Backing up your Mikrotik router's configuration is important in case you need to restore settings or in case of a software failure. There are a few ways to backup your Mikrotik router:

1. Export the configuration file:

- Log into your Mikrotik router's web interface

- Go to Files -> Backup 

- Click "Export Configuration"

- Save the configuration file (backup.rsc) to your computer

- This file can be imported again later to restore your configuration

2. Backup to a connected USB drive:

- Connect a USB drive to your Mikrotik router 

- Log into your router's web interface

- Go to Files -> Backup 

- Click "Backup to USB"

- Choose the USB drive and click OK

- A backup file (backup.backup) will be saved to the USB drive

- You can restore the backup later by clicking "Restore from USB"

3. Schedule automatic backups:

- Log into your Mikrotik router's web interface

- Go to System -> Scheduler 

- Click "Add New Task"

- Give the task a name like "Backup to USB"

- For "On Event" select "Time" and enter a schedule (e.g. once a week) 

- For "Action" select "Backup to USB drive"

- Choose your USB drive and click OK

- Click Apply to save the task

- Your router configuration will now be automatically backed up to the USB drive according to the schedule 

4. Backup over Winbox:

- Install Winbox, Mikrotik's Windows utility

- Connect to your Mikrotik router using Winbox 

- Go to Files -> Backup 

- Choose "Export to File" or "Backup to USB" as in options 1 and 2 above

- Save the backup file to your PC or USB drive

5. Use a backup script:

- You can create a backup script to automatically backup your router and save the file to an FTP server or SCP server

- The script would use the /export compact command to export the configuration 

- Schedule the script to run automatically using the scheduler
