Enhanced Dynamic Whole File De-Duplication (DWFD) for Space Optimization in Private Cloud Storage Backup

Provable Ownership of Encrypted Files in De-duplication Cloud Storage

The rapid adoption of cloud storage services has created an issue that many duplicated copies of files are stored in the remote storage servers, which not only wastes the communication bandwidth for duplicated file uploading, but also increases the cost of security data management. To solve this problem, client-side deduplication was introduced to avoid the client from uploading files already e...

An EMC Perspective on Data De-Duplication for Backup

CLDSafe: An Efficient File Backup System in Cloud Storage against Ransomware

Ransomware becomes more and more threatening nowadays. In this paper, we propose CLDSafe, a novel and efficient file backup system against ransomware. It keeps shadow copies of files and provides secure restoration using cloud storage when a computer is infected by ransomware. After our system measures file similarities between a new file on the client and an old file on the server, the old fil...
