshots along with some of their directory metadata. NetBackup Snapshot Manager also discovers the nested NFS exports and SMB shares irrespective of the depth at which they are created.

Create snapshot

To create a snapshot, NetBackup Snapshot Manager triggers a POST REST API using SDK method with the required information and snapshot name. The API returns the details of the snapshot. Dell EMC PowerStore supports two types of snapshots - protocol and snapshot type. NetBackup Snapshot Manager triggers the protocol type snapshots and retention period is not set on the array for these snapshots. All these snapshots are at a file system level.

A typical snapshot created by Snapshot Manager for Data Center has the following naming convention:

NB<unique_21digit_number>

Delete snapshot

To delete a snapshot, NetBackup Snapshot Manager calls the DELETE REST API using SDK method, with the required snapshot details.

The API confirms that the snapshot has been deleted successfully on the array.

Restore snapshot

NetBackup Snapshot Manager does not support PIT restore operation on the array. Instead we can perform Normal restore on specified location.

Export snapshot

NetBackup Snapshot Manager supports export operation using the NFS and SMB protocol. When a snapshot export operation is triggered based on selected protocol a new NFS export or SMB share is created using snapshot and parent export/share local path. The newly created export/share name is same as snapshot name. Also the host access configurations are added as read-only on a particular export or share.

Deport snapshot

When a snapshot deport operation runs, NetBackup Snapshot Manager deletes the NFS export or SMB share created over the snapshot at the time of the export operations.
