I purchased a server in OVH for backup my server in other provider, im doing the backup via rsync and for some reason i get massive mails none stop of "DDOS ATTACK MITIGATION" for the rsync =/
So i cant find OVH trusted to backup with his filter? or there a way around?
Any advises

rsync via direct ip of the server? if yes, do a VPN, and backup thru the vpn.
Setup wireguard and pump your data.
What u guys suggest is an hassle @host_c @Levi .
I tought there were a way to disable this "anti DDOS" that i dont know of.
I guess i look for another provider.
@OVH_Matt please adjust your DDOS Protection system it triggered to easly even on not harmful proccesses as rsync
@FlorinMarian , please buy this server from OP @Advicerxyz , it has good DDoS protection it appears
Thanks but see my last comment in the other thread.
lol it seems the rsync of transfering mass files trigger OVH DDOS protection prob because of massive packets size changes.
I change inc backup in jetbackup to compressed seems to run for now smoothly.
Or do a VPN, as that will compress/organise packets and not trigger the alarm.
This is much more likely to trigger DDoS protection, as OVH will see a stream of unknown UDP packets, much more similar to a DDoS, than an rsync which simply uses a regular SSH TCP connection.
As for why even rsync is detected as DDoS, I am not sure, and this has never happened to me at OVH.
One workaround would be to transfer via IPv6, as they don't have DDoS protection on v6, or it is not nearly as strict. That is if you want to look for workarounds and already write off the possibility of contacting support and having them solve the actual issue to begin with (which might be reasonable tbh).
^ this or set SSH compression toggle in rsync
Just tar.gz each account and db and transfer did not trigger the DDOS Protection, if you rsync the files via SSH for some reason it triger TCP ACK
Contact OVH support. They can adjust their filters. In this forum no one will help you.
Are we all going to pretend like he didn’t already solve it?
I guess allowing certain ip's via firwall bypasses the firewall for eg
allow the server you're taking backup from in ovh firewall.
