  1. Module 11: Managing Data Storage

  2. Overview • Managing File Compression • Configuring File Encryption • Configuring EFS Recovery Agents • Implementing Disk Quotas

  3. Lesson: Managing File Compression • What Is File Compression? • What Is the compact Command? • What Are the Effects of Moving and Copying Compressed Files and Folders? • Best Practices for Compressing Files or Folders • Practice: Managing File Compression

  4. What Is File Compression? File A File B • Use compression to save disk space • Do not use compression for system files and folders • Compression is configured asan NTFS attribute • NTFS calculates disk spacebased on uncompressed file size • Compressed (zipped) foldersare also compressed

  5. What Is the compact Command? A command-line tool for compressing files and folders • Provides a good overview of compression states • Allows multiplefile names andwildcards

  6. What Are the Effects of Moving and Copying Compressed Files and Folders? Within an NTFS Partition Within an NTFS Partition A B Copy Move From NTFS Partitions To NTFS Partitions C Copy Move From NTFS Partition To FAT Partition D Copy Move Inherits Retains Inherits No Compression

  7. Best Practices for Compressing Files or Folders • Identify files that will benefit from compression • Do not compress system files • Do not compress already-compressed files • Compress static data rather than data that changes frequently

  8. Practice: Managing File Compression In this practice, you will: • Compress files • Move and copy compressed files

  9. Lesson: Configuring File Encryption • What Is EFS Encryption? • What Is Public-Key Encryption? • How EFS Uses Encryption • How EFS Uses Certificates • What Are the Effects of Moving and Copying Encrypted Files or Folders? • Sharing an Encrypted Folder • Practice: Configuring File Encryption

  10. What Is EFS Encryption? EFS encryption makes data unintelligible without a decryption key • EFS encrypts data • Encryption keys are automatically generated if required • Opening and saving encrypted files is transparent to users • Use the cipher command to display or alter encryption of folders and files on NTFS volumes

  11. What Is Public-Key Encryption? • Public key • Private key • Certification authorities • Automated certificate creation

  12. How EFS Uses Encryption • Symmetric encryption protects the file • Symmetric encryption is strong and fast • Public-key encryption protects the symmetric key • A copy is stored for each user • A copy is stored for the recovery agent

  13. How EFS Uses Certificates • Certificate identifies user • EFS generates a certificate • Requests from CA • Self-signed if CA not available • EFS renews certificates if required

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

  15. Sharing Encrypted Files • Encrypted files can be shared with local, domain, and trusted domain users • Groups cannot be authorized for access • Any user with access can add other users • Self-signed certificates are difficult for sharing

  16. Practice: Configuring File Encryption In this practice, you will: • Encrypt a folder • Share an encrypted file • Identify the effects of moving and copying compressed files and folders

  17. Lesson: Configuring EFS Recovery Agents • What Is an EFS Recovery Agent? • Recovering Encrypted Files • Practice: Configuring EFS Recovery Agents

  18. What Is an EFS Recovery Agent? • Authorized to decrypt data • Required when users are deleted • Required when local user passwords are reset • The recovery key can be exported

  19. Recovering Encrypted Files • Log on as recovery agent • Recovery policies define the recovery agent • Default recovery agent is the domain Administrator account • Back up the recovery key

  20. Practice: Configuring EFS Recovery Agents In this practice, you will: • Configure an EFS recovery agent • Export an EFS recovery certificate

  21. Lesson: Implementing Disk Quotas • Multimedia: What Are Disk Quotas? • What Are Disk-Quota Settings? • Practice: Implementing Disk Quotas

  22. 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

  23. What Are Disk-Quota Settings? • Track and control user NTFS volume space • Restrict storage to quotas • Trigger log events • Calculated with uncompressed file size • Quota entries

  24. Practice: Configuring Quota Limits In this practice, you will: • Configure quota limits • Add a quota entry

  25. Lab: Managing Data Storage In this lab, you will: • Troubleshoot disk-quota entries • Recover an encrypted file
