showing corrupted text when data backup

I'm here to help fix corrupted data backup in QuickBooks, @kobutacus.

We can utilize the Verify and Rebuild Data tool to self-identifies and resolve the most commonly known data issues within a company file.

Let me show you how:

1. Proceed to the File menu.
2. Choose Utilities and select Rebuild Data.
3. On the QuickBooks Information window, click OK. Follow the onscreen steps to save a backup.
4. Let the tool repair your file. 
5. When the tool finishes, choose OK.
6. Go to the File menu. Then hover over Utilities and select Verify Data.
7. Let the tool check your file for data issues.

If QuickBooks doesn't find any problems, select OK. You can keep using your company file. If QuickBooks finds an issue with your company file, select Rebuild Now.
