NDMP environment variables overview

NDMP environment variables are associated with paths. When an environment variable path matches with the path of a backup or a recovery operation, the environment variable is applied to that operation.

All the environment variables reside under the /ifs directory. There are two other virtual paths, namely, /BACKUP and /RESTORE that contain environment variables. The environment variables under this path can be applied globally. The environment variables under /BACKUP are applied to all the backup operations. The environment variables under /RESTORE are applied to all the recovery operations. The global environment variables are applied only after the path-specific environment variables are applied. So, the path-specific variables take precedence over the global variables.
