Discover assets

Snapshot Manager for Data Center discovers all the managed directories and its associated NFS and SMB directory exports for protection, along with their managed directory snapshots.

Snapshot Manager for Data Center also discovers all the nested managed directories, along with the associated NFS and SMB directory exports. NetBackup discovers assets to the maximum depth to which the managed directories are created on the Pure Storage Flash array cluster.

The managed directories must have an NFS or SMB directory export created, so that Snapshot Manager for Data Center can discover them for protection.

Examples of nested shares discovered by Snapshot Manager for Data Center:

["/test_manage_dir1", "/test_1/test_manage_dir2", "/test_manage_dir1/test_data/test_manage_dir3", "/smb_03/test_data/dir01"]

Create snapshot

To create a managed directory snapshot, Snapshot Manager for Data Center runs a POST REST API call on the array with the required information and the snapshot name.

The API returns the details of the managed directory snapshot. A typical snapshot created by Snapshot Manager for Data Center has the following naming convention:

NB.NB<unique_21digit_number>

Delete snapshot

To delete a managed directory snapshot, Snapshot Manager for Data Center runs a PATCH and DELETE REST API call with the required managed directory snapshot details.

The PATCH REST API updates the directory snapshot with "destroyed": True, and then performs a DELETE REST API process on the managed directory snapshot.

Restore snapshot

Point-in-time restore is not supported by the Pure Storage Flash Array Files Services (NAS). So, NetBackup cannot perform any PIT restore operation.

Export snapshot

When a managed directory snapshot export operation is run:

To make changes in the NFS or SMB export directory and perform backup from snapshot, required access permissions must be set for the backup host. If the backup host is already added to the NFS or SMB directory export policies, then the policy modifications are not required.

Deport snapshot

When a managed directory snapshot deport operation is run, Snapshot Manager for Data Center does not remove the host client rule from the NFS or SMB Policy. The host client rule is added to provide access over the snapshot path at the time of Export. This action prevents disruption to any ongoing backup from snapshot operations associated with the directory export associated with the policy.
