Data deduplication has been broadly used in the Cloud due to its storage space saving ability. One issue with deduplication is a phenomenon called data fragmentation. To deal with data fragmentation, Cloud implements a procedure that diminishes the restore performance. Although capping methods have been developed to alleviate data fragmentation, they employ rewriting procedures that are only partially successful. To address this problem, TSYS School assistant professor of computer science Yi Zhou and his research colleagues from Jinan University (China) and the University of Exeter (United Kingdom) propose a multi-segment greedy rewriting method named MGRM. As they explain in their study forthcoming in IEEE Transactions on Cloud Computing, MGRM works sequentially to rewrite in a way that achieves a good balance between deduplication and restore performance. To do so, it adaptively switches between two working modes – an optimal rewriting mode and a radical rewriting mode – according to workload. The optimal rewriting mode utilized by MGRM improves deduplication, while the radical rewriting mode is utilized to improve restore performance. Thus, unlike existing capping methods that improve restore performance at the cost of deduplication, MGRM pays attention to both aspects. Extensive experimental results presented in the study show that MGRM achieves high restore performance, coupled with high deduplication. In particular, compared to two state-of-art schemes, MGRM improves deduplication and restore performance by up to 114.83% and 99.34%, respectively.
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
