These file names are reserved and may not be used as user-defined files. When the user copies a local source file into one of these special files and the source file has an attached file description, it also is copied as the file description for the special file. • backup-config - This file refers to the backup configuration file. • running-config - This file refers to the configuration file currently active in the system.
