Why the status of plugin which was not backed up last time is displayed in dashboard e-mail?
Dashboard e-mail shows the last status of each backup plugin. So if you for example did a backup of MSSQL some time ago or within initial backup, that was either successfully completed or interrupted by your request, the status ‘Completed’ or ‘Interrupted’ will be displayed in every dashboard e-mail, even if no more backups sessions of MSSQL were made.
