Provable Ownership of Encrypted Files in De-Duplication Cloud Storage
1 Provable Ownership of Encrypted Files in De-duplication Cloud Storage Chao Yangy z, Jianfeng May and Jian Renz ySchool of CS, Xidian University Xi’an, Shaanxi, 710071. Email: fchaoyang, [email protected] zDepartment of ECE, Michigan State University East Lansing, MI 48824. Email: fchaoyang, [email protected] Abstract—The rapid adoption of cloud storage services has tells a client that it does not have to upload the file, it created an issue that many duplicated copies of files are stored in means that some other clients have the same file, which the remote storage servers, which not only wastes the communica- could be a sensitive information [5]. More seriously, Halevi tion bandwidth for duplicated file uploading, but also increases the cost of security data management. To solve this problem, et al. recently found some new attacks to the client-side client-side deduplication was introduced to avoid the client from deduplication system [6]. In these attacks, by learning just uploading files already existed in the remote servers. However, the a small piece of information about the file, namely its hash existing scheme was recently found to be vulnerable to security value, an attacker is able to get the entire file from the server. attacks in that by learning a small piece of information related These attacks are not just theoretical. Some similar attacks to the file, such as the hash value of the file, the attacker may be able to get full access of the entire file; and the confidentiality that were implemented against Dropbox were also discovered of the date may be vulnerable to “honest-but-curious” attacks. -
Improving Read Performance with BP-Dags for Storage-Efficient File Backup
Send Orders for Reprints to [email protected] 90 The Open Electrical & Electronic Engineering Journal, 2013, 7, 90-97 Open Access Improving Read Performance with BP-DAGs for Storage-Efficient File Backup Tianming Yang*, Jing Zhang and Ningbo Hao International College, Huanghuai University, Henan, 463000, China Abstract: The continued growth of data and high-continuity of application have raised a critical and mounting demand on storage-efficient and high-performance data protection. New technologies, especially the D2D (Disk-to-Disk) de- duplication storage are therefore getting wide attention both in academic and industry in the recent years. Existing de- duplication systems mainly rely on duplicate locality inside the backup workload to achieve high throughput but suffer from read performance degrading under conditions of poor duplicate locality. This paper presents the design and perform- ance evaluation of a D2D-based de-duplication file backup system, which employs caching techniques to improve write throughput while encoding files as graphs called BP-DAGs (Bi-pointer-based Directed Acyclic Graphs). BP-DAGs not only satisfy the 'unique' chunk storing policy of de-duplication, but also help improve file read performance in case of poor duplicate locality workloads. Evaluation results show that the system can achieve comparable read performance than non de-duplication backup systems such as Bacula under representative workloads, and the metadata storage overhead for BP-DAGs are reasonably low. Keywords: Data De-duplication, File Backup, Storage-Efficient, Read Performance. 1. INTRODUCTION schemes are emerging to provide more storage-efficient and high performance data protection for enterprises [9-13]. Data explosion [1] has been forcing backups to expand storage capacity, which makes modern enterprises face sig- In de-duplication, files or streams are divided into chunks nificant cost pressures and data management challenges. -

Bacula Regression Testing Bacula Community Version
Bacula Regression Testing Bacula Community Version This document is intended to provide insight into the considera- tions and processes required to implement regression testing with the Community Version of Bacula.

Copyright © December 2018 Bacula Systems www.baculasystems.com/contactus................................... All trademarks are the property of their respective owners 1 Bacula Regression Testing If you decided to install Bacula from source, and want to be as sure as possible that your self-compiled binaries behave as expected, the regression testing suite included with the source code is the best way to do so. You do not need to be a developer to run the regression scripts. If you installed Bacula from packages, going through the regression tests can be a reasonable way to ensure that everything behaves as expected and can be an important part of the pre-production testing routine. The tests are shell scripts that drive Bacula through bconsole and then typically compare the input and output with diff, so no particular infrastructure beyond what you needed to build Bacula and what is part of a typical Unix / Linux system is required. To get started, we recommend that you create a directory named bacula, under which you will put the current source code and the current set of regression scripts. The directory could have any name you like, though. Note, all the standard regression scripts run as non-root and can be run on the same machine as a production Bacula system. -

Madria Copyright 2017 MORTADA ABDULWAHED AMAN All Rights Reserved iii ABSTRACT Cloud computing, a technology that enables users to store and manage their data at a low cost and high availability, has been emerging for the past few decades because of the many services it provides. One of the many services cloud computing provides to its users is data storage. The majority of the users of this service are still concerned to outsource their data due to the integrity and confidentiality issues, as well as performance and cost issues, that come along with it. -

The current Bacula Console comes in two versions: a shell interface (TTY style), and a GNOME GUI interface. Both permit the administrator or authorized users to interact with Bacula. You can determine the status of a particular job, examine the contents of the Catalog as well as perform certain tape manipulations with the Console program. In addition, there is a wx-console built with wxWidgets that allows a graphic restore of files. As of version 1.34.1 it is in an early stage of development, but it already is quite useful. Since the Console program interacts with the Director through the network, your Console and Director programs do not necessarily need to run on the same machine. In fact, a certain minimal knowledge of the Console program is needed in order for Bacula to be able to write on more than one tape, because when Bacula requests a new tape, it waits until the user, via the Console program, indicates that the new tape is mounted. -
