Limit backup speed including remotes

[David Thistlethwaite]

I need to limit the speed to of the backups so I will not saturate my networks both local and remote, anyone have any suggestions ?

Thanks

Hi David,
LAN:
i did this on my LAN with a second NIC inside PBS. that NIC is limited to 50mb/s (~500mbits)

WAN:
i did this on my VPN router by policing the traffic that destinated to the remote PBS. - i just put that traffic into a lower priority class.
if you have some Linux system as firewall you can use "tc" together with "iptables" to mark them (iltables) and then police them (tc).

incomplete example for iptables and TC to priotise traffic (i had NOT DONE this on a PBS or PVE but on a ordinary ubuntu linux system!):

Was this for a physical system or a VM.

And thank you for your insights
