Administrators may request if Archiver supports MySQL Databases instead of using MSSQL. This article provides a link to the system requirements.
Archiver currently only supports SQL databases hosted using Microsoft SQL Server.
Refer to the Software Requirements for Archiver. As noted only Microsoft SQL Server is listed as a supported SQL database type. Microsoft SQL Server Express is also compatible, but alternative SQL databases are not supported at this time.
