MySqlBackup.Net.DevartExpress 2.7.1

MySqlBackup.NET

A versatile tool for backing up and restoring MySQL databases in C#, VB.NET, and ASP.NET.

Latest Release: v2.7.1 (May 11, 2026)
Change Log

Overview

MySqlBackup.NET is a .NET library (DLL) designed to backup and restore MySQL databases. Compatible with multiple MySQL connectors—MySql.Data.DLL, MySqlConnector.DLL, and Devart.Express.MySql.DLL—it offers a programmatic alternative to tools like MySqlDump, providing greater control and flexibility in .NET environments.

Developed in C#, this library supports any .NET language (e.g., VB.NET, F#) and excels in scenarios where MySqlDump.exe or MySQL Workbench are impractical, such as web-based applications (ASP.NET) or end-user tools with simplified interfaces.

Key Features

• Backup and restore MySQL databases programmatically.
• Supports all .NET languages.
• Export/import via files or MemoryStream.
• Conditional row exports (filter tables/rows).
• Progress reporting for export and import tasks.
• Flexible row export modes: INSERT, INSERT IGNORE, REPLACE, ON DUPLICATE KEY UPDATE, UPDATE.
• Ideal for ASP.NET and web service integration.

using MySql.Data.MySqlClient;

// For dotConnect for MySQL by Devart
using Devart.Data.MySql;

Backup a Database

string constr = "server=localhost;user=root;pwd=1234;database=test1;convertzerodatetime=true;";
string filePath = @"C:\backup.sql";

using (MySqlConnection conn = new MySqlConnection(constr))
{
 using (MySqlCommand cmd = conn.CreateCommand())
 {
 using (MySqlBackup mb = new MySqlBackup(cmd))
 {
 conn.Open();
 mb.ExportToFile(filePath);
 }
 }
}

Restore a Database

string constr = "server=localhost;user=root;pwd=1234;database=test1;convertzerodatetime=true;";
string filePath = @"C:\backup.sql";

using (MySqlConnection conn = new MySqlConnection(constr))
{
 using (MySqlCommand cmd = conn.CreateCommand())
 {
 using (MySqlBackup mb = new MySqlBackup(cmd))
 {
 conn.Open();
 mb.ImportFromFile(filePath);
 }
 }
}

Why MySqlBackup.NET?

Unlike MySQL Workbench (developer-focused) or MySqlDump.exe (restricted in web environments), MySqlBackup.NET offers:

• End-User Simplicity: Preset parameters for a one-click backup experience.
• Web Compatibility: Runs seamlessly in ASP.NET, bypassing hosting restrictions on executables.
• Programmatic Control: Fine-tuned output handling within .NET.

Dependencies

MySqlBackup.NET requires one of these MySQL connectors:

Compatibility

We aim for MySqlBackup.NET to achieve 100% SQL compliance, ensuring seamless compatibility with mysqldump and mysql.exe for both backup and restore operations. Version 2.6 introduces key improvements, addressing some flaws in previous version and compatibility challenges with mysqldump-generated files. If you encounter any incompatibilities, we welcome feedback via GitHub Issues to help us refine and uphold this goal.

Configuration Tips

Unicode Support

• Always use the default character set of utf8mb4, or utf8 in older MySQL versions that do not support utf8mb4.
• It is recommended to use convertzerodatetime=true in the connection string for compatibility when handling null datetime values.
