APAR status

• Closed as program error.

Error description

• Incremental forever backups of Microsoft Hyper-V virtual
  machines might be corrupted. The problem is due to a logic error
  in the Tivoli Storage Manager backup-archive client (data mover)
  code that identifies changed sectors. No error messages are
  logged during affected backup operations. However the affected
  backup data is incomplete and thus corrupted. Restore operations
  for the corrupted backup data are also reported as successful.
  No error messages are logged.
  
  The problem is not detectable until the restored data is
  accessed, either from a fully restored system or from a snapshot
  mounted by the Recovery Agent. Possible symptoms include:
  
  * One or more files might not contain the expected content
  * Operating system messages indicate file system corruption
  * Other erratic operating system or application behavior
  
  Portions of the corrupted Hyper-V backups might be recoverable.
  For example, it might be possible to use the Recovery Agent to
  recover certain needed files provided that those files were not
  affected by the incorrect backup data. It is not possible to
  determine in advance whether a given file in a Hyper-V virtual
  machine backup is affected.
  
  Note: The external symptoms are similar to those of APAR
  IT04831. However this APAR (IT05734) has a different root cause.
  
  Affected product versions: Tivoli Storage Manager for Virtual
  Environments: Data Protection for Microsoft Hyper-V 7.1.1 when
  using Tivoli Storage Manager Backup-Archive Client version
  7.1.1.0 or 7.1.1.1 as the data mover.

Problem conclusion

• The 7.1.1 Tivoli Storage Manager for Virtual Environments: Data
  Protection for Microsoft Hyper-V package has been updated at the
  7.1.1.2 level to include the fixing 7.1.1.2 data mover level
  needed for APAR IT05734
  (http://www.ibm.com/support/docview.wss?uid=swg1IT05734).
  Please see this flash:
  http://www.ibm.com/support/docview.wss?uid=swg21687942.
  IBM instructs customers not to run incremental forever backups
  of Microsoft Hyper-V virtual machines with the TSM 7.1.1.0 or
  7.1.1.1 data movers. Instead, use 7.1.1.2 or higher.
  
  Note: The 7.1.1.2 version of the data mover is only available in
  the 7.1.1.2 Data Protection for Microsoft Hyper-V package. It is
  not available as a stand-alone Tivoli Storage Manager
  Backup-Archive client download. However, because maintenance is
  cumulative, new versions (higher than 7.1.1.2) of the data mover
  that are made available for stand-alone download will also
  include the fixes for the problems described in the above flash.
