486CHAPTER 18: FILE MANAGEMENT COMMANDS

restore	Unzips a system archive created by the backup command and copies the
	files from the archive onto the switch.
	Syntax restore system [tftp:/ip-addr/]filename [all
	critical]
	Defaults — Critical.
	Access — Enabled.
	History —
	Usage — If a file in the archive has a counterpart on the switch, the archive
	version of the file replaces the file on the switch. The restore command does
	not delete files that do not have counterparts in the archive. For example, the
	command does not completely replace the user files area. Instead, files in the
	archive are added to the user files area. A file in the user area is replaced only
	if the archive contains a file with the same name.
	Note: If the archive’s files cannot fit on the switch, the restore operation
	fails. 3Com recommends deleting unneeded image files before creating
	or restoring an archive.
	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.
	CAUTION: Do not use the force option unless you are certain you want
	to replace the switch’s files with files from another switch. If you restore
	one switch’s system files onto another switch, you must generate new
	key pairs and certificates on the switch.
	Examples — The following command restores system-critical files on a
	switch, from archive sysa_bak.
	WX1200# restore system tftp:/10.10.20.9/sysa_bak
	success: received 11908 bytes in 0.150 seconds [ 79386
	bytes/sec]
	success: restore complete.
