Indicates whether incremental backups or replications will use a changed object list to direct the search for changed files; otherwise, it will have to search the entire directory tree looking for changed files. When using the changed object list, the search only passes through those directories that contain changed files.

Where a relatively small proportion of the file system includes directories containing changed files, the use of changed object lists may significantly reduce incremental backup and replication time; however, processing of the changed object list itself may take considerable time. Therefore, where file changes exist in many directories, its use is not recommended.

The default setting for this option can be set using the CLI ndmp-option change_list_incr command.
