Hello Samuel, I'd try the following. (Apologies, I did not have time to test it, so it might contain minor mistakes.) <appender name="bitranlog" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <param name="ActiveFile" value="bitran.log" /> <param name="FileNamePattern" value="bitran.%i.log" /> <param name="MinIndex" value="1" /> <param name="MaxIndex" value="3" /> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedRollingPolicy"> <param name="MaxFileSize" value="5MB" /> </triggeringPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <param name="pattern" value="%-4relative [%thread] %-5level %class - %msg%n" /> </layout> </appender> The TimeBasedRollingPolicy based example that you would usually want to use in real life (instead of the above) is less verbose, and just as powerful. <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <param name="FileNamePattern" value="foo_%d{yyyy-MM}.log".zip /> <param name="ActiveFileName" value="foo.log" /> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <param name="Pattern" value="%-4relative [%thread] %-5level %class - %msg%n" /> </layout> </appender> You might also want to have a look at the javadocs. http://logback.qos.ch/apidocs/ch/qos/logback/core/rolling/SizeBasedTriggerin... http://logback.qos.ch/apidocs/ch/qos/logback/core/rolling/FixedWindowRolling... http://logback.qos.ch/apidocs/ch/qos/logback/core/rolling/TimeBasedRollingPo...

Hi, using this it is now complaining about a triggeringpolicy.
