This paper presents an analytical hardware model for tertiary-storage jukeboxes. A jukebox can store large amounts of data in a cost-effective way, which makes it eminently suitable for applications that handle large amounts of continuous-media files, large databases and backups. However, to use a jukebox effectively it is important to schedule the jukebox resources. In order to build accurate ...

Preserving digital information over the long term becomes increasing important for large number of institutions. The required expertise and limited tool support discourage especially small institutions from operating archives with digital preservation capabilities. Hoppla is an archiving solution that combines back-up and fully automated migration services for data collections in environments w...

Many cooperated web cache systems and protocols have been proposed. But, these systems need the expensive resources, such as core-link bandwidth and proxy cpu or storage, and need administrative cost to achive enough performance when the client population increases. This paper suggests a self-organizable caching system, called Subway, which is scalable and fault tolerant, with a distributed pee...

I.INTRODUCTION In this paper with the potentially unlimited storage space offered by cloud providers, users tend to use a large amount space as they can and vendors continually look for techniques aimed to reduce redundant data and exploit space savings. A technique which has been widely adopted is crossuser deduplication. The simple idea behind deduplication is to accumulate duplicate data onl...

Scalable, highly reliable distributed systems supporting data deduplication have recently become popular for storing backup and archival data. One of the important requirements for backup storage is the ability to delete data selectively. Unlike in traditional storage systems, data deletion in distributed systems with deduplication is a major challenge because deduplication leads to multiple ow...

This paper presents a micro-payment-based incentive mechanism for long-term peer-to-peer storage systems. The main novelty of the proposed incentive mechanism is to allow users to be off-line for extended periods of time without updating or renewing their information by themselves. This feature is enabled through a digital cheque, issued by the user, which is later employed by the peers to get ...

Many people now store large quantities of personal and corporate data on laptops or home computers. These often have poor or intermittent connectivity, and are vulnerable to theft or hardware failure. Conventional backup solutions are not well suited to this environment, and backup regimes are frequently inadequate. This paper describes an algorithm which takes advantage of the data which is co...

Archival storage systems must operate under stringent requirements, providing 100% availability while guaranteeing that data will not be lost. In this paper we explore the multiple interconnected subsystems that must be tuned to simultaneously provide high data transfer rates, high transaction rates, and guaranteed meta-data backup. We examine how resources must be allocated to the subsystems t...

“Cloud computing” gradually flourish, a wide range of distributed storage systems are increasingly diverse, Like of Gluster, Ceph, Lustre, as well as Hadoop, etc.. In this paper, we propose a personal cloud storage system Integrated with pNFS, it can be accessed in parallel for scalable performance. Besides, data backup and failover mechanism are designed. We expect that the function of the pro...
