NBD connection during backup
-
@manilx Tested putting XO on the Management network. Same result, backups do not use NBD...
-
Remove the "backup network" entry to leave it as default, check that XO is connected in Settings/server to that mgmt IP of the host and try again.

that looks similar my problem https://xcp-ng.org/forum/topic/8336/nbd-setup-no-such-item

@olivierlambert Did that. No change.

Maybe @florent will know

@olivierlambert Here are the respective screenshots:

@manilx Found it.
The backup I had was "backup" not "delta".
Choosing delta and Advanced settings I can turn on NBD:
Turned on and all is well. Sorry for the confusion. My bad.
Backup speed doubled.

Ahhh !! Great news
I missed it myself, so no worries. So you went from which speed to which? -
O olivierlambert marked this topic as a question on

@olivierlambert 50-80MB/s to up to 160/180
-
Nice speed increase! Probably also with less CPU load on the Dom0 at the same time
-
@olivierlambert Haven't checked the CPU as CPU is never a problem on my load
But yes this speed is a lot better so I can backup more frequently (every 2hrs for the important VM's)Actually the speed on my homelab is faster than the ones we get at the enterprise with "real" hardware.
