APAR status

  • Closed as documentation error.

Error description

  • The documentation needs clarification on how the compression
    feature is applied when selected for the backups (for example
    in conjunction with sub-file or email backups).
    
    Tivoli Storage Manager Versions Affected:
    IBM Tivoli Storage Manager FastBack for Workstations 6.3.x and
    7.1.x on Windows
    
    Initial Impact: Low
    
    Additional Keywords: Spectrum Protect encryption compression
    email backup replication sub-file bitmap
    

Local fix

  • 1. For files defined as eligible for continuous backups and
    scheduled backups :
        If both compression and sub-file copy are enabled, then the
    files that are smaller than the sub-file copy limit will be
    backed up compressed and the files that exceed this limit will
    be backed up using sub-file copy (not compressed). If only
    compression is enabled, the same rule applies knowing that the
    default sub-file limit is then set to 1 TB.
    2. For files defined as eligible for email backups (specified
    in the 'Email Application list' field) :
    These files are backed up using email bitmap backup which
    doesn't have any tunable limit on file size, i.e. all specified
    files are backed up using this feature disregarding their size.
    Therefore, compression is not used for these files.
    

Problem summary

  •  Compression feature need clarification
    

Problem conclusion

  •  ID updated documentation for the 8.1 release
