Event ID 18 — Backup Operations

Updated: January 27, 2011

Applies To: Windows Server 2008 R2

red

You can use the Windows Server Backup snap-in or the wbadmin command to create and manage backups to protect your operating system, volumes, files, and application data. Backups can be saved to single or multiple disks, DVDs, removable media, or remote shared folders. They can also be scheduled to run automatically or manually.

However, system state backup is only available for the command line and is not available in the Windows Server Backup snap-in user interface. Also, you cannot configure a scheduled backup to create system state backups—but you can script the wbadmin start systemstatebackup command to run backups on a schedule.

In addition, you can use the Local Group Policy Editor snap-in (Gpedit.msc) to allow or disallow certain types of backups or backup locations. Policy settings for Windows Server Backup are located at: Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\Backup\Server.

Resolve

Reconfigure scheduled backup

To reconfigure a scheduled backup, you should perform the following general steps:

  1. Disable any scheduled backup that you have already configured.
  2. Configure a new scheduled backup.

Warning: The following resolution steps will cause you to lose any data that is present on the disk that you are going to use to store your backups because the disk will be reformatted. If you experience this issue, but cannot reformat the backup storage disk because it contains other scheduled or one-time backups, call Microsoft product support to determine if there are ways to preserve the backups. For example, you may be able to create a backup of the backup storage location itself, although this is not a supported scenario. 

To create or modify a scheduled backup, you must have membership in Administrators, or you must have been delegated the appropriate authority.

Disable a scheduled backup

To disable a scheduled backup:

  1. Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. At the prompt, type: wbadmin disable backup.

Create a scheduled backup

To create a scheduled backup:

  1. Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. At the prompt, type: wbadmin enable backup. Use parameters, as needed. (To view the parameters and help for this command, at a command line, type: wbadmin start backup /?).

    For example, to create a backup that will:

    • Schedule backups of hard disk drives e:, d:\mountpoint, and \\?\Volume{cc566d14-44a0-11d9-9d93-806e6f6e6963}\
    • Save the files to the disk DiskID
    • Run the backups daily at 9:00 A.M. and 6:00 P.M.

    Type: wbadmin enable backup -addtarget:<DiskID> -schedule:09:00,18:00 -include:e:,d:\mountpoint,\\?\Volume{cc566d14-44a0-11d9-9d93-806e6f6e6963}\.

Note: Reconfiguring a scheduled backup will reformat the backup storage disk and any old backups will be lost.

Verify

To verify that backup operations are running, or will run, successfully, you should do one or more of the following, as needed:

  • For any backup operations that you have run, look for Event ID 4, which indicates that the operation completed successfully with no errors.
  • Verify that no other backup or recovery operations are running so that you can start an operation.
  • Verify that you have enabled a scheduled backup, and is configured correctly.
  • Verify that the location where you plan to store your backups is available and online.

To perform these procedures, you must have membership in Backup Operators or Administrators, or you must have been delegated the appropriate authority.

Verify the backup completed with no errors

To verify that a backup operation completed with no errors:

  1. Open Event Viewer. Click Start, click Administrative Tools, and then click Event Viewer.
  2. In the left pane, double-click Applications and Service Logs, double-click Microsoft, double-click Windows, double-click Backup, and then click Operational.
  3. In the Event ID column, look for event 4 
  4. For this event, confirm that the value in the Source column is Backup.

Verify another operation is not running

To verify that another backup or recovery operation is not running:

  1. Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. At the prompt, type: wbadmin get status.
  3. If the command output indicates that no operation is running, then you can start a backup.

Verify scheduled backup is enabled

To verify that a scheduled backup is enabled:

  1. Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. At the prompt, type: wbadmin enable backup.
  3. If the command output shows a schedule, then a scheduled backup is enabled.
  4. Confirm that the schedule contains the correct parameters.

Verify storage location is online

To verify that a disk used to store backups is online:

  1. For the computer that contains the storage disk, open Disk Management. Click Start, click Run, and then type: diskmgmt.msc.
  2. Click View, click Top, and then click Disk List.
  3. For the disk that contains the volume that you will use to store backups, confirm that the value in the Status column is Online.
