Backup Database
One of the most important tasks in maintaining a database is to ensure that all data is backed up. It is important to have data backups regularly and this is possible through SQL Server 2012. Policies and procedures need to be set in place in the event of a natural disaster, hardware loss or other unforeseen circumstances cause a loss in data. Database backup procedures need to be well defined and a copy of the backup needs to be stored at a secure location where it can be recovered. The loss of data to an organization can mean unnecessary delays in returning to normal business which in the end means loss of money.
Within SQL Server 2012, there are two primary commands for backup, the primary command is BACKUP DATABASE (, 2014). The BACKUP DATABASE command allows a backup to be completed of both databases and files (, 2014). A full database backup includes all databases as well as the transaction log in case files are needed to be restored (Microsoft SQL Server, 2014). A full database backup is a mirror of the database at the time the backup finished. Backing up a large database can be time consuming as well as take up a lot of space. If backing up a large database is too time consuming, differential database backups can be completed (Microsoft SQL Server, 2014). It is important to note that for a full backup, it is not sufficient to just backup data but transaction logs must also be backed up (Microsoft SQL Server, 2014).
An entire database can be restored in one step to any location. Restoring a database can take some time as all data must be recovered before the database can return online (Microsoft SQL Server, 2014). In the full recovery model, all transaction logs must be restored before the database can be recovered (Microsoft SQL Server, 2014). Transact-SQL permits backups using the BACKUP command…...

Backup Plan

...Please answer these questions as you prepare your backup plan: 1. If your primary computer is unavailable, where will you be able to do your course work? Some topics to consider when answering this question are computer crashes, internet outages, and hours computers are available at other places (library, campus, etc.). 2. If my ISP is not responding or is too slow, where can I find another internet connection fast enough to complete any timed assignments? The bulk of the course work this semester doesn't need a high speed connection, but if you have a very slow modem connection you may need to find another connection when taking tests and quizzes. 3. Where will you keep copies or backups of all important class documents and assignments? If your computer crashes, you will still need access to material previously covered. 4. Where can I keep my ISP and Blackboard passwords secure, yes easily accessible, in case my memory fails? 5. What are the phone numbers for my computer manufacturer's and ISP's support desks in case I have computer and/or internet problems? Your instructor won't be able to troubleshoot computer and connection problems so you must be prepared. The numbers should be in a secure, easily accessible location. 6. What are the phone numbers for the CNM helpdesk and Embanet (phone help for Blackboard)? What are the web addresses for these help services? This information should be in a secure, easily accessible location. 1.......

...A database is an organized collection of data. The data are typically organized to model relevant aspects of reality in a way that supports processes requiring this information. For example, modeling the availability of rooms in hotels in a way that supports finding a hotel with vacancies. Database management systems (DBMSs) are specially designed applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose database management system (DBMS) is a software system designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs includeMySQL, PostgreSQL, SQLite, Microsoft SQL Server,Oracle, SAP, dBASE, FoxPro, IBM DB2, LibreOffice Base and FileMaker Pro. A database is not generally portable across different DBMS, but different DBMSs can by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one database.

...most important things you can do to safeguard the data you create and store on your computer. To this end, Microsoft included a full backup and restore utility with Windows 7. Here’s how it works. Backing Up First you need to launch Windows' Backup and Restore utility. You will find it in the Control Panel by selecting first System and Security and then Backup and Restore. If you have never used this tool before, you'll see a message under 'Backup' that says 'Windows Backup has not been set up'. Click the link labeled Set up backup to the right of that message. After the program starts, it will prompt you to choose a location for it to store your backup files in. Windows won't let you choose your main hard drive as a backup drive; so if you haven’t already plugged in your external hard drive, do it now and click Refresh. After you've chosen the drive that you want to use for your backup, the program will ask you to identify what you want to back up. The default selection is to let Windows choose for you, and create a disk image at the same time. You can be much more selective, however, by clicking the radio button next to Let me choose. Once you've chosen what you want to back up, and where you want Windows to store it, the program will display a backup summary screen that confirms the options you selected. Before you run your backup, though, you'll probably want to take a look at the default schedule that Windows has set up for you, to confirm that your computer......

