Windows Recovery Option Types
There are many Windows recovery methods.
Automated System Recovery (ASR) :
Automated System Recovery (ASR) is a Windows XP process that uses backup data and the Windows installation source ﬁles to rebuild a failed computer system. To perform ASR, you will need:
- The Windows installation CD-ROM.
- An ASR disk, which provides the information Windows Setup needs to run ASR recovery.
- An ASR backup set that contains a complete copy of the Windows system ﬁles and all conﬁguration information.
Emergency Repair :
Although ASR is not supported in Windows 2000, both Windows 2000 and Windows XP support an alternate recovery method called Emergency Repair. When you install Windows, the system stores information about the conﬁguration of the operating system in a hidden folder called \Windows\Repair. If your installation is damaged, you may be able to repair it by using this information and the Windows Setup program. You might want to try a repair installation as an intermediate step before attempting ASR or a complete reinstall.
In Windows 2000, you can create a copy of the repair information on a ﬂoppy disk called an emergency repair disk (ERD). Since ﬂoppy disks and ﬂoppy drives are increasingly rare, this has been replaced by an Emergency Repair CD in Windows XP. When you create an ERD, the system also updates the contents of the \Repair folder.
Complete PC Backup and Restore :
ASR and Emergency Repair are not supported in Windows 7. Instead, the Complete PC Backup and Restore tool creates an image of your entire computer, and this can be used to recover from a failure, allowing complete restoration of the operating system, installed programs, settings, and ﬁles.
System Repair Disk :
Windows 7 allows for the creation of a system repair disk. This disk can be used to access system recovery options if you do not happen to have a Windows 7 installation disk handy. To use this option, you must create the disk from the Backup and Restore menu, and you will need to set the BIOS to boot from a CD/DVD when you insert your repair disk into the drive. The System Repair Disk allows you to access:
- Startup Repair
- System Restore
- System Image Recovery
- Windows Memory Diagnostic
- Command prompt
Repair install :
In Windows XP, you can replace system ﬁles with the ﬁles on the XP CD used for the Repair Install. Your applications and settings will be left intact, but any Windows updates will need to be reinstalled.
Factory Recovery Partition :
Sometimes a computer manufacturer will supply a recovery partition or CD-ROM (sometimes called a Recovery CD, or a Recover CD) that you can use to restore a computer to the conﬁguration it was in when it shipped from the manufacturer. Note that the Recovery Partition/CD-ROM not only restores the operating system, but also all applications that came pre-installed on the computer. Some manufacturers store the necessary information in a hidden partition on the computer’s hard disk. Others store this information on a CD-ROM. The steps you use to perform this type of recovery are manufacturer-speciﬁc. Review the documentation that came with the computer to determine how to perform the recovery.
Phases in the ASR Process
The ASR process consists of the following phases:
1. To prepare for ASR, an administrator uses Windows Backup to create an ASR backup set and ASR ﬂoppy disk.
- The ASR backup set must be stored on local backup media, not on a network drive.
- The ASR backup set cannot be stored on the same hard disk as the Windows installation, as this disk can be re-initialized during the ASR process.
2. If the system suffers a complete and catastrophic failure, the administrator selects a computer to use to restore the system.
3. The administrator runs Windows Setup from the Windows installation CD-ROM and initiates ASR.
4. The administrator provides the ASR ﬂoppy disk.
5. The system passes the information in the Setup Information Files (SIF) on the ASR ﬂoppy disk to Windows Setup.
6. Windows Setup installs the operating system as speciﬁed on the ASR ﬂoppy disk.
7. The administrator provides the ASR backup set.
8. ASR conﬁgures the system according to the information in the backup set.
