Maker Quick Response Code in Visual C# Files that are open in other applications Files that Backup skips by default

Files that Backup skips by default include temporary files, such as Pagefile.sys, Hiberfil.sys, the ASR log file, the ASR error file, temporary files, and other files. These files are neither backed up nor restored by Backup. To display or configure which files Backup skips during a backup operation, do the following: 1. Open Backup, and then click Advanced Mode. 2. In the Backup Utility dialog box, select Tools and then Options. 3. Select the Exclude Files tab. Backup also skips files on remote computers that are on a network share if the files are in use at the time of the backup.

Volume shadow copy technology provides an instant copy of the original volume. A shadow copy of the volume is made at the time a backup is initiated. Data is then backed up from the shadow copy instead of from the original volume. The original volume continues to change as the process continues, but the shadow copy of the volume remains constant. This is helpful if users need access to files while a backup is taking place. Other important advantages of this technology include the following:

A computer can be backed up while applications and services are running. Files are not skipped during the backup process.

Part II:

Files open at the time of the shadow copy appear closed on the shadow copy volume. The need for scheduling a backup window is eliminated. A backup window requires that applications be shut down to ensure a successful volume backup.

Using volume shadow copy technology, Windows XP Professional works with running applications to determine when a volume shadow copy occurs. The Volume Shadow Copy service then allows a backup application to access the volume and back it up. Applications continue running uninterrupted on the actual volumes. After the backup is completed and the data is saved on the backup media, the shadow copy is deleted. By default, Windows XP Professional uses free disk space on any NTFS volume to store a record of the differences between the original volume and the shadow copy volume. The data on the shadow copy volume exists only while the shadow copy is being taken. The amount of disk space temporarily consumed depends on how much file data on the volume has changed during backup. If sufficient temporary disk space is not available, Windows XP Professional cannot complete a volume shadow copy and Backup skips open files. Thus you must provide sufficient disk space to create a shadow copy of open files. Applications that can use Backup can register writer interfaces, which help coordinate the backup activity with the backup application. Windows XP Professional uses volume shadow copy technology by default. If you only want to back up a few files or directories, you might want to disable shadow copies to avoid delays. For more information about volume shadow copy technology, see Windows XP Professional Help and Support Center. Note

The Automated System Recovery (ASR) tool, an advanced option of the Backup Tool (NTBackup.exe), is new in Windows XP Professional. The ASR feature replaces the Emergency Repair Disk found in Windows 2000 and Windows NT 4.0. Use ASR to restore your system only if other disaster recovery tools are unavailable. ASR allows you to restore the operating system to a previous state so that you can start Windows XP Professional when other recovery methods do not work. For example, disk damage might prevent you from starting Windows XP Professional in normal or safe mode, or it might prevent you from using Recovery Console and Last Known Good Configuration. ASR gives you another way to start your system.
