470CHAPTER 18: FILE MANAGEMENT COMMANDS

backup	Creates an archive of WX system files and optionally, user file, in Unix
	tape archive (tar) format.
	Syntax backup system [tftp:/ip-addr/]filename [all
	critical]
	Defaults — All.
	Access — Enabled.
	History —.
	Usage — You can create an archive located on a TFTP server or in the
	switch’s nonvolatile storage. If you specify a TFTP server as part of the
	filename, the archive is copied directly to the TFTP server and not stored
	locally on the switch.
	Use the critical option if you want to back up or restore only the
	system-critical files required to operate and communicate with the
	switch. Use the all option if you also want to back up or restore WebAAA
	pages, backup configuration files, image files, and any other files stored
	in the user files area of nonvolatile storage.
	Neither option archives image files or any other files listed in the Boot
	section of dir command output. The all option archives image files only if
	they are present in the user files area.
	Archive files created by the all option are larger than files created by the
	critical option. The file size depends on the files in the user area, and the
	file can be quite large if the user area contains image files.
	The backup command places the boot configuration file into the archive.
	(The boot configuration file is the Configured boot configuration in the
	show boot command’s output.) If the running configuration contains
	changes that have not been saved, these changes are not in the boot
	configuration file and are not archived. To make sure the archive contains
	the configuration that is currently running on the switch, use the
	save config command to save the running configuration to the boot
	configuration file, before using the backup command.
