Index Based Deduplication File System in Cloud Storage System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
In a virtualized cloud environment each instance of a guest operating system runs on a virtual machine, contact virtual hard disks symbolized as virtual disk image files in the host operating system. Because these image files are stored as regular files from the external point of view, backing up VM’s data is mainly done by taking snapshots of virtual disk images. In a virtualized cloud computing surroundings, common snapshot support of virtual disks improves hosting reliability but storage demand of such operations is huge. While dirty bit based technique can identify unmodified data among versions; full deduplication with fingerprint assessment can remove more redundant content at the cost of computing resources. So in this project we proposed a LIQUID framework to implement the deduplication scheme in both file and block level. And propose a deduplication file system with low storage consumption and high-performance IO, which satisfies the requirements of VM hosting. Finally we extend our work to address the problem of authorized data deduplication.
