470 CHAPTER 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.
