A PowerShell module with nearly 700 commands for automating SQL Server administration, migrations, and backup testing.
dbatools is a PowerShell module that provides nearly 700 commands for automating SQL Server administration tasks. It solves the problem of manual, error-prone database operations by enabling automated migrations, backup testing, and multi-server management through a consistent command-line interface. The tool dramatically reduces the time and risk associated with traditional SQL Server administration methods.
Database administrators and DevOps engineers managing SQL Server environments who need to automate migrations, backup verification, and routine administrative tasks across multiple instances.
Developers choose dbatools because it replaces days of manual work with minutes of automation, offers comprehensive coverage of SQL Server versions (2000-2022), and provides a consistent PowerShell interface for both on-premises and cloud SQL environments. Its extensive command library and active community support make it the de facto standard for SQL Server automation.
🚀 SQL Server automation and instance migrations have never been safer, faster or freer

With nearly 700 commands covering migrations, backups, monitoring, and discovery, dbatools replaces manual tasks like instance migration in minutes instead of days, as demonstrated in the common use cases.
Commands are compatible with SQL Server 2000 through 2022, plus Azure SQL variants, though support varies, enabling automation across legacy and modern environments without rewriting scripts.
Works on Windows, Linux, and macOS with PowerShell Core 7.4+, allowing DBAs to use consistent automation tools in heterogeneous server environments, despite some command limitations.
Can migrate terabyte databases in under an hour and test 1000+ backups per hour, as highlighted in the performance section, making it suitable for large-scale enterprise operations.
On Linux and macOS, only 78% of commands work, and features requiring SQL WMI or -ComputerName parameters are unsupported, limiting functionality for non-Windows admins.
Requires multiple ports (e.g., 1433, 5985/5986, 135, 445) to be accessible, which can be a firewall and security headache in locked-down environments, as noted in the system requirements.
Can clash with Azure PowerShell or SqlServer modules, necessitating specific import orders or conflict avoidance modes, adding complexity to script maintenance and debugging.
Only 40% of commands work with Azure SQL Database, and 60% with Azure SQL Managed Instance, making it less comprehensive for cloud-native SQL management compared to on-premises.
