Thank you for your post.
According to your description, two type of applications need to access the folder.
One is database server, it need to write backup files to the folder.
The other is asp.net application, it need to read data from the folder.
Please check whether the two type of applications are run in a single user environment.
If not, you could grant different permissions to each application.
The asp.net application need Read/List-folder-contents permissions.
Hoping my reply could be helpful to you.
