How to take backups

With QuickBooks Online (QBO), there's no need to take backups of your company file, @accounts380. This is because the system will automatically do it for you. 

The security of your data is our top priority. QBO has a very reliable system that stores your company file. Automatic backups are performed every night. Whenever you've made any changes in your account, it'll automatically be saved. 

Additionally, I'd also recommend printing all your forms and financial reports to serve as your hard-copies. To do this, you can go to the Reports menu, then select the report you need.

I'm also adding this article for a few different methods in exporting your data for your safekeeping: Export Data out of QuickBooks Online. It also includes the link about exporting reports and lists.
