Limit backup speeds
-
Is there a way to limit backup speed for specific delta backup jobs? I'm facing a bottleneck issue and so, until we fix new hardware, I need to limit the transfer speed of the backup jobs.
Currently I put a QoS limit on the XOA vm through xcp-ng center, but is there a better way? Ideally, only specific backup jobs should be limited.

That's the first time we have this kind of request. I would say it's not a bad idea
IDK how it's doable in XO code, but worth an issue on XO github tracker!In the mean time, QoS on the VIF is indeed a nice workaround.

One problem with limiting XOA VM is that the user interface might be slow if the backups saturate the vif. One possible solution is to have two vif on the XOA vm, one for storage transfers and one for the management interface. Not sure if this is possible though.

Yes it's possible: if your remote is on a network accessible fro VIF 1, then the connection to the host via VIF 0, it means it will go through like the way you want.
Please create the issue on XO GH repo, so our devs could take a look if it's doable -

@S-Pam Having a VIF for management and one for storage-traffic is a good solution, we do it that way to avoid crippling management during backups.
