Data compression and deduplication are two common approaches to increasing storage efficiency in the cloud environment. Both users and cloud service providers have economic incentives to compress their data before storing it in the cloud. However, our analysis indicates that compressed packages of different data and differently compressed packages of the same data are usually fundamentally diff...

For backup storage, increasing compression allows users to protect more data without increasing their costs or storage footprint. Though removing duplicate regions (deduplication) and traditional compression have become widespread, further compression is attainable. We demonstrate how to efficiently add delta compression to deduplicated storage to compress similar (nonduplicate) regions. A chal...

Modern datacenters assemble a very large number of disk drives under a single roof. Even if economic and technical factors where to make individual drives more reliable (which is not at all clear, given the commoditization of the technology), their sheer numbers combined with their ever increasing utilization in a well-balanced design makes achieving storage reliability a major challenge. In th...

Distributed ledger platforms based on blockchains provide a fully distributed form of data storage which can guarantee data integrity. Certain use cases, such as medical applications, can benefit from guarantees that the results of arbitrary queries against a Linked Data set faithfully represent its contents as originally published, without tampering or data corruption. We describe potential ap...

We propose a new method of ensuring the redundant storage of information on tertiary storage, especially tape storage. Conventional methods for redundant data storage on tape include mirroring (storing the data twice) and Redundant Arrays of Inexpensive Tapes (RAIT). Mirroring incurs high storage costs, while RAIT is inflexible because special hardware is used and all tapes in a stripe must be ...

During the coming years, digital data storage technologies will continue an aggressive growth to satisfy the user's need for higher storage capacities, higher data transfer rates and long-term archival media properties. Digital optical tape is a promising technology to satisfy these user's needs. As any emerging data storage technology, the industry faces many technological and standardization ...

Bioprinting is a method to fabricate 3D models that mimic tissue. Future fields of application might be in pharmaceutical or medical context. As the number applicants vary between only one patient manufacturing tissue for high-throughput drug screening, designing process will necessitate high degree flexibility, robustness, as well comprehensive monitoring. To enable quality by design optimisat...

Abstract: A Data Grid connects a collection of geographically distributed computational and storage resources that enables users to share data and other resources. Data replication, a technique much discussed by Data Grid researchers in recent years creates multiple copies of file and places them in various locations to shorten file access times. In this paper, a dynamic data replication strate...
