logback rollingpolicy dont work (no backup file is created)

I try to use logback for a project and want to have a classic daily rollover. I cant make it work : all logs keep in the default file.

Either I badly understood the rolling policy, or it dont work corectly. In fact I thought that I I run for instance my tomcat one minute after the last log, the "current" log file is backed up in another file...

For test purpose I tried a "minutely" rollover. Someone see something horrible in my config ? :

<appender name="dailyRollingFileAppender"
    class="ch.qos.logback.core.rolling.RollingFileAppender">
    <File>C:/myProject/programs/apache-tomcat-8.0.21-presentation/logs/presentation-log.log
    </File>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- daily rollover -->
        <FileNamePattern>C:/myProject/programs/apache-tomcat-8.0.21-presentation/logs/presentation-log.%d{yyyy-MM-dd_HH-mm}.log</FileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy
            class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
        <!-- keep 1 day history -->
        <maxHistory>1</maxHistory>
        <cleanHistoryOnStart>true</cleanHistoryOnStart>
    </rollingPolicy>
    <encoder>
        <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{35} - %msg %n
        </Pattern>
    </encoder>
</appender>

Thanks!
