How to back up data

Hi there, rtek84.

I'd like to share some information about data backup in QuickBooks Online.

In the Online product, there's no need to back up your data since the system will do it automatically. It performs every night, which means every time you make changes to your account, the system also updates your records. With that, it's okay not to save your information on a flash drive. 

Check this article to know more how data in the QuickBooks program gets replaced with the latest data stored online: Do I need to back up my data with QuickBooks Online?.

I hope the information helps you. If you still have more something to ask, don't hesitate to post again. Enjoy your day. Take care!
