New Research by Zhou Improves Data Deduplication in Backup Storage Systems

As TSYS School computer science professor Yi Zhou and his colleagues from Jinan University and the University of Maine explain in their new study, data deduplication has been widely used in backup storage systems to improve storage utilization and extend device lifetime by reducing data writes. Inline deduplication, in particular, removes redundant data in real-time as data is being sent to the storage system. However, it causes data fragmentation, meaning that logically consecutive chunks are physically scattered across various containers after data deduplication. Many existing rewrite algorithms aim to alleviate the performance degradation due to fragmentation by rewriting fragmented duplicate chunks as unique chunks into new containers. Unfortunately, these algorithms determine whether a chunk is fragmented based on a simple pre-set fixed value, ignoring the variance of data characteristics between data segments. This means that when backups are restored, they often fail to select an appropriate set of old containers for rewrite, generating a substantial number of invalid chunks in retrieved containers. To address this issue, Zhou and his colleagues propose an inline deduplication approach for storage systems, called InDe, which detects valid container utilization and dynamically adjusts the number of old container references in each segment. InDe is designed to improve restore performance while maintaining high backup performance by identifying appropriate containers for the rewrite. Lastly, Zhou and his colleagues are able to evaluate InDe using three real-world backup workloads. The experimental results presented in the study, which appears in the current issue of ACM Transactions on Storage, show that compared to two other state-of-the-art algorithms, InDe improves restore speed by 1.3 to 2.4 times while also achieving similar backup performance.

Grant Hits Ground Running as New Turner College Marketing Intern

The Turner College's new marketing intern Lizzy Grant , a senior marketing major from Newnan who previously attended Gordon State College, where she played varsity soccer, and is scheduled to graduate from the Turner College in May of 2024, has hit the ground running in her new position. She recently played a large role in the creation of a video tour of the Synovus Center, the main campus home of the Turner College. The video helps to guide new students on where to go in the building and who they can talk to if they help. The video showcases the Student Services Center, the main lobby, and more. The video is played as part of a loop on video screens placed throughout the Synovus Center. Lizzy's list of activities at CSU is impressive. She is the Treasurer of the Turner College's Marketing Club, the President of Marketing for the Turner College's chapter of the Financial Management Association, and an Ambassador for the Turner College. She is also the Treasurer of her s

Jung Exploring Influence of Confucianism on Luxury Brand Performance in China, Japan and South Korea

In a recent chat with Turner Business , Turner College professor of marketing Sungwoo Jung made the point that luxury brands are gaining the degree of influence in many developing countries that they enjoy now in developed countries. He has been pondering this issue as part of his international marketing research program, which typically focuses on advertising, pioneering advantages and multi-cultural analysis. Currently, Jung is concentrating his energies on a cross-cultural analysis of brand equity that highlights luxury brands’ performance. His research finds that China, Japan and South Korea have each seen an increase in market share for luxury brands in recent years. As Jung explained to Turner Business , “These three countries share a common philosophical background – Confucianism.” With that point in mind, Jung and his coauthors are currently engaged in an investigation of how Confucianism influences consumer behavior in these three Asian countries, and how that behavior im

Turner College Grad Publishes Academic Study on Corporate Culture and Strategy

Former Turner College student Tamara Todorova , now an associate professor of economics at American University in Bulgaria (AUB), recently published a study on corporate culture and strategy. Todorova earned an MBA from the Turner College in 1996 and then went on to earn a doctorate in international economics from the University of Economics - Varna in 2001. She has been on the faculty at AUB since August of 2000. Todorova's study, which appears in the current issue of the International Journal of Business Performance Management , investigates how corporate culture helps to economize on the transaction costs of internal organization. As she explains, the dimensions of corporate culture that assist in this task include increasing trust and reducing intrafirm opportunism. Todorova's study demonstrates that setting common goals and a common direction reduces the sizeable costs of internal organization. Tamara's prior research appears in Economics of Transition , International
