This step is important, since **if the switch reboots, it will reset to this saved config**, rather than any config you have without saving. This is important, because if you lock yourself out of the switch, it resets when you reboot it, so that you don't need to get to the console and reset the switch entirely and loose ALL of the configuration.
## Notes on Backups
The best thing to do is NOT screw up the configuration or do a reset. The switch hardly stores any information about how it was configured in the "backup" file, so if you have a reboot, and you didn't save the config to the switch (as above), it can't be restored. Everything besides the root password will be forgotten. The "backup" and "restore" configuration is seriously lacking in any features (and puts out what looks to be an extremely minimal Cisco-style interface listing and config)
