Resolve

Create a new backup

If the location that you use to store your backups is accidentally used for another purpose, all the backups that you have created can be deleted. If this happens, you should create a new backup and save it to a location that is dedicated to storing backups.

To create a one-time backup, you must have membership in Backup Operators or Administrators, or you must have been delegated the appropriate authority.

To create a new 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 start 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 be stored on drive f, of volumes e:, d:\mountpoint, and \\?\Volume{cc566d14-4410-11d9-9d93-806e6f6e6963}, type: wbadmin start backup -backupTarget:f: -include:e:,d:\mountpoint,\\?\Volume{cc566d14-44a0-11d9-9d93-806e6f6e6963}\.

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.
