/usr/local/CyberCP/tmp - Safe to delete?

I have tons of files and a lot storage being used in /usr/local/CyberCP/tmp

I’m assuming it’s safe to delete everything in there, as it looks like most of those files are from last year… I am guessing they are made for backup but never deleted for some incomprehensible reason?

I think it is safe, it is failed backup files. For me it deletes automatically, probably something is wrong with your cronjob, check for crontab logs for errors.
