Examples
RBT-8100# backup system tftp:/10.10.20.9/sysa_bak critical
success: sent 28263 bytes in 0.324 seconds [ 87231 bytes/sec]
Thefollowingcommandrestoressystem‐criticalfilesonaswitch,fromarchivesysa_bak:
RBT-8100# restore system tftp:/10.10.20.9/sysa_bak
success: received 11908 bytes in 0.150 seconds [ 79386 bytes/sec]
success: restore complete.
Note: The next time the switch is restarted after the restore command is used, the switch uses the
boot configuration filename that was in use when the archive was created. If you change the boot
configuration filename after creating the archive, the new name is not used when the switch is
restarted. To use the new configuration, use the save config filename command, where filename is
the name of the boot configuration file restored from the archive, before you restart the switch. If you
have already restarted the switch, use the load config filename command to load the new
configuration, then use the save config filename command.