Active Directory Backup

...1. Define the two types of backups supported by Active Directory. Describe the difference between each of these backup strategies; how they are implemented and what tools can be deployed to accomplish these tasks. Active directory has two different types of backups. They are NTBACKUP and Windows Server Backup. The Windows Server Backup is the only “all in one” type of backup. It allows you to work with Volume Shadow Copy Service snapshots in Active Directory. The Window’s Server Backup lets you backup to direct-attached disk volumes, network shares, external hard drives and even DVD’s. You are also able to utilize Group Policy settings to help keep the files safe from people who should not have access to them. The next backup option is NTBACKUP which is a file based backup tool but it has been replaced with the Windows Server Backup. 2. Explain fragmentation. Compare and contrast online defragmentation and offline defragmentation. Fragmentation is when parts of a file are saved in several different areas on the hard disk instead of all together. Online defragmentation is an automated defragmentation process that runs on a schedule. With online defragmentation the physical size of the database is not reduced. Offline defragmentation is just the opposite of online. Offline defragmentation is used to shrink the database size by removing the unused spaces. 3. What factors must be considered and planned to implement a successful Disaster Recovery Plan for a......

...chapter 2 Database System Concepts and Architecture he architecture of DBMS packages has evolved from the early monolithic systems, where the whole DBMS software package was one tightly integrated system, to the modern DBMS packages that are modular in design, with a client/server system architecture. This evolution mirrors the trends in computing, where large centralized mainframe computers are being replaced by hundreds of distributed workstations and personal computers connected via communications networks to various types of server machines—Web servers, database servers, file servers, application servers, and so on. In a basic client/server DBMS architecture, the system functionality is distributed between two types of modules.1 A client module is typically designed so that it will run on a user workstation or personal computer. Typically, application programs and user interfaces that access the database run in the client module. Hence, the client module handles user interaction and provides the user-friendly interfaces such as forms- or menu-based GUIs (graphical user interfaces). The other kind of module, called a server module, typically handles data storage, access, search, and other functions. We discuss client/server architectures in more detail in Section 2.5. First, we must study more basic concepts that will give us a better understanding of modern database architectures. In this chapter we present the terminology and basic concepts that will be used......

...Database: Database is a group or collection of information which are assembled in such a way that a computer program can easily access the stored information and select required pieces of data. Databases are characterized in such a way that that it helps to store, retrieve, modify and delete data which is linked with various data processing operations. Advantages of Databases: • It helps to control data redundancy by centralizing databases although it is not necessary to eliminate all redundancy because sometimes it is used to store multiple copies of data due to business and technical reasons. • It helps to enforce integrity by enforcing specific integrity constraints which increases data integrity and independence of application programs. • It improves data security by restricting unauthorized access. • It helps to create an environment in which end users have easy access to data which helps them to respond quickly to changes in their environment. • It provides a backup for recovering from hardware or software failures. Disadvantages of Databases: • Database systems come at high cost which includes specific and sophisticated hardware, software and personnel for operating and maintaining this database system. • The complexity and breadth of functionality makes this system an extremely large piece of software which occupies large amount of disk space and requiring substantial amounts of memory to run efficiently. • There is a higher impact of failure due to the......

...Student Database Management System Ajay Shankar Bidyarthy , Abhishek Kumar November 13, 2012 Abstract: An organized and systematic office solution is essential for all universities and organizations. There are many departments of administration for the maintenance of college information and student databases in any institution. All these departments provide various records regarding students. Most of these track records need to maintain information about the students. This information could be the general details like student name, address, performance, attendance etc or specific information related to departments like collection of data. All the modules in college administration are interdependent. They are maintained manually. So they need to be automated and centralized as, Information from one module will be needed by other modules. For example when a student needs his course completion certificate it needs to check many details about the student like his name, reg number, year of study, exams he attended and many other details. So it needs to contact all the modules that are office, department and examination and result of students. With that in mind, we overhauled the existing Student Database Management System and made necessary improvement to streamline the processes. Administrators using the system will find that the process of recording and retrieving students information and managing their classes,......

...IST 792 paper 2 Database security is a growing concern evidenced by an increase in the number of reported incidencets of loss of unauthorized exposure to sensitive data. As the amount of data collected, retained, and shared electronically expands, so does the need to understand database security. (Murray, 2010) Database security concerns the use of a broad range of information security controls to protect databases (potentially including the data, the database applications or stored functions, the database systems, the database servers and the associated network links) against compromises of their confidentiality, integrity and availability. It involves various types or categories of controls, such as technical, procedural/administrative and physical. Database security is a specialist topic within the broader realms of computer security,information security and risk management. Security risks to database systems include, for example: * Unauthorized or unintended activity or misuse by authorized database users, database administrators, or network/systems managers, or by unauthorized users or hackers (e.g. inappropriate access to sensitive data, metadata or functions within databases, or inappropriate changes to the database programs, structures or security configurations); * Malware infections causing incidents such as unauthorized access, leakage or disclosure of personal or proprietary data, deletion of or damage to the data or programs, interruption or denial......
