We need to have a copy of our online back up file . it is possible to get a back up file which could be imported to Quick book desktop

Thanks for posting here, account16.

I understand that you need to back your data up. Though we're unable to do this in QuickBooks Online, you can export your data to an Excel file. Here are the articles for more details:

• Export reports, lists, and other data from QuickBooks Online
• Export your reports to Excel from QuickBooks Online

For now, converting the data is only available in QuickBooks Online US, UK, and CA versions. For the International version, you'll want to look for a third-party that can perform this task. Check this link for your reference: Export and convert your QuickBooks Online data to QuickBooks Desktop.

Keep on posting here if you have more questions. Wishing you all the best!

You may utilize a migration tool. i.e TPExporter for Online, TPImporter for Desktop
