It’s great to see you in the Intuit Community, F1.

Let’s sort out why you’re seeing new backup files when entering transactions in QuickBooks.

Ideally, QuickBooks Desktop does not automatically create backup files when entering data. Backups are saved to your preferred location once you opt to manually create one or if you've signed up for automatic backups.

The automatic backups save a copy of the company after a set number of times you close the file. This feature will directly save the data entered in the company to avoid accidental loss. 

For more insights, check out the Create backup of the QuickBooks Desktop company file article. Then, proceed to the If you choose Save it now and schedule future backup or Only schedule future backups section.

If this isn’t what’s happening, I appreciate if you could provide more details to help me get on the same page.

Thanks in advance. I’ll be on the look out for your response.
