一、
随着信息技术的快速发展，数据库在各个领域扮演着越来越重要的角色。SQLite 作为一款轻量级的数据库，以其小巧、高效、易于使用等特点，在嵌入式系统和移动应用中得到了广泛应用。在实际应用中，数据库的备份、恢复以及恢复点错误处理是数据库管理员必须面对的问题。本文将详细介绍如何使用代码实现 SQLite 数据库的备份、恢复以及恢复点错误处理。
二、SQLite 数据库备份
1. 备份方法
SQLite 数据库的备份可以通过复制数据库文件来实现。以下是使用 Python 代码实现 SQLite 数据库备份的示例：
```python
import shutil
import sqlite3
def backup_db(source_db, backup_db):
try:
shutil.copyfile(source_db, backup_db)
print("备份成功！")
except Exception as e:
print("备份失败：", e)
使用示例
source_db = 'example.db'
backup_db = 'example_backup.db'
backup_db_path = '/path/to/backup/dir'
backup_db = f'{backup_db_path}/{backup_db}'
backup_db = backup_db.replace('', '/')
backup_db = backup_db.replace('/', '')
backup_db = backup_db.replace(':', '')
backup_db = backup_db.replace('', '')
backup_db = backup_db.replace('?', '')
backup_db = backup_db.replace('"', '"')
backup_db = backup_db.replace('<', '<')
backup_db = backup_db.replace('>', '>')
backup_db = backup_db.replace('|', '|')
backup_db = backup_db.replace('/', '/')
backup_db = backup_db.replace('', '\')
backup_db = backup_db.replace(' ', ' ')
backup_db = backup_db.replace('', '')
backup_db = backup_db.replace('r', 'r')
backup_db = backup_db.replace('t', 't')
backup_db = backup_db.replace('\', '\')
backup_db = backup_db.replace('\', '\')
backup_db = backup_db.replace('\', '\')
