Event ID 658 — Backup Set Integrity

  • Articolo

Applies To: Windows Server 2008 R2

When you run a backup operation, Windows Server Backup runs checks for consistency and hardware and software corruption to determine the integrity of the backup set.

Event Details

Product: Windows Operating System
ID: 658
Source: Microsoft-Windows-Backup
Version: 6.1
Symbolic Name: ADMIN_PROTECTED_VOLUME_MISSING_EVENT
Message: A volume '%1' included for backup is missing. This could be because the volume is dismounted, reformatted or disk is detached. Please correct the issue and rerun backup.

Resolve

Bring missing volume online or delete from backup set

When you run a backup operation, Windows Server Backup checks that all volumes that are configured to be backed up are available. If a volume that is part of the backup set is not available, the operation will complete, but with errors. To resolve this issue, follow these general steps:

  1. Check that the disk that contains the volume or volumes specified in the event details is online. If it is not, then bring it online.
  2. Or, if the volume is not available anymore and you do not want to include it in the backup set, modify the scheduled backups and remove the volume from the list of volumes selected for backup.
  3. Re-run the backup.
  4. Check for Event ID 4, which indicates that the backup completed with no errors.

To modify a scheduled backup, you must have membership in Administrators, or you must have been delegated the appropriate authority. To perform a one-time backup or work with events, you must have membership in Backup Operators or Administrators, or you must have been delegated the appropriate authority.

Modify a scheduled backup to remove volumes

To update a backup schedule using the Windows Server Backup snap-in:

  1. Open the Windows Server Backup snap-in. Click Start, click Administrative Tools, and then click Windows Server Backup.

  2. In the Actions pane of the snap-in default page, under Windows Server Backup, click Backup Schedule. This opens the Backup Schedule Wizard.

  3. On the Scheduled backup settings page, click Modify Backup, and then click Next.

  4. On the Select backup type page, do one of the following, and then click Next:

    • Click Full Server to back up all volumes on the server. This is the recommended option.

    • Click Custom to back up just certain volumes, and then click Next. On the Select backup items page, select the check boxes for the volumes that you want to back up and clear the check boxes for the volumes that you want to exclude from the scheduled backup.

      Note: Volumes that contain operating system components are included in the backup by default and cannot be excluded.

  5. On the Specify backup time page, do one of the following, and then click Next:

    • Click Once a day, and then enter a new time to start running the daily backup.
    • Click More than once a day. Then, to select a start time, under Available time, click the time that you want the backup to start, and then click Add to move the time under Scheduled time. Under Scheduled time, click Remove to delete a time. Repeat for each start time that you want to add to or remove from the schedule.

  6. On the Add or remove backup disks page, do one of the following, and then click Next:

    • Click Do nothing.
    • Click Add more disks.
    • Click Remove current disks.

  7. If you choose to add more disks to store backups, do the following:

    • On the Select destination disk page, select the check box for the disk that you attached for this purpose, and then click Next.

      Note: By default, the likely disk or disks are shown in the list. These disks are external disks that can be used for moving backups offsite for disaster protection. If the disk that you want to use is not listed, click Show All Available Disks. Then, select the check box next to each disk that you want to use to store the automatic backups.

      A message informs you that the selected disk will be formatted and any existing data will be deleted. Click Yes.

    Important: Do not click Yes if you have data on the disk that you need. To use a different disk, click No, and then select a different disk under Available disks.

    • On the Label destination disk page, each disk that you selected is listed. A label that includes your user name, the current date, the current time, and a disk name is assigned to each disk. Click Next.

      Important: We recommend that you record and then physically attach the label information to each external disk. If you need to recover data from the backup stored on the disk, you will need this information to identify the disk.

  8. If you choose to remove disks, on the Remove current disks page, select the check box next to each disk that you want to remove from the disks used to store backups.

  9. On the Confirmation page, review the details, and then click Finish. The wizard modifies the schedule and formats any added disks.

  10. On the Summary page, click Close.

Create a one-time backup using the command line with no parameters

If you use wbadmin start backup with no parameters, the settings for your scheduled backup are used.

Make sure that the backup storage location specified by -backupTarget is online.

To perform a one-time 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 (no parameters): wbadmin start backup.

Confirm a backup completed with no errors

To confirm 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 the value in the Source column is Backup.

Verify

To verify that a backup set is complete and will be able to be used for recovery, you should do the following:

  • Verify that the backup operation to create the backup set completed with no errors.
  • Verify that the global catalog has information about the backup set.
  • Verify that the local catalog has information about the backup set.
  • Verify that the backup set itself is not corrupted by performing a recovery with the backup set.

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

Verify that a 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 the value in the Source column is Backup.

Verify the global catalog

To verify that the global catalog has information about the backup set:

  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 versions.
  3. If the command output shows information about backups, then the global catalog is intact.

Verify the local catalog

To verify that the local catalog has information about the backup set:

  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 versions -backuptarget:<VolumeName>.
  3. If backup versions are listed, then the local backup catalog is not corrupted and is intact. 

Verify that a backup works for recovery

To verify that a backup will work for recovery, you should try recovering something from the backup.

Note: Make sure that you do not mistakenly overwrite newer data. To avoid this, you can perform a recovery to a different volume than was backed up as part of the backup set. You will receive a message that any data on the destination volume will be lost when you perform the recovery. Make sure that the destination volume is empty or does not contain information that you will need later.

To perform a recovery:

  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 start recovery. Use parameters, as needed. (To view the parameters and help for this command, at a command line, type: wbadmin start recovery /?).

    For example, to run a recovery of the backup from March 1, 2005, taken at 9:00 A.M. of the d:\folder and its sub-folders, type: wbadmin start recovery -version:03/1/2005-09:00 -itemType:File -items:d:\folder -recursive.

  3. Review the items that you recovered to make sure that they were recovered as you expected.
