IT30814: INCORRECT OR VERY LARGE VALUE FOR TOTAL NUMBER OF BYTES INSPECTED FOR BACKUP ARCHIVE CLIENT BACKUP.

APAR status

• Closed as program error.

Error description

• When performing a backup with the IBM Spectrum Protect
  Backup/Archive client, the backup may show an
  exorbitant value for the "Total number of bytes inspected: ".
  For example, A 200GB filesysytem may
  show the inspected bytes as:
       Total number of bytes inspected:          1.39 PB
  Even though the Filesystem size remains consistent, the total
  bytes inspected can vary for each
  backup, possibly showing a value of 250TB instead of the 1.39PB
  in this example.
  Although this problem appears to be similar to APAR IT08013,
  regarding a large value for bytes inspected, this is a different
  issue that occurs due the manner in which the inspected files
  are calculated.
  The only way to identify this specific defect is with a client
  trace using "service, enter, debug", which would show the
  compare for 1 file, but the status processing for a different
  file; for example, notice that the comparison is performed for
  object "a1"
       28.10.2019 11:08:12.062 [016100] [17740] :
     ..\..\common\ba\incrdrv.cpp(12553): cmpVal 0 for \a1 vs. \a1
  at the same time the status was processed for object "a2":
      28.10.2019 11:08:12.062 [016100] [17740] :
     ..\..\common\ba\DccTaskletStatus.cpp(1094): Entering  -->
      DccTaskletStatus::ccMsgProcessed
      Processed   \\krjukov-a\d$\dir12\a2
  .
  IBM Spectrum Protect Versions Affected: All supported versions.
  .
  Initial Impact: Low
  Additional Keywords: TSM, baclient TS002550862
  

Local fix

• NONE.  The backup finishes successfully, only the displayed vale
  for Total number of bytes inspected statistics is incorrect.
