Thanks for coming in, smmcdonagh.
QuickBooks Online (QBO) is designed to automatically backup your company file. The information will stay unless you manually delete it. However, archiving files from previous years is currently unavailable.
It would be nice to have this feature in QBO. Our developers are always on the look out for new ideas for product enhancements and I'd be happy to share this with them.
In the meantime, you'll want to visit our QuickBooks Blog to be updated with the latest improvements made in QBO.
You can always get back to me if you have other questions. I'd be more than happy to answer them for you. Have a good one.
