Thank you for reaching out regarding the backup and restore issue with your QuickBooks Online (QBO) account, NossaFamiliaCoffee. We understand the critical nature of reliable data management, especially when handling large volumes of information. We appreciate the detailed timeline and description of your interactions with QBO Support. Let me address your concerns and clarify the situation.

When you create a backup in QBO, you save a snapshot of your company data at a specific moment. Unlike traditional backup systems that overwrite existing data, QBO's backup feature safeguards against data loss rather than a full snapshot restoration.

The primary purpose of restoring data from a backup is to recover from mistakes or unintended changes made within QBO. If you accidentally delete or modify information, restoring allows you to revert your account to the state it was at the time of the backup.

We understand this may not align with your expectations of a typical backup and restore process. Please note QBO's restore function doesn't delete or overwrite specific data, such as products or accounts created after the backup. This is particularly relevant when dealing with items like products and accounts, which will not revert to their previous state if added after the backup was created.

In the meantime, you can consider renaming or deactivating the incorrect accounts or items you've imported.

Additionally, you can create a copy of an existing QuickBooks Online Advanced company to use as a new one rather than relying solely on a backup.
