Snapshot Manager for Data Center performs the following management operations on the Nutanix Files File Server:

Table: Snapshot Manager for Data Center operations on Nutanix Files File Server

Snapshot Manager for Data Center operation

Description

Discover assets

Snapshot Manager for Data Center discovers all the shares and their snapshots, along with some of their metadata. Shares that have CFT_BACKUP capabilities are eligible for snapshot-diff based incremental backups.

Note:

Snapshot operations are not supported for nested shares on the Nutanix Files File Server.

Create snapshot

To create a snapshot, Snapshot Manager for Data Center initiates a POST REST API call on the /mount_targets API with the required share information and snapshot name. The API returns the details of the snapshot (also referred to as the mount target snapshot). Snapshot Manager for Data Center keeps polling the snapshot details until the snapshot state changes to successful (or error in case of failure).

A typical snapshot created by NetBackup Snapshot Manager for Data Center has the following naming convention: NB<unique_21digit_number>

Delete snapshot

To delete a snapshot, Snapshot Manager for Data Center initiates a DELETE REST API call with the required snapshot details in the following format:

/mount_target_snapshot/:snapshot_uuid

Snapshot Manager for Data Center keeps polling the snapshot UUID until it returns a 404 Not Found error code. This code confirms that the snapshot has been deleted successfully.

Restore snapshot

Snapshot Manager for Data Center does not support this operation.

Export snapshot

When a snapshot export operation is initiated, the backup host is added to the partner server that is registered during the plug-in configuration. A PUT REST API call is made to the partner server with the required mount target details. The Snapshot Manager for Data Center keeps polling the partner server to confirm the success of the operation.

Deport snapshot

When a snapshot deport operation is initiated, Snapshot Manager for Data Center makes a PUT REST API call to the partner server to remove the mount target entry that was added during the export operation. The Snapshot Manager for Data Center keeps polling the partner server to confirm the success of the operation.

Create snapshot diff

Nutanix Files provides an API that allows you to create a diff between two snapshots of a share. This process is called Changed File Tracking (CFT). When a request to create a snapshot diff is made, Snapshot Manager for Data Center makes a REST API call to generate the CFT between two snapshots, and then retrieves and stores the CFT data on the Snapshot Manager for Data Center server. CFT-based backups are supported only for top-level shares. Nested shares are not supported.
