To prevent disk space from filling up
Navigate to Basic Settings > Management > Disk space fill up prevention.
Set the limit of maximum disk utilization in percents in the respective field. When disk space is used above the set limit, SSB disconnects all clients. The default value is 90, and you can set values between 1-99.
Optional step: Enable the Automatically start archiving option to automatically start all configured archiving/cleanup jobs when disk usage goes over the limit.
If there is no archiving policy set, enabling this option will not trigger automatic archiving.
