Backup_agent trace log size control?

In my env, I setup a separate pod specifically to run backup_agent to do a continuous backup of the fdb cluster. One question I have is the trace log file size and rotation. Does the backup_agent like the fdbserver has a default 10Mib log size and only allow maximum 10 files? Or it allows for indefinite number of log files to be created? And is there a way to set the max number of log files and size when invoking the backup_agent?
