How to use Python to implement the data backup and restore function of the CMS system

Introduction:
With the widespread application of CMS (content management system), the data backup and restore function has become one of the important requirements. In the event of system failure, data loss or damage, timely backup and restoration of data can ensure system stability and data reliability. This article will introduce how to use Python to implement the data backup and restore function of the CMS system to help developers better protect and manage system data.

1. Implementation of backup function

1. Import necessary libraries and modules

import shutil
import os
import datetime

2. Define backup function

def backup_database():

# 获取当前时间
current_time = datetime.datetime.now().strftime("%Y%m%d%H%M%S")
# 备份数据库文件
shutil.copy2("database.db", f"backup/database_{current_time}.db")

3. Execute backup function

backup_database()

2. Implementation of the restore function

1. Define the restore function

def restore_database(backup_file):

# 判断备份文件是否存在
if os.path.exists(backup_file):
    # 备份当前数据库文件
    shutil.copy2("database.db", "backup/database_backup.db")
    # 还原数据库文件
    shutil.copy2(backup_file, "database.db")
    print("数据还原成功！")
else:
    print("备份文件不存在！")

2. Perform restore Function

backup_file = input("Please enter the path of the backup file to be restored:")
restore_database(backup_file)

3. Improve the function

1. Back up multiple files and directories

Back up multiple files and directories

def backup_files(dir_list):

current_time = datetime.datetime.now().strftime("%Y%m%d%H%M%S")
backup_dir = f"backup/backup_{current_time}"
os.makedirs(backup_dir)
for src_dir in dir_list:
    if os.path.exists(src_dir):
        dst_dir = os.path.join(backup_dir, os.path.basename(src_dir))
        shutil.copytree(src_dir, dst_dir)
    else:
        print(f"{src_dir} 不存在！")

2. Execute backup function

backup_files(["images/", "documents/"])

4. Summary

Through Python's shutil library and datetime module, we can easily implement CMS System data backup and restore function. Through the backup function and restore function, we can quickly back up and restore database files to ensure the security and reliability of system data. At the same time, we can also expand the function to realize the backup of multiple files and directories. Through the code examples in this article, I hope it can help you better protect and manage the data of the CMS system.
