Hello Alejandro,
every 15 mins or CA API Portal creates a new version of this file, as far as I know it is useless to keep old versions of this file. Because of this, after certain time, you will get disk full error even there is space in disk since all inodes in the system is consumed.
I also had the same issue and wrote a crontab task to remove these files older than 7 days. It did not cause any problems, but ask CA Support before deleting them.
Regards
