Multiple log files

Each time OH is restarted the log files openhab.log and events.log are copied.
Is it possible to turn this off?

I think they are not copied but rotated which means the oldest one is removed all other ones are renamed and a new one is created.
This can be configured see e.g. xml - log4j2 - limiting the number of log files - Stack Overflow

You are right they are renamed.
Is there no easier way off limiting the number of log files?
