Copying Files
The copy command not only provides a method for copying files within the
file system, but also to and from remote servers. With the copy command and
URLs to identify files, the user can back up images to local or remote systems
or restore images from local or remote systems.
To use the copy command, the user specifies the source file and the
destination file. For example, copy
config
copies a file from the remote TFTP server to a local backup
configuration file. In this case, if the local configuration file does not exist,
then it is created by the command. If it does exist, it is overwritten. If there is
not enough space on the local file system to accommodate the file, an error is
flagged.
Refer to the copy
commands section of the guide for command details.
Referencing External/Internal File systems
Configuration or software images are copied to or retrieved from remote file
systems using the TFTP protocol.
• tftp://server-name/path/filename — identifies a file on a remote file system
accessible through the server-name. Trivial file transfer protocol is a
simplified FTP and uses a UDP port instead of TCP and does not have
password protection.
Special System Files
The following special filenames are used to refer to special virtual system files,
which are under control of the system and may not be removed or added.
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. It is possible to copy the running-config image to a backup-
config file or to the startup-config file.
