Tape backup has traditionally been the mainstay of enterprise data protection when long-term data protection is required. As disk technologies have improved and economies of scale have driven down prices, disk adoption rates have surged and it would appear disk is poised to eclipse tape as the dominant backup platform and relegate tape to a minor archival and disaster recovery role. Numerous su...
An ad hoc wireless network supports data networking without an infrastructure, so that users can use network services while continually moving. Each move of the mobile host affects the topology of the network and the transmission route. The Ad Hoc Backup Node Setup Routing Protocol (ABRP) is proposed to focus attention on the intrinsic properties of the ad hoc wireless networks. Basically, ABRP...
The existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. Although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...
Backup utilities for the Windows environment are designed to work with the NTFS file format, but they typically provide only partial compatibility with Alternate Data Streams (ADSs). In particular, computer forensics tools are typically capable of discovering ADSs in the file system under investigation, but not necessarily in the backups of such file systems. We examined a number of commonly us...
An on-line backup function for X-NAS, a clustered NAS system designed for entry-level NAS, has been developed. The on-line backup function can replicate file objects on XNAS to a remote NAS in real-time. It makes use of the virtualized global file system of X-NAS, and sends NFS write operations to both X-NAS and the remote backup NAS at the same time. The performance of the on-line backup funct...
For some real-time applications, it is necessary to provide a fast switch over to the backup connection whenever the primary connection fails. With the increase in reliability of network links, it is more cost effective if the backup resources are shared among a number of connections. However, the sharing of backup resources must be controlled to ensure the users of high availability of the bac...
A Network Differential Backup and Restore System based on a Novel Duplicate Data Detection algorithm
The ever-growing volume and value of data has raised increasing pressure for long-term data protection in storage systems. Moreover, the redundancy in data further aggravates such pressure in these systems. It has become a serious problem to protect data while eliminating data redundancy, saving storage space and network bandwidth as well. Data deduplication techniques greatly optimize storage ...
In a remote backup system, transaction processing takes place at the primary and the log records generated at the primary are propagated to the remote backup which uses them to reconstruct a recent state of the database at the primary. In the event of a primary failure, the backup system takes over transaction processing without causing users to observe a breach in service. Existing remote back...
CERNBox is the cloud collaboration hub at CERN. The service has more than 37,000 user accounts. backup of and project spaces data critical for service. underlying storage system hosts over a billion files which amount to 12PB distributed thousands disks with tworeplica layout. Performing operation this vast number non-trivial task. original (an in-house event-driven file-level system) been reco...
