Error description

• Client versions 7.1.6.5 and higher and 8.1 and higher for Apple
  Macintosh platform, can backup unchanged files and directories
  due to
  the "adu_ino" attribute incorrectly being handled.
  
  For example:
  
   macfilio.cpp  =========> Entering fioCmpAttribs()
  macfilio.cpp  fioCmpAttribs: skipACL:'0', skipACLUpdateCheck:'0'
  macfilio.cpp  fioCmpAttribs: ACLs compare to be equal
  fileio.cpp    fioCmpAttribs(): old attrib's data from build (IBM
  TSM
  8.1.0.2)
  macfilio.cpp  fioCmpAttribs: Attribute comparison of two files

  macfilio.cpp  Rsrc size               0          0 <---Same
  
  As can be seen the only attribute reported as different is
  "adu_ino", as previous stored size of the attribute is 0.
  
  The client has incorrectly truncated the previous size to 0 and
  sent to the server and when it compares it for the next
  backup, the size is seen as different than 0.
  
  
  Note: Also check APAR IT21322 which looks similar from the
  symptoms but is working as expected.

  Client 7.1.6.5 and higher, and 8.1.0 for Apple Macintosh

Problem conclusion

• Now during incremental backup the client backs up files only if
  their attributes change.
