To verify my understanding, are you working with QuickBooks Online (QBO) or QuickBooks Desktop (QBDT)?
If you're using QBDT's Intuit Data Protect (IDP) feature to perform your backups, you can troubleshoot with the steps in our Unable to back up with IDP article.
In the event you're working with QBO, would you be able to provide a screenshot of the message you're seeing when trying to perform a backup?
I've also included a couple detailed resources about working with backups in both products which may come in handy moving forward:
I'll be looking forward to your reply. Have a lovely day!
