user area, and the file can be quite large if the user area contains image files. This is the default for the backup
command.
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.
The backup command stores the MAC address of the switch in the archive. By default, the restore command works
only if the MAC address in the archive matches the MAC address of the switch where the restore command is entered.
The force option overrides this restriction and allows you to unpack one switch’s archive onto another switch.
Note. If the archive’s files cannot fit on the switch, the restore operation fails.
Nortel recommends deleting unneeded image files before creating or restoring an
archive.
Caution! Do not use the force option unless advised to do so by Nortel TAC. If you
restore one switch’s system files onto another switch, you must generate new key pairs
and certificates on the switch.
