IC88272: TSM 6.4 CLIENT 'DSMC RESTORE IMAGE -INCREMENTAL' COMMAND DOES NOT WORK CORRECTLY ON A WINDOWS 2012 REFS FILESYSTEM

APAR status

• Closed as program error.

Error description

• The TSM 6.4 client supports Windows 2012, which introduced the
  ReFS filesystem. While the 6.4 client does support ReFS for
  most functions, there is an issue with a particular type
  of image restore.
  The command 'DSMC RESTORE IMAGE -INCREMENTAL' does not apply
  file system changes made after the image backup. Image restore
  of the ReFS volume completes successfully, but no file system
  changes made after the image backup are appliec.
  

Local fix

• Instead of doing restore image with the 'incremental' option,
  perform the operation in two steps:
  1- restore image
  2- restore changes
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Backup-archive client versions 6.3 and 6.4   *
  *                 running on Microsoft Windows 2012.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: See ERROR DESCRIPTION                   *
  ****************************************************************
  * RECOMMENDATION: Apply fixing level when available. This      *
  *                 problem is currently projected to be fixed   *
  *                 in levels 6.3.2 and 6.4.1. Note that this is *
  *                 subject to change at the discretion of IBM.  *
  ****************************************************************
  TSM Client does fail to correctly recognize the new file
  system ReFS. The file system was introduced in Windows 2012.
  The result of the incorrect ReFS identification is the failure
  to apply changes to a file system after image restore has been
  completed.
  

Problem conclusion

• TSM client file system identification code was updated to
  correctly identify ReFS. After this code change TSM Client
  successfully completes the "incremental" part of
  'restore image -incremental' command.
  

Temporary fix

• A fix for this problem is currently targeted for interim fix
  package 6.4.0.1. Until the interim fix is actually available
  this information is subject to change at the discretion of IBM.
