Automated System Recovery
Microsoft recommends that you regularly create Automated System Recovery (ASR) sets as part of an overall plan for system recovery so that you are prepared if the system fails. ASR should be a last resort for system recovery. Use ASR only after you have exhausted other options. For example, you should first try Safe Mode Boot and Last Known Good.ASR is a two-part system; it includes ASR backup and ASR restore. The ASR Wizard, located in Backup, does the backup portion. The wizard backs up the system state, system services, and all the disks that are associated with the operating system components. ASR also creates a file that contains information about the backup, the disk configurations (including basic and dynamic volumes), and how to perform a restore.The ASR backup process creates two items: 1)A full backup of the dirve on which Windows is installed and 2) An ASR floppy disk on which information that will help Windows use Automated System Recovery is stored.The ASR backup process creates two items: a full backup of the drive on which Windows is installed and an ASR floppy disk on which information that will help Windows use Automated System Recovery is stored.
Automatic system recovery is a device or process that detects a computer failure and attempts recovery. System Restore is a component of Microsoft's Windows Me, Windows XP, Windows Vista and Windows 7, but not Windows 2000, operating systems that allows for the rolling back of system files, registry keys, installed programs, etc., to a previous state in the event of system malfunction or failure.
The ASR backup process creates two items: a full backup of the drive on which Windows is installed and an ASR floppy disk on which information that will help Windows use Automated System Recovery (ASR) is stored.
