Problem conclusion

  • The problem was that changing the option SKIPNTSECURITYCRC from
    NO (which is the default) to YES results in a full backup of the
    data (including files not changed at all).
      It is important to note that
        (a) the problem occurs one time only;
        (b) reverting back to SKIPNTSECURITYCRC NO does not cause a
    full.
    These problem has been fixed so changing the option
    SKIPNTSECURITYCRC from NO to YES doesn't lead to the backup of
    unchanged objects.
