7-2+ Practice: Restoring Data

Practice: Restoring Data

In this practice, you will verify your backup and restore procedures using a common method: restoring to a test location.

Exercise 1: Verify Backup and Restore Procedures

To verify backup and restore procedures, many administrators will perform a test restore of a backup set. So as not to damage production data, that test restore is tar-geted not at the original location of the data, but at another folder, which can then be discarded following the test. In a production environment, your verification should include restoring the backup to a "standby" server, which would entail making sure that the backup device (that is, the tape drive) is correctly installed on a server that can host data in the event that the primary server fails. To do this, perform the following steps:

  1. 1. Open the Backup Utility.
  2. 2. Click Restore And Manage Media.
  3. 3. Click the plus sign to expand the file.

Lesson 2 Restoring Data 7-17

  1. 4. Click the plus sign to expand Backup-normal.bkf.
  2. 5. Click the check box to select C:.
  3. 6. Expand C:, Data, and Finance. You will notice that your selection of the C: folder has selected its child folders and files.
  4. 7. In the Restore Files To drop-down box, select Alternate Location.
  5. 8. In the Alternate Location field, type C:\TestRestore.
  6. 9. Click Start Restore.
  7. 10. In the Confirm Restore dialog box, click OK.
  8. 11. When the restore job is complete, click Report and examine the log of the restore operation.
  9. 12. Open the C:\TestRestore folder and verify that the folder structure and files restored correctly.
  10. 13. Repeat steps 1 through 10, this time restoring the file backup-diff-day2.bkf. When the restore job is finished, continue to step 14 to examine its report.
  11. 14. When the restore job finishes, click Report to view the restore job log. If you acci-dentally close the job status window, choose the Report command from the Tools menu, select the most recent report and click View.
  12. 15. Examine the report for the job you just restored. How many files were restored?

 

None.

Why?

The answer lies in the restore options.

  1. 16. Choose the Options command from the Tools menu and click the Restore tab. Now you can identify the problem. The default configuration of the backup utility is that it does not replace files on the computer. Therefore, the differential job, which contains files that were updated after the normal backup, was not success-fully restored.
  2. 17. Choose Always Replace The File On My Computer.
  3. 18. Repeat the restore operation of backup-diff-day2.bkf. The report should confirm that two files were restored.
  4. 19. You have now verified your backup and restore procedures, including the need to modify restore options. Delete the C:\TestRestore folder.

7-18 Chapter 7 Backing Up Data

Lesson Review

The following questions are intended to reinforce key information presented in this lesson. If you are unable to answer a question, review the lesson materials and try the question again. You can find answers to the questions in the "Questions and Answers" section at the end of this chapter.

  1. 1. A user has accidentally deleted the data in a Microsoft Word document and saved the document, thereby permanently altering the original file. A normal backup operation was performed on the server the previous evening. Which restore option should you select?
  2. a. Do Not Replace The File On My Computer.
  3. b. Replace The File On Disk Only If The File On Disk Is Older.
  4. c. Always Replace The File On My Computer.
  5. 2. An executive has returned from a business trip. Before the trip, she copied files from a network folder to her hard drive. The folder is shared with other execu-tives, who modified their files in the folder while she was away. When she returned, she moved her copy of the files to the network share, thereby updating her files with the changes she made while away, but also overwriting all the files that had been changed by other executives. The other executives are unhappy that their files have been replaced with the versions that were active when she left for her trip. Luckily, you performed a normal backup operation on the folder the previous evening. What restore option should you choose?
  6. a. Do Not Replace The File On My Computer.
  7. b. Replace The File On Disk Only If The File On Disk Is Older.
  8. c. Always Replace The File On My Computer.
  9. 3. You would like to test the restore procedures on your server, but would also like to avoid affecting the production copies of the backed-up data. What is the best restore location to use?
  10. a. Original location
  11. b. Alternate location
  12. c. Single folder

Lesson 2 Restoring Data 7-19

Lesson Summary

The Backup Utility will also allow you to restore backed-up data.

When restoring a lost file or folder, it is common to select Original Location as the restore location.

When testing restore procedures, it is common to select Alternate Location as the restore location so that you do not affect the original copies of the backed-up files and folders.

When restoring a differential or incremental backup set after restoring the normal backup set, you will need to select the restore option Always Replace The File On My Computer.

When restoring a folder in which files have been lost, but some files are intact, you should select the restore option Do Not Replace The File On My Computer or Replace The File On Disk Only If The File On Disk Is Older.
