IC92873: SOME EXECUTABLE FILES FOR WINDOWS SERVICES NOT BACKED UP ON WINDOWS 8 AND WINDOWS SERVER 2012

IBM Tivoli Storage Manager (TSM) Client 6.3.2 Downloads and READMEs

APAR status

• Closed as program error.

Error description

• Some executable files (xxxxxxxx.exe) for Windows NT style
  services are excluded from backup. This can impact system
  restores such that certain applications or services will not
  start.
  
  Beginning with Microsoft Windows Vista and Microsoft Windows
  Server 2008, executables for Windows NT style services are
  treated as part of the VSS System Writer portion of system
  state. Thus the Tivoli Storage Manager backup-archive client
  backs up these files as part of system state and omits them from
  other file system backup operations.
  
  Beginning with Microsoft Windows 8 and Microsoft Windows Server
  2012, these executable files remain a part of the VSS System
  Writer, but are not considered to be part of the recoverable
  system state. Therefore the correct behavior for Tivoli Storage
  Manager is to include these files during file system incremental
  backup but not during system state backup.
  
  For example, if the Tivoli Storage Manager Backup-Archive Client
  scheduler service is installed on Windows Vista, Windows 7,
  Windows 8, Windows Server 2008, Windows Server 2008 R2, or
  Windows Server 2012, then the executable file for the scheduler
  service (dsmcsvc.exe) is treated as part of the VSS System
  Writer. However, it is only treated as part of recoverable
  system state on Windows Vista, Windows 7, Windows Server 2008,
  and Windows Server 2008 R2. dsmcsvc.exe should not be treated as
  part of recoverable system state on Windows 8 and Windows 2012.
  
  The following table summarizes the correct behaviors for backup
  of these executable files:
  
  Table 1:
  
                          PART OF         BACKED UP AS PART OF
   OPERATING SYSTEM    SYSTEM WRITER   SYSTEM STATE   FILE SYSTEM
   ----------------    -------------   ------------   -----------
   Windows Vista            Yes            Yes            No
   Windows 7                Yes            Yes            No
   Windows 8                Yes            No             Yes
   Windows Server 2008      Yes            Yes            No
   Windows Server 2008 R2   Yes            Yes            No
   Windows Server 2012      Yes            No             Yes
  
  The following table summarizes the problem behavior for these
  executable files on the affected operating systems:
  
  Table 2:
  
                          PART OF         BACKED UP AS PART OF
   OPERATING SYSTEM    SYSTEM WRITER   SYSTEM STATE   FILE SYSTEM
   ----------------    -------------   ------------   -----------
   Windows 8                Yes            No             No
   Windows Server 2012      Yes            No             No
  
  The Backup-Archive Client behavior should be corrected so that
  these executable files are backup up as part of the file system
  backup operations as shown in Table 1 above.
  
  Tivoli Storage Manager Versions Affected:
  Tivoli Storage Manager client versions 6.3.1.x (x >= 1) and
  6.4.0.x (x >= 1) on Windows 8 and Windows Server 2012
  
  Note: Support for Windows 8 and Windows Server 2012 was
  added as of versions 6.3.1.0 and 6.4.0.0.
  
  Initial Impact:
  Medium

Local fix

• Downgrade client code to 6.4.0.0
  or make a copy of missing executables to a new path and
  backup/archive client filesystem backup will back them up
  under the secondary path
  
  or if on version 6.3.1.x;
  
  Downgrade client code to 6.3.1.0
  or make a copy of missing executables to a new path and
  backup/archive client filesystem backup will back them up
  under the secondary path

Problem conclusion

• The TSM include-exclude list has been changed in order not to
  exclude the NT services from local drive backup.
  

Temporary fix

• Interim fix level 6.4.0.11 includes a fix for this problem.
