What Is Disaster Recovery?
A disaster is a sudden catastrophic loss of data
Disaster recovery is the process of resuming normalbusiness operations as quickly as possible after thedisaster is over
Disaster recovery process includes:
Executing a written disaster recovery plan
Replacing any damaged hardware
Restoring data
Testing all hardware and software before resuming
operations

5/53
Guidelines for Preparing for Disaster Recovery
Create a disaster recovery plan for performing regularbackup operations
Test your backup files and your backup plan
Keep two sets of backed-up files: one on-site, for
accessibility, and one off-site, for security
Create a redundant copy of System State data
Install the Recovery Console as a startup option
Keep the installation CD where you can easily find it

Overview of Backing Up Data
Backing up produces copies of data files and folders,stored on alternate media
Backing up the data on server and client computer harddisks prevents data loss
Before backing up, decide:
Which files to back up if you cannot get along without it,back it up
How frequently to back up
Whether to perform a network backup weigh the advantages and
disadvantages of a network backup
Back Up Data

Who Can Back Up Data?
You must have certain permissions or user rights
Only administrators, backup operators, and server operatorgroups are allowed to back up data by default on local servers
Or you must be the owner of the files and folders you want to
back up
Or you must have one or more of these permissions:
Read, Read and execute, Modify, or Full Control
You cannot back up your files if there are disk quota restrictions
Access to backup files can also be restricted
For security, backup and restore rights can be segregated intotwo groups
Backup files and directories GPO located in ComputerConfiguration

What Is System State Data?
The computer uses System State data files to load, configure,and run the operating system
All System State data relevant to your server is backed up
You can back up the following system components:
ComponentWhen this component is included
in System State
Registry Always
Boot files, including the system files Always
Certificate Services database If it is a Certificate Services Server
Active Directory directory service If it is a Domain
SYSVOL Directory If it is a Domain Controller
Cluster service information If it is within a cluster
IIS metadirectory If it is installed
System files that are under Windows File Protection Always
