Hrotkó Gábor commented on LBCORE-146:
-------------------------------------

with 1.0.0 and this config:

<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>../logs/mylog.log</file>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>${TIMESTAMP} [%thread] %level %logger.%method:%line - %msg%n</pattern>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>../logs/mylog.%d{yyyy-MM-dd}.%i.gz</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>50MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>61</maxHistory> <!-- ~2 months -->
        </rollingPolicy>
    </appender>

it works!
