proxmox backup slowed down VMs

[powersupport]

HI,

Our proxmox server is connected to a backup server via a public network, may I check if it will causes VMs to over use of bandwidth? or it will not affected vm bandwidth

Thank you

hi,

not super clear what you mean here. What is meant with "causes VMs to over use of bandwidth? " are you talking about the configured bandwidth of the vm network adapter?

Yes, talking about the configured bandwidth of the vm network adapter @dcsapak

generally no, the backup bandwidth does not go over the virtual nics, so they shouldn't influence it, BUT if both are over the same network they of course are limited by the remaining network/physical hardware
