MANAGING DISKS AND FILE SYSTEMS

1
MANAGING DISKS AND FILE SYSTEMS

• Chapter 3

2
OVERVIEW

• Monitor and configure disks
• Monitor, configure, and troubleshoot volumes
• Monitor and configure removable media, such as
  tape devices
• Install, configure, and manage DVD and CD-ROM
  devices
• Configure NTFS, FAT32, and FAT file systems
• Use disk optimization utilities Disk
  Defragmenter, Chkdsk, and Disk Cleanup

3
DISK MANAGEMENT

• Types of storage
• Setting up hard disks
• Adding new disks
• Managing disks on remote systems

4
BASIC VS. DYNAMIC STORAGE
5
PARTITIONING A BASIC DISK
6
VOLUMES ON A DYNAMIC DISK

• Simple
• Spanned
• Striped

7
UPGRADING BASIC DISKS TO DYNAMIC DISKS
8
USING DISK MANAGEMENT TO MANAGE PARTITIONS,
STORAGE TYPE, AND VOLUMES

• Demonstration of Disk Management

9
MANAGING STORAGE ON REMOTE SYSTEMS
10
REMOVABLE STORAGE MANAGEMENT
11
MEDIA POOLS

• Free
• Import
• Unrecognized
• Application-specific

12
MANAGING COMPRESSION

• Compression methods
• Compressed folders
• NTFS compression

13
COMPRESSED FOLDERS

• Compatible with Zip compression programs
• Can be stored on FAT volumes and removable media
• Can be e-mailed

14
NTFS COMPRESSION

• Managed by the NTFS file system
• Automatically compresses and uncompresses files
• Managed via compression attributes on files and
  folders

15
MOVING OR COPYING COMPRESSED FILES

• Within an NTFS volume
• Moved files retain their compression attribute.
• Copied files inherit the attribute of the target
  folder.
• Between NTFS volumes
• All files inherit the attribute of the target
  folder.
• To FAT or FAT32 partitions
• Files are uncompressed. (FAT does not support
  compression.)

16
ENCRYPTING FILE SYSTEM

• Based on public key cryptography
• 256-bit Advanced Encryption Standard (AES)
  encryption
• Incompatible with NTFS compression
• Recovery agent can recover encrypted files

ENCRYPTING FILES
18
DECRYPTING FILES
19
COPYING OR MOVING ENCRYPTED FILES

• Moving or copying a file into an encrypted folder
  encrypts it.
• Moving or copying an encrypted file to an
  unencrypted folder does not decrypt it.
• Copying or moving an encrypted file to another
  file system decrypts it.
• Moving or copying a file requires decryption
  ability.
• Files can be backed up in the encrypted state.

20
SHARING ENCRYPTED FILES

• The owner of an encrypted file can add additional
  users.
• Works with files only.
• One file at a time can be shared.
• EFS is administered via the Details dialog box
  under Advanced Attributes for the encrypted file.

21
SHARING ENCRYPTED FILES (CONTINUED)
22
RECOVERING ENCRYPTED FILES

• The encrypted file must be recovered by the key
  used in the DRF.
• If the recovery key certificate is lost, the file
  cannot be recovered.
• The recovery agents certificate should be
  protected.

23
DISK QUOTAS

• Per-user limits on data storage.
• Limits the space per volume.
• Space determination based on uncompressed file
  size.
• Configured by default to all users.
• Individual users can be excepted with an
  individual quota.

SUMMARY

• The Disk Management snap-in manages local and
  remote disks.
• Use Disk Management to create volumes and format
  disks.
• Basic disks contain partitions dynamic disks use
  volumes.
• NTFS compression and encryption are not
  compatible.
• EFS encrypts data on NTFS volumes.

28
SUMMARY (CONTINUED)

• Protect the EFS recovery agents certificate to
  avoid losing files.
• Use Disk Defragmenter, Chkdsk, and Disk Cleanup
  to optimize and repair disks.
