I dont find the backup option in my quickbook tools menu

I'm thrilled to have you here today.

I can see how this feature can help you manage your company data. If you're using QuickBooks Online (QBO), this option isn't available inside the program. The backup file option is only available on QuickBooks Desktop (QBDT) version. However, you can get through this by manually exporting your files outside your company. This way, you can secure a copy of it and then make use of it soon.

Feel free to check this page for more information: Export Data out of QuickBooks Online.

Additionally, I've got you this article to help you manage your company's billing information: Update billing, payment, and subscription info in QuickBooks Online.

In case you need further assistance with handling your company's data. Please don't hesitate to mention me in the comment section below. I've got you covered. Stay safe!

You can use a 3rd party backup restore app
