connectNbdClientIfPossible
yes connectNbdClientIfPossible is the nearest error message from the real cause
Now, why does it fails ?
nbd should be enabled on the network used for backups , do you have a default backup network defined ?
xo must have at least one VIF on this network
See post - https://xcp-ng.org/forum/post/104549 I do have backup network defined. I believe before doing the last round I did have NBD enabled at the pool level on the PIFs and the backup network defined. During trouble shooting it mentioned about NBD being the issue so i disabled NBD, I left the backup pool network defined. I send PM of chat working to the conclusion. Also i did re-add a vhd first SR and migrated the vm "Docker of Things" to that since that was one of the vms i was having constant issues with.
the last backups logs...

First success full with NBD disabled 2026-04-21T04_24_12.036Z - backup NG.txt
Just ran again this morning expected it to pass but 2 vms failed - 2026-04-21T10_10_14.175Z - backup NG.txt
With NBD disabled looks like the Host does the backup not xo itself...
