How to back up config files on a CISCO device?
Backing Up Config Files on a CISCO Device
Cisco devices, such as routers and switches, store their configuration files in volatile memory (RAM). This means that any changes made to the configuration will be lost if the device loses power or is restarted. To prevent the loss of configuration settings, it is crucial to back up the configuration files to non-volatile memory (NVRAM) regularly.
One way to back up the configuration files on a CISCO device is by using the copy running-config startup-config command. This command copies the running configuration file in RAM to the startup configuration in NVRAM, ensuring that the changes are saved even if the device is powered off or restarted.
The shortest, abbreviated version of the copy running-config startup-config command is simply cop r s. This shorthand notation can save time when entering commands on the CISCO device command line interface.
By regularly backing up configuration files on CISCO devices, network administrators can ensure that the device settings are saved and can be easily restored in case of power loss or device failure.
