数据库备份工具

原理：在原生的docker镜像基础上，加入一备份工具，增强备份功能。 提供postgres, mysql5镜像，可直接使用，如有需要请提issues。

• 可以自行构建docker镜像，支持不同的数据库及不同的版本，如mysql8, oracle, sqlserver2017+等等
• 支持自定义命令
• 可以把备份后的文件存入另一台服务器
• 备份失败邮件通知
• 服务端每日10点检查上传的备份文件，如未检查到发邮件通知
• 每日凌晨自动备份
• 可设置备份文件最大保存天数(最少3天)
• 参考tls实现加密传输备份文件到服务端，rsa非对称交换密钥 + aes-256-gcm对称加密(每次随机密码+固定验证密码)

backup databases

Support all databases and the database images can be find in docker.

• Support for custom backup commands.
• Obsolete files will be deleted automatically.
• You can copy the backup files to another server.
• Send email when backup failed.
• The server checks the backup files that are not uploaded at 10 o'clock every day. If the backup files are not checked, an email notice will be sent
• Automatic backup in every night.
• The maximum number of days to save backup files can be set (at least 3 days).
• Reference to the TLS implementation of encryption transfer backup files to the server.
