1 Module 6: Managing Data Storage

2 Overview Managing File Compression Configuring File Encryption Implementing Disk Quotas

3 Lesson: Managing File Compression What Is File Compression? What Is the compact Command? How to Compress a File or Folder What Are the Effects of Moving and Copying Compressed Files and Folders? Best Practices for Compressing Files or Folders

4 What Is File Compression? A state of each file and folder on an NTFS partition Can also be Compressed (zipped) folders Does not necessarily reflect the compression state of the files in the folder Allocated disk space is based on uncompressed file size Use compression when you need more space on your hard drive Do not use compression for system files and folders File A File B

5 What Is the compact Command? A command-line tool that you can use to compress files and folders  Without parameters, compact displays compression state of current directory and any files it contains  You can also use multiple file names and wildcards

6 How to Compress a File or Folder Your instructor will demonstrate how to: Compress a file or folder on an NTFS drive Compress a file or folder using Compressed (zipped) Folders Compress a file or folder using the command-line tool compact Compress a file or folder on an NTFS drive Compress a file or folder using Compressed (zipped) Folders Compress a file or folder using the command-line tool compact

7 What Are the Effects of Moving and Copying Compressed Files and Folders? Folder on FAT Partition Folder on NTFS Partition D Between NTFS Partitions and Volumes Between NTFS Partitions C Within an NTFS Partition B A Copy Inherits Move Retains Inherits Copy Move Inherits Copy Move

8 Practice: Managing File Compression In this practice, you will:  Compress folders  Move and copy compressed files and folders and track the results

9 Best Practices for Compressing Files or Folders Determine which file types to compress Do not compress already compressed files or system files Compress static data rather than data that changes frequently

10 Lesson: Configuring File Encryption What Is EFS Encryption? How to Encrypt a File or a Folder What Are the Effects of Moving and Copying Encrypted Files or Folders?

11 What Is EFS Encryption? EFS encryption makes data unintelligible without a decryption key EFS encrypts data  Users encrypt a file or folder by setting the encryption property  All files and subfolders created in or added to an encrypted folder are automatically encrypted Use EFS to access encrypted data  When accessing an encrypted file, users can read the file normally  When users close the file, EFS encrypts it again Use EFS to decrypt data  The file remains decrypted until it is encrypted again Use the cipher command to display or alter encryption of folders and files on NTFS volumes EFS encrypts data  Users encrypt a file or folder by setting the encryption property  All files and subfolders created in or added to an encrypted folder are automatically encrypted Use EFS to access encrypted data  When accessing an encrypted file, users can read the file normally  When users close the file, EFS encrypts it again Use EFS to decrypt data  The file remains decrypted until it is encrypted again Use the cipher command to display or alter encryption of folders and files on NTFS volumes

12 How to Encrypt a File or Folder Your instructor will demonstrate how to: Encrypt files or folders by using Windows Explorer Encrypt offline files or folders by using Windows Explorer Encrypt files or folders by using the cipher command Encrypt files or folders by using Windows Explorer Encrypt offline files or folders by using Windows Explorer Encrypt files or folders by using the cipher command

13 What Are the Effects of Moving and Copying Encrypted Files or Folders? Encrypted Folder to Unencrypted Folder C Unencrypted File to Encrypted Folder B Unencrypted Folder to Encrypted Folder A Move = Copy = =

14 Practice: Configuring File Encryption In this practice, you will:  Configure file encryption  Move and copy encrypted files and folders

15 Lesson: Implementing Disk Quotas Multimedia: What Are Disk Quotas? What Are Disk Quota Settings? How to Enable and Disable Disk Quotas How to Add and Remove Disk Quota Entries How to Sort Quota Entries How to Import and Export Quota Settings to Another Volume

16 Multimedia: What Are Disk Quotas? This presentation explains the use of disk quotas as a method for managing data storage space and illustrates how disk quotas operate After viewing this presentation, you will be able to explain how to use disk quotas

17 What Are Disk Quota Settings? Track and control user’s disk space on NTFS volumes Prevent users from taking any additional disk space above their quota limit Log events when users near and exceed quota limits Can be enabled on local volumes, network volumes, and removable drives if they are formatted with NTFS Can be enabled on local computers and remote computers Cannot use file compression to prevent users from exceeding their limits Track and control user’s disk space on NTFS volumes Prevent users from taking any additional disk space above their quota limit Log events when users near and exceed quota limits Can be enabled on local volumes, network volumes, and removable drives if they are formatted with NTFS Can be enabled on local computers and remote computers Cannot use file compression to prevent users from exceeding their limits

18 How to Enable and Disable Disk Quotas Your instructor will demonstrate how to: Enable disk quotas by using Windows Explorer Disable disk quotas by using Windows Explorer Enable disk quotas by using Windows Explorer Disable disk quotas by using Windows Explorer

19 How to Add and Remove Disk Quota Entries Your instructor will demonstrate how to: Add a new quota entry Remove a disk quota entry Add a new quota entry Remove a disk quota entry

20 How to Sort Quota Entries Your instructor will demonstrate how to sort quota entries

21 How to Import and Export Quota Settings to Another Volume Your instructor will demonstrate how to: Export quota settings to another volume Import quota settings from another volume Export quota settings to another volume Import quota settings from another volume

22 Practice: Configuring Quota Limits In this practice, you will configure quota limits

23 Lab A: Managing Data Storage In this lab, you will:  Configure disk quotas entries  Export disk quota entries  Import disk quota entries  Compress a folder  Encrypt a folder
