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

How to Back Up Data


7/53

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


8/53

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


9/53

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


10/53

What Is the Backup Utility?

Backup DataUsing the Backup utility, you can:

Back up files and folders

Back up System State data

Schedule a backup

Using volume shadow copy inBackup, you can:

Create shadow copy backups ofvolumes including all open files

Ensure that files that changed duringbackup process are copied correctly

You can back up various types ofmedia

You must have appropriatepermissions and user rights

Corrupted Data

Restore Data

12/53

What Is ntbackup?

Use ntbackup command line tool to:


Back up files to a file or a tape

Run batch files

Important limitations using batch filesYou can back up entire folders only

You cannot use wildcard characters


13/53

What Is an Automated System Recovery Set?

A recovery option in the Backup utility that containstwo parts: ASR backup and ASR restore

Can back up the operating system

Does not include data files

Creates a floppy disk, which contains information about:

Backup location data

Disk configurations (including basic and dynamic volumes)

Default shadow copy scheduleis 7:00 am and noon

Create a shadow copy schedule

based on:

Do most workers work in thesame time zone?

Does your organization need

more than the default of twoshadow copies daily?

How often can additionalcopies be made before

additional storage will beneeded?

Best Practices for Using Shadow Copies

Consider the work patterns of users before enabling shadowcopies and setting scheduling options

Do not enable shadow copies on volumes that use mountpoints

Do not enable shadow copies on dual-boot computers

Select a separate volume on another disk as the storage

area for shadow copies

Use Windows Backup to perform regular backups of your fileserver

Do not schedule copies to occur more often than once perhour

Before deleting a volume that is being shadow copied, deletethe scheduled task for creating shadow copies

Uses default settings:

VGA modeMouse driver

No network connections

Minimum device drivers required to start Windows

You can use safe mode to:

Change server settings

Diagnose problemsRemove newly installed software

Install a service pack or hotfix

Reinstall the operating system

Option Description Use

Safe ModeStarts with only basic files

and drivers

When you suspect a recentlyinstalled application is causingthe problem

Safe Mode

with

Networking

Starts with only basic filesand drivers, plus network

connections

When you need to verify thatthe networking subsystem is

operational

What Is the Recovery Console?


45/53

With Recovery Console, you can:

What Is the Recovery Console?

Enable or disable device drivers or services

Copy files from the installation CD for the operatingsystem, or copy files from other removable media

Create a new boot sector and new master boot record(MBR)

Starts a command-line console on a system in which asoftware problem is preventing the system from

startingAccesses drives on your computer



46/53



Install the Recovery ConsoleStart and use the Recovery Console from the WindowsServer 2003 Setup CD

Start and use the Recovery Console from the boot

loader menu on the server



47/53


Allows you to access a disk drive with a faulty boot sequence,for example:

Damaged boot sector

Damaged master boot record (MBR)

Virus infections

Missing or damaged Ntldr or Ntdetect.com files

Incorrect Ntbootdd.sys driver

To boot from the shadow of a broken mirror

Windows Startup disk must include

Ntldr

Ntdetect.com

Boot.ini

How Boot Files Function


48/53

BIOS reads the contentsof the MBR1

Boot sector program readsthe root directory and loadsWindows 2003 Loader

2

NTLDR loads basic memoryconfiguration and switches to32-bit mode (protected mode)

3

NTLDR reads boot.iniand runs OS4

NTLDR switches back to 16-bit mode, loads ntdetect.com5

NTLDR loads into memory,reads the resource map thatNTDETECT builds

6

NTLDR switches system backto protected mode7

NTLDR starts run process forNTOSKRNL8
