如何在Python中进行数据可靠性传输和备份的最佳实践和技术选型

import socket# 创建TCP连接def create_connection(address):    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)    sock.connect(address)    return sock# 发送数据def send_data(sock, data):    sock.sendall(data.encode())# 接收数据def receive_data(sock, buffer_size=1024):    data = sock.recv(buffer_size)    return data.decode()# 关闭连接def close_connection(sock):    sock.close()

import hashlib# 计算数据的哈希值def calculate_hash(data):    md5 = hashlib.md5()    md5.update(data.encode())    return md5.hexdigest()# 校验数据的完整性def verify_data(data, hash_value):    if calculate_hash(data) == hash_value:        return True    else:        return False

import time# 发送数据，并确认接收def send_data(sock, data):    while True:        sock.sendall(data.encode())        response = sock.recv(1024).decode()        if response == 'ACK':            break        time.sleep(1)

from apscheduler.schedulers.background import BackgroundScheduler# 定义一个定期备份任务def backup_data():    # 备份数据的代码# 创建调度器scheduler = BackgroundScheduler()# 添加定期备份任务scheduler.add_job(backup_data, 'interval', hours=24)# 启动调度器scheduler.start()

import boto3# 创建S3客户端client = boto3.client('s3')# 上传备份文件到S3def upload_file(bucket_name, file_path):    client.upload_file(file_path, bucket_name, file_path.split('/')[-1])# 下载备份文件def download_file(bucket_name, file_name, save_path):    client.download_file(bucket_name, file_name, save_path)# 删除备份文件def delete_file(bucket_name, file_name):    client.delete_object(Bucket=bucket_name, Key=file_name)

import shutil# 执行增量备份def incremental_backup(source_folder, backup_folder):    shutil.copytree(source_folder, backup_folder, copy_function=shutil.copy2)
