@florent One last update. I reverted to Master branch (6699b) yesterday evening and the backup ran without issues overnight.

@TeddyAstie Thanks for the update. I do actually have a VBIOS for that GPU, but I wasn't entirely sure what to do with it - is there a process to inject it? I've found resources for Proxmox and others, but I really like XCP and equally I don't want to migrate my entire setup just for that. If it's really tricky then I'm not too worried about it, as I say the VM actually runs the cameras perfectly fine on CPU alone, it's negligible. Edit: Looks like this post might answer my question: https://github.com/xcp-ng/xcp/issues/786 "Even when specifying romfile and rombar properties on the xen-pci-passthrough device in QEMU, the ROM region is not mapped into guest memory." timemaster5 created this issue in xcp-ng/xcp open PCI ROM BAR not exposed to guest when using xen-pci-passthrough #786

502 is an answer coming from your S3, telling the server is having an issue. Adding @florent in the loop

I've had a lot of updates happening in the homelab. I've replaced the T620 with an R740, expanded my storage for both HDD and NVME pools. Also did a little min-maxing on the hardware to help separate traffic, decrease some latency and jitter for internet traffic and introducing IDS There are a lot of additions and modifications, but I guess the other big one is setting up a Dell Precision 5820 with XCP-NG as a studio and prototyping rig. Replaced Ansible with AWX, added some more VMs and migrated others but in all that I've updated the diagrams as well! Will say that XCP-NG offers up the flexibility and performance that I've needed so far. Would love to try out the XOSTOR storage at some point but will have to move around my entire setup haha.

I looked into the backup job and i forgot to enable a few settings when recreated the backup job. After renabling the below settings i reran the backup job. The vm in question did a full backup. All passed.
