Data Deduplication describes approach that reduces the storage capacity needed to store data or the data has to be transfer on the network. Cloud storage has received increasing attention from industry as it offers infinite storage resources that are available on demand. Source Deduplication is useful in cloud backup that saves network bandwidth and reduces network space Deduplication is the pr...

In this paper we introduce the new problem of finding the best way to protect a computer system against cyber and ransomware attacks by choosing an optimal backup scheme using k storage devices. While in standard backup schemes it is beneficial to backup as frequently as possible, in the case of sophisticated cyber attacks any attempt to connect a backup device to an already infected computer i...

Continuous Data Protection (CDP) can restore data to any point-in-time, but high storage overhead and drastic system performance drop restricts its application. In this paper, we propose a file version based file level CDP system (FV-CDP) by using cheap distributed storage for backup to low down the storage costs and using local object cache and parralel asynchronous object sending to mask netw...

As the amount of valuable data that the average person owns increases, there is a growing need for personal low cost backup services. A variety of methods have been developed to fulfill this need, from cloud based backup services to cooperative methods where users share spare resources to store each other’s data, either using a peer-to-peer (P2P) network to store data among a large number of di...

Storage has been extensively studied during the past few decades (Foster et al., 1997; Jos Guimares, 2001). However, the emerging trends on distributed computing bring new solutions for existent problems. Grid computing proposes a distributed approach for data storing. In this paper, we introduce a Grid-based system (ARCO) developed for multimedia storage of large ammounts of data. The system i...

A major hurdle to deploying a distributed storage infrastructure in peer-to-peer systems is storing data reliably using nodes that have little incentive to remain in the system. We argue that a node should choose its neighbors (the nodes with which it shares resources) based on existing social relationships instead of randomly. This approach provides incentives for nodes to cooperate and result...

Furthermore, BLU Acceleration is built directly into the DB2 kernel (see Figure 1). It is not just an additional feature; it is an integral part of DB2 and every part of DB2 is aware of it. BLU Acceleration still uses the same storage unit of pages, the same buffer pools, and the same backup and recovery mechanisms, so BLU Acceleration tables can coexist with traditional row tables in the same ...
