Plutonium

https://buyvm.net/
Best DDoS protection for COD servers
30$ - 6 servers
45$ - 10 servers

No it's not your provider, no you can't protect your server with a firewall app or iptables
Your ip is public and extremely easy to find, without a scrubbing center you will not be able to defend against botnet attacks (which is what you're getting)

There is just a lot of DDoS happening to pluto cuz they dont do much to help owners

add me Kiels for more info

Oh, I see, I think I understand the process now. I thought I needed to make a copy of the server folder. This information will also help me save disk space. Thanks for the help!
