Can I back up my own files to a flash drive?

You can convert your data to QB Desktop file format and use the trial version to access your historical data for good if required.

Let me help you back up your QuickBooks Online (QBO) files to a flash drive, bl.svoboda.

If you're using QBO Simple Start, Essential, or Plus, the option to back up your files is unavailable. However, you can still export your reports and lists to Excel and transfer them to your flash drive. For more details, you can visit this article: Export reports, lists, and other data from QuickBooks Online.

To use the Backup and Restore feature, you can consider upgrading your plan to QBO Advanced. 

Alternatively, you can use a third-party app to back up your files. Here's how to find one:

1. Sign in to your QBO account.
2. Choose the Apps tab on the left navigation bar.
3. Look for the app you want to connect to in the magnifying glass bar or select the Browse category dropdown to search for an app by category.

Moreover, you can follow 4Gal's suggestion.

Here's an article that can guide you through the process of backing up and restoring your files in QBO Advanced: Back up and restore your QuickBooks Online Advanced Company.
