Which command creates a full backup of the RouterOS configuration?

• A. /system backup save
• B. /system export
• C. /system reset
• D. /system scheduler add

Answer: (A)

Saving a full backup captures everything in RouterOS’s configuration into one binary file that can be loaded back to restore the device. The command to create that binary backup is /system backup save. This produces a backup file you can later restore with /system backup load to quickly return the router to its previous state.

In contrast, /system export prints the configuration as a readable script you could use to recreate settings, but it isn’t the same as a complete binary backup and may not carry all state or secrets in a readily restorable form. The other options perform actions unrelated to backing up: resetting the device to factory defaults, or adding a scheduled task.
