Chapter 15: BACKING UP AND RESTORING SYSTEMS AND DATA 2

OVERVIEW

Back up and restore systems and data

Use Automated System Recovery (ASR) to recover a system

Use System Restore to recover configuration data

Use system startup and recovery tools


WINDOWS BACKUP UTILITY

Wizard Mode or Advanced Mode

Volume shadow copy

Automated System Recovery (ASR)


WINDOWS BACKUP MODES

Wizard Mode Advanced Mode

The Backup utility supports backups using the Backup Or Restore Wizard (Wizard Mode) or using dialog boxes and menus (Advanced Mode). Advanced Mode allows administrators to tailor a backup job more quickly, but most features of Advanced Mode are available in the Backup Or Restore Wizard as well.


VOLUME SHADOW COPY

Creates a snapshot of open files

Makes “best effort” copy of all files during backup

Requires NTFS file system


AUTOMATED SYSTEM RECOVERY (ASR)

Creates complete backup set for system recovery

Uses a floppy disk to store disk configuration

Requires Setup CD for restore operation

Note: It can be used in conjunction with the Windows XP Setup CD to restore a system.


PLANNING A BACKUP AND RECOVERY STRATEGY

Choosing a backup type

Setting a backup schedule

Determining what to back up

Planning for disaster recovery


BACKUP TYPES - Normal

Normal - A normal backup copies all selected files and marks each file as having been backed up (in other words, the archive attribute is cleared).

With normal backups, you need only the most recent copy of the backup file or tape to restore all of the files. You usually perform a normal backup the first time you create a backup set.


BACKUP TYPES - Incremental

Incremental - An incremental backup backs up only those files created or changed since the last normal or incremental backup. It marks files as having been backed up (in other words, the archive attribute is cleared).

If you use a combination of normal and incremental backups, you will need to have the last normal backup set as well as all incremental backup sets in order to restore your data.


BACKUP TYPES - Differential

Differential - A differential backup copies files created or changed since the last normal or incremental backup. It does not mark files as having been backed up (in other words, the archive attribute is not cleared).

If you are performing a combination of normal and differential backups, restoring files and folders requires that you have the last normal as well as the last differential backup.


BACKUP TYPES - Copy

Copy - A copy backup copies all selected files but does not mark each file as having been backed up (in other words, the archive attribute is not cleared).

Copying is useful if you want to back up files between normal and incremental backups because copying does not affect these other backup operations.


BACKUP TYPES - Daily

Daily - A daily backup copies all selected files that have been modified the day the daily backup is performed.

The backed-up files are not marked as having been backed up (in other words, the archive attribute is not cleared).


BACKUP TYPES – System State

System state, backs up: Registry

COM+ Class Registration database

Boot files, including the system files

Certificate Services database

Active Directory directory service

SYSVOL directory

Cluster service information

IIS Metadirectory

System files that are under Windows File Protection


MIXING BACKUP TYPES


CHOOSING WHAT TO BACK UP

Consider disaster recovery options.

Can the operating system be restored in other ways?

ASR or OEM recovery disk?


PLANNING FOR DISASTER RECOVERY

Plan for a range of disaster scenarios

Document recovery steps

Test your plan

Note: The worst situation for an administrator is to find that the backup tape contains no data after a disaster.


SELECTING BACKUP MEDIA

Disk drives

Removable storage

Network folders

Tape drives

SAN – Storage Area Network
