The internet plays significant roles in different aspects of daily life especially in education and learning fields. Nowadays, many interactive applications have been emerged to satisfy the requirements of both teachers and students. These applications can contribute to the ease of the data delivery processes which are essentially depending on the internet access. In this paper, new backup technique have been proposed to surpassing the issue of internet outage. The teacher quality assurance system at University of Duhok have been taken as a case study to evaluate the designed technique. The designed technique mainly focuses on overcoming the issue of internet outage while the academic staff get their students’ feedbacks. The proposed technique has been successfully designed to fulfill two main goals: first, the internet outage can recovered by adding a local backup server that can achieve parallel tasks, and this local server replace the main server when the internet connection is unavailable. Second, the backed up information in the local server will be automatically uploaded to the main server once the internet is available. The approached used in this paper minimizes three key aspects in internet-based IMSs, which are traffic, time, and IT requirements.
