Nonstop Backup locks a file needed by our software

Hello,

We are software development company and we have found that Nonstop Backup feature of Acronis True Image Home 2010 prevents our application from working correctly. When our application is started, it creates a file in the 'C:\ProgramData\COMPANY\PRODUCT\VERSION\' folder. After some actions are performed, this file should be deleted for the correct work of our application. However, it seems that the file is locked by the System process for about 5 minutes. Since our application cannot remove the file, it exits with an error.

Could you please clarify what exactly happening and how we can overcome with?

Thanks in advance,
David
