“…Because the active archive system restores files to main storage when accessing a link (or an online mode file), there is a recovery delay for all archived file accesses. Amazon S3 Intelligent-Tiering [25] organizes storage with three or four layers and moves old files from higher layer to lower layer storage. When a file in the lower layer storage is accessed, it moves to the top layer (Frequent Access Tier) storage.…”

“…Some commercial cloud file synchronization services [8][9][10][11] provide the functionality to change the online and local modes of files, but this function only allows users to manually change the mode of selected files on an on-demand basis. There are also cloud storage and distributed file systems [12][13][14][15][16][17][18][19][20] and other multi-tiered storage systems [21][22][23][24][25][26][27][28][29][30] that use similar approaches to the proposed file mode transition mechanism by prefetching or caching files among storages. However, as they focus more on the performance of file access in costly high-layered storages, cache hit ratio or prediction accuracy are the most important performance metric.…”

In this paper, we propose an active file mode change mechanism in which the file synchronization system of cloud storage automatically changes files in a directory of a client to the online or local mode by considering tradeoff between local storage usage and file access time according to directory activation ratio. When the directory activation ratio rises above a certain threshold, the proposed active file mode change mechanism selects online mode files in this directory based on file access delay time and local storage usage and changes them to the local mode to reduce file access delay of active IoT clients. When the directory activation ratio falls below the threshold, the active file mode change mechanism selects the local mode files based on the last access time and local storage usage and changes them to the online mode to increase available local storage. Experimental results show that the proposed active file mode change mechanism can control when and how much the client can reduce and increase the local storage usage and the file access delay by changing file mode parameters according to the requirements of various IoT devices.
