How do I backup my accounts to my computer

Hi irishill, thanks for posting on the Community 

It isn't possible to download QBO to your computer as a single file, however, there are a few ways to get your data out of QuickBooks. Many forms, lists, and reports have a download button. You can save copies of these onto your computer's hard drive. 

• You can export multiple reports and lists (like customers and suppliers) into individual Excel files contained in a single zip file in one step.
• If you are looking for a continuous backup of your data, there are apps in the QuickBooks App store that provide this (such as the Rewind Backups app).

We also have measures in place to automatically back up your data with the same level of security used by banks and financial institutions. This means you don't need to worry about saving your QuickBooks data on a flash drive. You can see more on this here. 

Thanks for reaching Intuit support today. We'll be here if you need any further assistance.
