Managing the size of the log database

SES Evolution uses an administration database and a log database. Depending on the configuration of your security policies and the desired amount of logs, the volume of the log database may grow quickly and reach a critical threshold. Logs are kept by default for 12 months on SQL Server Enterprise, and two months on SQL Server Express. You can customize this value, either when installing SES Evolution or via the administration console.

Logs that are too old are deleted daily at midnight by a task that runs on the backend.
