Cloud storage services such as Dropbox have quickly gained enor-mous popularity in recent years. They offer users with convenient and reliable approaches to store and share data from anywhere, any device at anytime. However, they are still suffering from the “traf-fic overuse problem ” in the presence of frequent, short data up-dates [3]. To address this problem, we are implementing a tunable cloud storage service (named “T-CloudDisk”) for flexible batched synchronization. This paper introduces the characteristics, techni-cal approach, and preliminary timeline of T-CloudDisk.
