Error description

  • After completing restore backupset by the following command for
    example,
    # dsmc restore backupset /source_filespace/
    /destination_directory/ -backupsetname=backupset_name
    modification timestamp (mtime) of a restored directory in
    destination_directory might be set to the different timestamp
    from the original one in source_filespace.  The mtime might be
    changed to new timestamp when child objects under the directory
    were just restored.
    This symptom might occur only when the parent directory and
    child objects were restored in the following order:
    Restoring /parent -> /parent/child/file -> /parent/child/
    It is expected that modification timestamp (mtime) of the
    parent directory is also restored as it is in source_filespace.
    IBM Spectrum Protect Versions Affected:
    Tivoli Storage Manager and IBM Spectrum Protect Client all
    supported versions on all supported platform
    Initial Impact:
    Low
    

Local fix

  • None. It can be safely ignored because no data is corrupted but
    only mtime of the restored directory might be set to new
    timestamp.
