What is the file extension used for RouterOS backups?

• A. .txt
• B. .config
• C. .backup
• D. .rsc

Answer: (C)

RouterOS backups are binary snapshots of the entire device state, including configurations and system settings, saved with the .backup extension. This format is meant for restoring the exact setup later, not for editing. In contrast, a configuration export is saved as a text script with the .rsc extension, which you can read or modify before applying. The other extensions listed aren’t used for RouterOS backups. To create one, use /system backup save name=backup, and to restore, use /system backup load file=backup.backup (or perform the restore via the GUI).
