1. Module 7:
Managing Data Storage

2. Overview
 Managing Data Compression
 Managing Disk Quotas
 Encrypting Data
 Using Disk Defragmenter
 Troubleshooting Data Storage

3.  Managing Data Compression
 Defining Compressed Files and Folders
 Compressing Files and Folders
 Copying and Moving Compressed Files and Folders
 Best Practices for Managing Data Compression

4. Defining Compressed Files and Folders
 Files and Folders Have a Compression State
 Windows 2003 Automatically Uncompresses Accessed
Files
 Space Allocation Based on Uncompressed File Size
 Display Color Designates Compressed Files and Folders
W FolderA

FileA
FileB NTFS Partition

5. More
 Use compression when you need more space on your
hard-disk drive.
 Compressing files, folders, and programs decrease their
size and reduces the amount of space they use on
drives or removable storage device. You can also
compress disk drives.

6. More
 Space allocation : when files are copied, NTFS
calculates disk space based on the size of the
uncompressed file. This is important because
files are uncompressed during the copy process
and the system must be sure there is enough
space for the uncompressed file. If you copy a
compressed file to an NTFS partition that does
not have enough space for the uncompressed
file, an error message notifies you that there is
not enough disk space for the file.

10.  Managing Disk Quotas = quantium
 Defining Disk Quotas
 Using Disk Quotas
 Setting Disk Quotas

 Best Practices for Managing Disk Quotas

11. Defining Disk Quotas
 Usage Calculation Based on File and Folder Ownership
 Compression Ignored When Calculating Usage
 Free Space Reported to Applications Is Based on Quota
 Windows 2003 Tracks Disk Quotas for Each NTFS
Partition
 Only Available on NTFS Partitions

12. Using Disk Quotas
Allocated to User1 Allocated to User2
NTFS Allocated to User3
Partition
Allocated to User4
Disk 50-MB disk quota

Quota 40-MB warning level
 Set Limits to Control Hard Disk Space Usage
 Monitor Partition Usage on a Per-User Basis

13. Setting Disk Quotas

Set Quota Limits for Partitions on Shared Client Computers
Log On as Administrator to Install Components and Applications
Generate Disk Usage Information
Set Restrictive Default Limits; Modify Specific Disk Quota Entries
Set Quotas on Shared Partitions
Enable Quotas Before a Partition Is Used
Delete Quota Entries for Inactive Users
