MS SQL Server for Toniq Database

Toniq uses Microsoft’s SQL Server software for database management, which improves database stability.  Express versions of MS SQL are acceptable (within Microsoft limitations such as database size).

The same version of SQL Server must be installed on at least one other computer as a backup server.

The Version of SQL Server must be MS SQL Server 2016 SP1 or newer

For any new installs, we recommend using MS SQL Server Express 2025

If your database is approaching 10Gb and you are not yet on SQL Server Express 2025 you will need to upgrade, and if your database is approaching 50GB you will require a paid version of MS SQL Server.

Talk to Toniq Support about your options.

Note for IT administrators

If a temporary server needs to be set up where the existing server will be returned without any major changes and there is no backup server with the same version of SQL installed we recommend installing the same version as the server being temporarily decommissioned.

Advanced setup

For larger organisations, SQL Server can be configured to connect to an instance of SQL on a different machine, such as in a data centre.

In these cases, due to permission restrictions, Toniq may not be able to perform backups. It is anticipated that your organisation has its own backup systems in place.
