Snapshot operations are not supported for nested shares on Nutanix Files File Server. A nested share is a share that is itself a subdirectory in an existing file share. NetBackup does not support snapshot creation for such nested shares.

Nutanix Files File Server does not support point-in-time (PIT) rollback restore of shares using snapshots. You can use NetBackup assisted restore of shares' data.

The maximum snapshot limit for a Nutanix Files share is 20. The maximum snapshot limit defines the maximum number of policy-initiated snapshots that are retained for the specified share. When the maximum count is reached, the oldest snapshot is deleted, when the policy creates the next snapshot. You may want to consider the policy schedule and retention for NetBackup's policy protecting Nutanix File shares.

Nested shares do not have Changed File Tracking (CFT) based backup support.

Snapshot operations on nested shares are disabled.

The same file server must not be configured on two separate NSM instances. If such a configuration is done, then there are chances of image import and cleanup failing.
