Volume Shadow Copy初始化中InitializeForBackup函数问题

tabgift 2016-01-05 09:04:33
根据window提供的Volume Shadow Copy service API来实现快照功能,但是在初始化函数InitializeForBackup的时候,报错0x80042302。网上百度了说是服务没有启动,Volume Shadow Copy和Microsoft Software Shadow Copy Provider我已经启动并且重启,但是调用InitializeForBackup还是报上述的错误,请高手指点下,多谢

这个问题是由于64位的环境中运行32位程序引起。 在build的时候用64位生成。

没准是因为你的权限不够。 仅供参考:
bool AdjustPrivileges() {
    HANDLE hToken;
    TOKEN_PRIVILEGES tp;
    TOKEN_PRIVILEGES oldtp;
    DWORD dwSize=sizeof(TOKEN_PRIVILEGES);
    LUID luid;

    if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) {
        if (GetLastError()==ERROR_CALL_NOT_IMPLEMENTED) return true;
        else return false;
    }
    if (!LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &luid)) {
        CloseHandle(hToken);
        return false;
    }
    ZeroMemory(&tp, sizeof(tp));
    tp.PrivilegeCount=1;
    tp.Privileges[0].Luid=luid;
    tp.Privileges[0].Attributes=SE_PRIVILEGE_ENABLED;
    /* Adjust Token Privileges */
    if (!AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), &oldtp, &dwSize)) {
        CloseHandle(hToken);
        return false;
    }
    // close handles
    CloseHandle(hToken);
    return true;
}

InitializeForBackup Method of the IVssBackupComponents Interface The InitializeForBackup method initializes the backup components metadata in preparation for backup. HRESULT InitializeForBackup( [in] BSTR bstrXML ); Parameters bstrXML Optional. During imports of transported shadow copies, this parameter must be the original document generated when creating the saved shadow copy and saved using IVssBackupComponents::SaveAsXML. Return Value The following are the valid return codes for this method. Value Meaning S_OK Successfully initialized the specified document for backup. E_ACCESSDENIED The caller does not have sufficient backup privileges or is not an administrator. E_OUTOFMEMORY The caller is out of memory or other system resources. E_UNEXPECTED Unexpected error. The error code is logged in the error log file. For more information, see Event and Error Handling Under VSS. VSS_E_BAD_STATE The backup components object is not initialized, this method has been called during a restore operation, or this method has not been called within the correct sequence. VSS_E_INVALID_XML_DOCUMENT The XML document is not valid. Check the event log for details. For more information, see Event and Error Handling Under VSS. Remarks The XML document supplied to this method initializes the IVssBackupComponents object with metadata previously stored by a call to IVssBackupComponents::SaveAsXML. Users should not tamper with this metadata document. For more information on how to use InitializeForBackup with transportable shadow copies, see Importing Transportable Shadow Copied Volumes. Requirements Client Requires Windows Vista or Windows XP. Server Requires Windows Server 2008 or Windows Server 2003. Header Declared in VsBackup.h; include VsBackup.h, Vss.h, and VsWriter.h. Library Use VssApi.lib. See Also IVssBackupComponents IVssBackupComponents::SaveAsXML Send comments about this topic to Microsoft Build date: 8/15/2007
