What Is Cloud-Based Backup and Recovery?
White paper Cover Image Pick an image that is accurate and relevant to the content, in a glance, the image should be able to tell the story of the asset 550x450 What is cloud-based backup and recovery? Q120-20057 Executive Summary Companies struggle with the challenges of effective backup and recovery. Small businesses lack dedicated IT resources to achieve and manage a comprehensive data protection platform, and enterprise firms often lack the budget and resources for implementing truly comprehensive data protection. Cloud-based backup and recovery lets companies lower their Cloud-based backup and recovery lets data protection cost or expand their capabilities without raising costs or administrative overhead. Firms of all sizes can companies lower their data protection benefit from cloud-based backup and recovery by eliminating cost or expand their capabilities without on-premises hardware and software infrastructure for data raising costs or administrative overhead.” protection, and simplifying their backup administration, making it something every company should consider. Partial or total cloud backup is a good fit for most companies given not only its cost-effectiveness, but also its utility. Many cloud- based backup vendors offer continuous snapshots of virtual machines, applications, and changed data. Some offer recovery capabilities for business-critical applications such as Microsoft Office 365. Others also offer data management features such as analytics, eDiscovery and regulatory compliance. This report describes the history of cloud-based backup and recovery, its features and capabilities, and recommendations for companies considering a cloud-based data protection solution. What does “backup and recovery” mean? There’s a difference between “backup and recovery” and “disaster recovery.” Backup and recovery refers to automated, regular file storage that enables data recovery and restoration following a loss. -

Chapter 16 Disk Storage, Basic File Structures, Hashing, and Modern Storage - Databases are stored as files of records stored on disks - Physical database file structures - Physical levels of three schema architecture 1 - The collection of data in a DB must be stored on some storage medium. The DBMS software can retrieve, update, and process this data as needed - Storage media forms a hierarchy 2 -primary, secondary, tertiary, etc.. - offline storage, archiving databases (larger capacity, less cost, slower access, not directly accessible by CPU) Memory Hierarchies and Storage Devices - Cache, static RAM (Prefetch, Pipeline) - Dynamic RAM (main memory( Secondary and Tertiary Storage -mass storage (magnetic disks, CD, DVD (measured in KB, MB, TB, PB - programs are in main memory (DRAM) -permanent databases reside in secondary storage - main memory buffers are used to read and write to secondary storage - Flash memory: non volatile, NAND and NOR flash based - Optical disks: CDs (700MB) and DVDs (4.5 – 15GB), Blue Ray (54GB) - Magnetic Tapes and Juke Boxes Depending upon the intended use and application requirements, data is kept in one or more levels of hierarchy 3 Storage Organization of Database -Large amount of data that must persist for a long period of time (called persistent data) - parts of this data are accessed and processed repeatedly during the storage period - transient data during the period of execution - most DBs are stored on secondary storage (magnetic disks) - DB is too large to fit in main memory - permanent loss on disk is less likely - less cost on disk than primary storage 4 5 6 - A range of cylinders have the same number of sectors per arc. -

Secure Data Storage – White Paper Storage Technologies 2008
1 Secure Data Storage – White Paper Storage Technologies 2008 Secure Data Storage - An overview of storage technology - Long time archiving from extensive data supplies requires more then only big storage capacity to be economical. Different requirements need different solutions! A technology comparison repays. Author: Dr. Klaus Engelhardt Dr. K. Engelhardt 2 Secure Data Storage – White Paper Storage Technologies 2008 Secure Data Storage - An overview of storage technology - Author: Dr. Klaus Engelhardt Audit-compliant storage of large amounts of data is a key task in the modern business world. It is a mistake to see this task merely as a matter of storage technology. Instead, companies must take account of essential strategic and economic parameters as well as legal regulations. Often one single technology alone is not sufficient to cover all needs. Thus storage management is seldom a question of one solution verses another, but a combination of solutions to achieve the best possible result. This can frequently be seen in the overly narrow emphasis in many projects on hard disk-based solutions, an approach that is heavily promoted in advertising, and one that imprudently neglects the considerable application benefits of optical storage media (as well as those of tape-based solutions). This overly simplistic perspective has caused many professional users, particularly in the field of long-term archiving, to encounter unnecessary technical difficulties and economic consequences. Even a simple energy efficiency analysis would provide many users with helpful insights. Within the ongoing energy debate there is a simple truth: it is one thing to talk about ‘green IT’, but finding and implementing a solution is a completely different matter. -

PROTECTING DATA from RANSOMWARE and OTHER DATA LOSS EVENTS a Guide for Managed Service Providers to Conduct, Maintain and Test Backup Files
PROTECTING DATA FROM RANSOMWARE AND OTHER DATA LOSS EVENTS A Guide for Managed Service Providers to Conduct, Maintain and Test Backup Files OVERVIEW The National Cybersecurity Center of Excellence (NCCoE) at the National Institute of Standards and Technology (NIST) developed this publication to help managed service providers (MSPs) improve their cybersecurity and the cybersecurity of their customers. MSPs have become an attractive target for cyber criminals. When an MSP is vulnerable its customers are vulnerable as well. Often, attacks take the form of ransomware. Data loss incidents—whether a ransomware attack, hardware failure, or accidental or intentional data destruction—can have catastrophic effects on MSPs and their customers. This document provides recommend- ations to help MSPs conduct, maintain, and test backup files in order to reduce the impact of these data loss incidents. A backup file is a copy of files and programs made to facilitate recovery. The recommendations support practical, effective, and efficient back-up plans that address the NIST Cybersecurity Framework Subcategory PR.IP-4: Backups of information are conducted, maintained, and tested. An organization does not need to adopt all of the recommendations, only those applicable to its unique needs. This document provides a broad set of recommendations to help an MSP determine: • items to consider when planning backups and buying a backup service/product • issues to consider to maximize the chance that the backup files are useful and available when needed • issues to consider regarding business disaster recovery CHALLENGE APPROACH Backup systems implemented and not tested or NIST Interagency Report 7621 Rev. 1, Small Business planned increase operational risk for MSPs. -
