Backing Up System State Data


System State data includes the following:

  • Boot files, including the system files

  • Files protected by Windows File Protection (WFP)

  • The registry

  • Performance counter configuration information

  • The Component Services class registration database

The System State data does not represent the entire system. To restore a system to an operational condition, the boot files, system volumes, and System State must all be restored together.

Restoration of the System State replaces boot files first and commits the system hive of the registry as a final step in the process.

System State backup and restore operations include all System State data. You cannot choose to back up or restore individual components because of dependencies among the System State components. However, you can restore System State data to an alternate location in which only the registry files and system boot files are restored. The Component Services class registration database is not restored to the alternate location.

Although you cannot change which components of the System State are backed up, you can back up all system-protected files at the same time as the System State data by setting advanced backup options.

The system-protected files only change if you install a service pack or application, or upgrade your operating system. Typically, the system-protected files represent a very large portion of System State data the default, including the protected files, is about 180 MB. Include these system-protected files only if new programs have been installed. Otherwise a restore causes the new application to fail.

To back up System State data

  1. From the Start menu, point to All Programs, click Accessories, click System Tools, and then click Backup.

  2. Click Advanced Mode.

  3. Click the Backup tab, and then select the System State check box.

  4. Click Start Backup.

This backs up the System State data along with any other data that you have selected for the current backup operation. Keep the following in mind when you are backing up System State data:

  • You must be an administrator or a backup operator to back up files and folders.

  • You can back up the System State data only on a local computer.

  • You must also back up the Boot and System volumes to ensure that the system starts properly.

  • You can use the Backup wizard to back up System State data.

  • You cannot use an incremental backup while backing up System State data.

Boot and System Files

Backup depends on the functionality of WFP when backing up and restoring boot and system files. System files are backed up and restored as a single entity. In Microsoft Windows NT version 4.0 and earlier, backup programs can selectively back up and restore operating system files as they do data files, allowing for incremental backup and restore operations of most operating system files. Windows XP Professional, however, does not allow incremental restoration of operating system files.

The advanced backup options give you additional backup choices. Descriptions of the options and information about setting them follows.

To set advanced backup options

  1. Open Backup, and then click Advanced Mode.

  2. In the Backup Utility dialog box, click the Backup tab, and then select the files and folders that you want to back up.

  3. Click Start Backup.

  4. In the Backup Job Information dialog box, click Advanced.

  5. Set the advanced backup options that you want, and then click OK.

The advanced backup options are described in Table 14-1.

Option

Description

Back up migrated Remote Storage data.

Backs up data that has been designated for Remote Storage. You can restore Remote Storage data only to an NTFS volume that is used with Windows 2000 and Windows XP Professional.

Note that Remote Storage is available only on Windows 2000 based computers.

Verify data after backup.

Verifies that the backed up data is exactly the same as the original data. This can substantially increase the time it takes to perform a backup.

Use hardware compression, if available.

Compresses the data that you are backing up so you can save more data on a tape. If this option is disabled, you do not have a tape drive on your computer or your tape drive cannot compress data.

Automatically back up system-protected files along with the System State.

Backs up all system files in your systemroot directory in addition to the boot files included with the System State data.

Disable volume shadow copy.

Allows you to disable volume shadow copy technology.
