NDMP file list backup overview

The NDMP file list backup process allows you to perform a backup operation based on a list of files.

An NDMP backup session can either be full or incremental. A full backup session backs up every file under a path. An incremental backup session backs up changed files under the same path of a full backup. For both the backup types, you can specify the files to be backed up by generating a file list. A data management application (DMA) can pass the BACKUP_FILE_LIST environment variable to specify a file path. The file pointed by the file path can have a list of files relative to the backup directory that need to be backed up. The NDMP file list backup operation processes the files in the file list based on the BACKUP_FILE_LIST environment variable setting without traversing through the entire backup directory for backing up the files.

Refer to the sections Managing file list backups, Placement of the file list, and Start a file list backup in this guide for information about how to work with file lists.
