python3 多线程备份文件

import os
import shutil
import threading

def backup(src, dst):
    shutil.copy(src, dst)

# 原始文件路径
src = "/path/to/src/file"
# 备份目录路径
dst = "/path/to/backup/dir"

# 创建备份目录
if not os.path.exists(dst):
    os.makedirs(dst)

# 备份文件列表
files = [
    "file1.txt",
    "file2.txt",
    "file3.txt",
]

# 创建线程列表
threads = []
for f in files:
    src_file = os.path.join(src, f)
    dst_file = os.path.join(dst, f)
    thread = threading.Thread(target=backup, args=(src_file, dst_file))
    thread.start()
    threads.append(thread)

# 等待所有线程执行完成
for thread in threads:
    thread.join()

# 输出备份完成信息
print("备份完成")
