IBM Spectrum Protectâ„¢ client 7.1.3.x interim fix downloads
IBM Tivoli Storage Manager (TSM) client 6.3.2.x interim fix downloads - EOL

APAR status

• Closed as program error.

Error description

• During IBM Tivoli Storage Manager (TSM) backup or archive
  operations using client-side deduplication, if the
  operation fails with 'ANS1311E Server out of data storage
  space', under certain conditions the backup or archive of the
  next file will be reported as successful by the TSM client or
  TSM API, but
  the backup or archive copy of that file is incorrect.
  
  The restore of an affected backup or archive copy
  will fail with an error such as 'digest validation error',
  'unknown format', or a crash. The data that
  was intended to be backed up or archived in the copy being
  restored may not be recoverable.
  

Local fix

• Until you can apply a fixing level, use one of the following
  circumventions:
    1.use server-side deduplication instead of client-side
      deduplication
    2.turn off deduplication
