C++ 빅데이터 개발 시 데이터 백업 및 복구 문제를 어떻게 처리합니까?

#include <iostream>
#include <fstream>

using namespace std;

int main() {
    string inputFile = "data.txt"; // 原始数据文件
    string backupFile = "backup.txt"; // 备份文件

    ifstream fin(inputFile);
    ofstream fout(backupFile);

    if (fin && fout) {
        // 读取原始数据并写入备份文件
        string data;
        while (getline(fin, data)) {
            fout << data << endl;
        }

        cout << "数据备份成功！" << endl;
    } else {
        cout << "文件打开失败！" << endl;
    }

    fin.close();
    fout.close();

    return 0;
}
