ボリュームのバックアップ方法を教えてもらえますか?
以下は私のコードです。C: ドライブのスナップショットを作成してバックアップを試み、CopyFile を使用してファイルごとにバックアップします。値をバックアップする方法はありますか?
cout<<"=============Begin Initialize=========="<<endl;
if(FAILED(CoInitializeEx(NULL,0)))
{
cout << "CoInitialize() failed\n";
return(0);
}
if(FAILED(CoInitializeSecurity(
NULL,
-1,
NULL,
NULL,
RPC_C_AUTHN_LEVEL_PKT_PRIVACY,
RPC_C_IMP_LEVEL_IDENTIFY,
NULL,
EOAC_NONE,
NULL)))

cout << "CoInitializeSecurity() failed\n";
return(0);
}
if(FAILED(CreateVssBackupComponents(&m_pVssObject)))
{
cout << "CreateVssBackupComponents() failed\n";
return(0);
}

return(0);
}
// if(FAILED(m_pVssObject->SetContext(dwContext)))
if(FAILED(m_pVssObject->SetContext(VSS_CTX_BACKUP | VSS_CTX_APP_ROLLBACK)))
