Store backup console output store it in backup.txt

in CKA exam, i am unable to understand question how can i store backup console output in backup.txt?

question:
take backup and store it in /opt/cluster_backup.db file, and also store backup console output store it in backup.txt

Usually the exam will be more specific that “backup console output”. If something needs to be saved to a text file, they will say specifically what that is.

Understood!
thank you rob for your response.
