I am using "SizeAndTimeBasedRolling" policy. 
where below are the values
<maxFileSize>100MB</maxFileSize>
<maxHistory>4</maxHistory>
<totalSizeCap>500MB</totalSizeCap>

It works perfectly when I have 4 files size 100 of same day.
It also works perfectly for 4 days history. 
but it does not remove old file from past date when the over folder size exceed from 500MB.

attaching logback.xml file.
