Syntax backup system [tftp:/ip-addr/]filename[all critical]

[tftp:/ip-addr/]filename	Name of the archive file to create. You can store the file
	locally in the switch’s nonvolatile storage or on a TFTP
	server.
all	Backs up system files and all the files in the user files area.
	The user files area contains the set of files listed in the file
	section of dir command output.
critical	Backs up system files only, including the configuration
	file used when booting, and certificate files. The size of an
	archive created by this option is generally 1MB or less.
Defaults The default is all.
Access Enabled.

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 communi- cate with the switch. Use the all option if you also want to back up or restore Web-based AAA pages, backup configuration files, image files, and any other files stored in the user files area of nonvolatile storage.

The maximum supported file size is 32 MB. If the file size of the tarball is too large, delete unnecessary files (such as unneeded copies of system image files) and try again, or use the critical option instead of the all option.

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.

Examples The following command creates an archive of the system-critical files and copies the archive directly to a TFTP server. The filename in this example includes a TFTP server IP address, so the archive is not stored locally on the switch.

WSS# backup system tftp:/10.10.20.9/sysa_bak critical
