While we can now outsource data backup to third-party cloud storage services so as to reduce data management costs, security concerns arise in terms of ensuring the privacy and integrity of outsourced data. We design FADE, a practical, implementable, and readily deployable cloud storage system that focuses on protecting deleted data with policy-based file assured deletion. FADE is built upon st...

Most small and medium-sized enterprises (SME) operate from a single address, which means that backups are normally kept at the same physical location as the company’s computers. This means that fire, flooding or other disasters are likely to destroy both computers and the backups that were meant to ensure the continued operation of the company. The price per Giga-byte of hard disk storage is fa...

In this paper, we mainly focus on a problem to realize highperformance systems without sacrificing system reliability. One solution for high-performance is to use main memory as ‘a database storage. Since main memory cannot be free from software bug or electricity hazard, we cannot avoid archive storages such as disks. To reduce the time of checkpoint and recovery for a main memory database, so...

Deduplication of live storage volumes in a cloud computing environment is better done by post-processing: by delaying discovery and removal of duplicate data after I/O requests have been concluded, impact in latency can be minimized. When compared to traditional deduplication in backup systems, which can be done in-line and in a centralized fashion, distribution and concurrency lead to increase...

With the increasing popularity of open-source platform Hadoop, the meteorological industry is available to create a Meteorological Cloud (MeteCloud) platform to store and deploy applications. In this paper, we propose an idea to build the MeteCloud platform for meteorological departments using Hadoop. We also present a backup policy for meteorological data. In addition, one kind of storage proc...
