Making backup

STEP 1: If you are not already logged in, connect via SSH or console:

STEP 2: save configuration

admin@sonic:~$ sonic-cli
sonic# write memory

STEP 3: Copy your startup configuration with way You prefer

 sonic# copy startup-configuration
  config:                Copy to configuration directory (config://filename)
  ftp:                   Copy to remote FTP server (ftp://userid:passwd@hostip/filepath)
  home:                  Copy to home directory (home://filename)
  http:                  Copy to remote HTTP server (http://hostip/filepath)

  scp:                   Copy to remote SCP server (scp://userid:passwd@hostip/filepath)

sonic# copy startup-configuration scp://user@1.1.1.1/your/destination/path/backup_config.json

Restore backup

STEP 1: transfer your backup to device via SCP:

scp user@remote-server:</your/destination/path/My_backup.json> <your/destination/path>

STEP 2: Copy backup to config_db.json file

sudo cp <your/destination/path/My_backup.json> /etc/sonic/config_db.json

STEP 3: Reload the Configuration Without Restarting (Optional)

If you want to apply the new configuration without restarting the system:

sudo config reload -y

The system will load the configuration from config_db.json and apply the changes.

STEP 4: Restart SONiC (If Required)

To ensure that all changes take effect properly, restart the system:

sudo reboot

By following these steps, you can successfully restore your SONiC system from a backup configuration.
