Backup Groups for NAS NDMP clients

As with other clients, NDMP backup groups can consist of full, differential, and incremental backups. The system creates a group when you run a new full backup. Each subsequent differential and incremental backup forms a link in the chain of backups that constitute the group associated with the full backup. Because NDMP backups are run separately for each volume, each volume has its own backup groups. For more information, see Backup groups.
