Error description

  • Error Description:
    When trying to restore an encrypted VSS backup by using the IBM
    Spectrum Protect for Mail, Data Protection for MS Exchange or
    the IBM Spectrum Protect for Databases, Data Protection for MS
    SQL  "restorefiles" command,  if the ENCRYPTKEY option is set to
    SAVE (which is not a recommended value for Data Protection for
    SQL and Exchange operations) and the encryption key is not
    currently stored in the registry,  it may fail with error
    "ANS1235E (RC-1)   An unknown system error has occurred from
    which TSM cannot recover."

Local fix

  • Use the ENCRYPTKEY value that is recommended by Data Protection
    User's guides, i.e. GENERATE
    
    or
    
    Use the Backup/Archive client to GUI to access the restore data,
    which will prompt for the encryption key.  Enter the encryption
    key value so that it will be saved in the window?s registry.
    Thereafter the Data Protection restorefiles command should be
    able to process successfully.

Problem conclusion

  • This is a limitation of the current implementation. The
    workaround is to use the backup-archive client to back up a
    small file using the ENCRYPTKEY SAVE and INCLUDE.ENCRYPT options
    and the node name and encryption key of the Data Protection node
    whose data you are restoring. This will save the encryption
    password key in the registry in encrypted form. Then try the
    Data Protection application restore operation again.
