三、功能特点
多数据库支持：SQL Server、MySQL、PostgreSQL、Oracle
定时备份：支持每天、每周、每月定时执行
邮件通知：备份完成后自动发送邮件通知
备份清理：自动清理超过保留天数的旧备份
日志记录：详细记录所有操作和错误信息
任务管理：添加、编辑、删除、启用/禁用备份任务
手动备份：支持随时手动执行备份
连接测试：测试数据库连接是否正常
配置持久化：备份任务配置自动保存
四、使用说明
4.1 快速开始
- 运行程序，点击"添加任务"
- 填写数据库连接信息
- 设置备份路径和计划
- 点击"确定"保存任务
- 任务将按计划自动执行
4.2 配置邮件通知
- 在任务配置中勾选"发送邮件通知"
- 填写收件人邮箱
- 修改
EmailNotifier.cs中的 SMTP 服务器配置
4.3 手动执行备份
- 在主界面选择要执行的任务
- 点击"立即备份"按钮
- 查看备份结果
4.4 注意事项
- 确保数据库服务正常运行
- 确保备份路径有写入权限
- MySQL 需要安装 mysqldump 工具
- 建议使用专用备份账户，权限最小化
