With the advent of cloud computing, huge amount of data are stored on the cloud. To remove the redundant data, the Deduplication technology is proposed and attracts many interests from both the academic and industry. In the Inline Deduplication System, improving the read performance is very vital. However, existing works is inefficient when massive data are involved. In this paper, we first propose...
In a virtualized cloud computing environment, frequent snapshot backup of virtual disks improves hosting reliability but storage demand of such operations is huge. While dirty bit-based technique can identify unmodified data between versions, full deduplication with fingerprint comparison can remove more redundant content at the cost of computing resources. This paper presents a multi-level selective...
