1. Introducing NTFS Reliability Security Long file names Efficiency
(Skill 2)
Introducing NTFS
Reliability
NTFS is a recoverable file system
Volumes can be created that do not result in data loss in the event of a server crash or power failure
Security
You can secure data by setting up permissions to control user access to files and folders
Long file names
NTFS natively allows file names to be up to 256 characters in length
Efficiency
NTFS is required in order to use certain features, such as Active Directory, which stores and manages network resources efficiently
Faster access
NTFS minimizes the number of disk accesses required to find a file, which increases access speed

2. Compressing and Encrypting Data on an NTFS Volume
(Skill 3)
Compressing and Encrypting Data on an NTFS Volume
Data compression
Built-in feature that increases available storage on a hard disk
In NTFS volumes, you can compress only specific files and folders or the entire volume
When you add a new file or folder to a compressed folder, it is compressed automatically
You cannot compress an encrypted file
Data encryption
A security technique that attempts to ensure the confidentiality of a document by scrambling it using an encryption key
You cannot encrypt a compressed file

12. Setting NTFS Permissions
(Skill 5)
Setting NTFS Permissions
NTFS permissions
Restrict unauthorized access to files and folders
Secure network resources by controlling the level of access for each user
Standard NTFS folder permissions
Read
Write
List Folder Contents
Read & Execute
Modify
Full Control

13. Setting NTFS Permissions (3)
(Skill 5)
Setting NTFS Permissions (3)
When you apply permissions to a drive or folder, you are also applying those permissions to all files and folders underneath it, by default
Guidelines for assigning NTFS permissions
Create folders to organize data into categories
Assign users the lowest level of permissions required for them to perform their jobs
Assign the Read and Write permissions to the Users group
Avoid assigning the Full Control Permission for a folder
Deny permissions sparingly
Assign permissions to groups rather than to individual user accounts

(Skill 5)
Setting NTFS Permissions (4)
Other important factors
NTFS permissions can be inherited
Assign multiple NTFS permissions
NTFS file permissions override NTFS folder permissions
A denied permission overrides an allowed permission

20. Introducing Distributed File System
(Skill 8)
Introducing Distributed File System
Distributed file system (Dfs)
Allows users to locate files and folders spread across the network quickly and easily
Dfs topology
A hierarchical structure
Includes a Dfs root, one or more Dfs links, and one or more Dfs shared folders, or replicas, to which each Dfs link points
Dfs root
A local share that acts as the starting point and host to other shared resources
One server or domain is chosen as the Dfs root, which is stored on the physical server running the Dfs service

22. Introducing Distributed File System (2)
(Skill 8)
Introducing Distributed File System (2)
Types of Dfs roots
Stand-alone
Configured locally on a computer
Stores all of the information in the local Registry
Consists of only a single level of Dfs links
Does not provide data backup or replication
Domain
Also known as a fault-tolerant root
Is integrated with Active Directory

23. Introducing Distributed File System (3)
(Skill 8)
Introducing Distributed File System (3)
Dfs advantages
Easy access to network resources
Simplified network administration
Support for fault tolerance and load balancing
Support for network permissions
Integration with Internet Information Services (IIS)
