The module discusses tools that students will use to back up data, the different backup types, and planning issues involved in backing up data. The module then discusses the procedure of backing up data by using the Microsoft ® Windows ® 2000 Backup utility and the various options that students can set for a backup job. Finally, the module covers the procedure to restore data from a backup and the options that can be set for a restore job. There is one lab in this module. In it, students will back up data by using the Windows Backup utility, restore data that has been backed up by using the Windows Backup utility and create a scheduled backup job.

Introduction to Backing Up and Restoring Data ! Preparing to Back Up Data ! Backing Up Data ! Restoring Data ! Best Practices Backing up data is an important system administration task that you will perform regularly. Creating a backup copy of all important, sensitive data— both on individual computers and on a network—is necessary to be able to restore the data in case of data corruption. Due to the importance of data backup, you must create a regular backup schedule and adhere to it. This will help create the latest copy of data available for a restore operation when it is required. At the end of this module, you will be able to: !" Identify the purpose of backing up and restoring data and the permissions required for these tasks. !" Prepare for backing up data by identifying the folders to back up and the backup type and backup media to use. !" Back up data at a computer and over the network. !" Restore data—entire volumes or a single file. !" Apply best practices for backing up and restoring data. Slide Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn how to back up and restore data. 2 Module 10: Backing Up and Restoring Data Introduction to Backing Up and Restoring Data ! The Goal of Backing Up Data Is to Restore That Data If It Is Lost ! Permissions and User Rights Are Required to Back Up and Restore Data Backup Backup Backup Data Data Data Data Data Corruption Data Corruption Data Corruption Restore Restore Restore Data Data The efficient recovery of lost data is the goal of all backup jobs. A backup job is a single process of backing up data. Regularly backing up data on server and client computer hard disks prevents data loss because of disk drive failures, power outages, virus infections, and other accidents. If data loss occurs, and you have performed regular backup jobs based on careful planning, you can restore the lost data, whether a single file or an entire hard disk is involved. With Microsoft ® Windows ® 2000, you can use the Backup utility to back up and restore data easily. You can use Windows Backup to back up data manually or to schedule unattended backup jobs on a regular basis. You can back up data to a file or to a tape drive. You can store files on hard disks, removable disks and recordable compact discs and optical drives. To successfully back up and restore data on a computer running Windows 2000, you must have the appropriate permissions and user rights that the following list describes: !" All users can back up their own files and folders. They can also back up files for which they have the Read permission. !" All users can restore files and folders for which they have the Write permission. !" Members of the Administrators, Backup Operators, and Server Operators groups can back up and restore all files (regardless of the assigned permissions). By default, members of these groups have the Backup files and directories and Restore files and directories user rights. Slide Objective To introduce backing up and restoring data. Lead-in While maintaining a network, it is important to ensure that network data, such as Active Directory, is not lost. For this purpose, you use the Backup utility. Delivery Tip The slide for this topic is animated. The icon on the lower left corner indicates the animated slide. Use this slide to explain why data backup is an important task. The animation begins with the process of data backup, then it presents the data becoming corrupt, and finally it depicts the data being restored from the back up copy. Key Points The goal of all backup jobs is to successfully restore lost and corrupt data. A user must have the appropriate user right or permission to back up and restore data. Module 10: Backing Up and Restoring Data 3 # Preparing to Back Up Data ! Planning Issues for Windows Backup ! Backup Types ! Examples of Backup Types You should plan your backup jobs to fit the needs of your organization. The primary goal for backing up data is to restore that data, so any backup plan that you develop should incorporate your restore strategy. The plan should also make it easy for you to restore lost critical data quickly and successfully. Part of the planning process is determining the backup type to use. A backup type helps define which data is backed up during a backup job. With Windows Backup, you can choose from a variety of backup types. Select the backup type that meets both your backup and restore needs. Slide Objective To introduce issues and concepts for backing up and restoring data. Lead-in Because the goal of backing up data is to restore the data when necessary, consider your restore goals when you prepare to back up data. Delivery Tip This section provides an overview of backing up data. Prepare students for the topic by providing the following key points of information. Key Points Plan backup jobs to incorporate your restore strategy. Determine the backup type to use based on the backup and restore needs of your organization. 4 Module 10: Backing Up and Restoring Data Planning Issues for Windows Backup Which Files and Folders to Back Up Which Files and Folders to Back Up How Often to Back Up How Often to Back Up Which Target Media to Use for Storing Backup Data Which Target Media to Use for Storing Backup Data Which Backup Type to Use Which Backup Type to Use Whether to Perform Network or Local Backup Jobs Whether to Perform Network or Local Backup Jobs Base your backup plan on the needs of your organization. There is no one correct backup plan for all networks. When formulating a backup plan, consider the following issues. Determine Which Files and Folders to Back Up Always back up critical files and folders that your organization needs to operate, such as sales and financial records, the registry for each server, and Active Directory ™ directory service. Periodically back up files that rarely change, such as monthly reports. Determine How Often to Back Up Back up critical data more often than non-critical data—typically daily. As a rule, back up data as often as it changes. If users create or modify reports once a week, then backing up the reports weekly is sufficient. Determine Which Target Media to Use for Storing Backup Data With Windows Backup, you can back up to the following removable media: !" Files. You can store the files on a removable media device or on a network location, such as a file server. Users can back up their personal data to a network server. Use this type of removable media for temporary backup jobs only. !" Tape drive. A less expensive removable medium than others, a tape drive is more convenient for large backup jobs because of its high storage capacity. However, tapes have a limited life and can deteriorate. Be sure that you check the manufacturer recommendations for use. If you use a removable media device to back up and restore data, be sure that you verify that the device is supported on the Windows 2000 Hardware Compatibility List (HCL). Slide Objective To present the issues to consider when planning a backup job. Lead-in Before you back up files, you should develop a backup strategy that suits your organization. To develop this strategy, consider these issues.
