    Hello, Just a feedback. I am having trouble using CBT Backups with NBD. Host Details: XCP-NG Version : 8.3 latest (stable) Xen Orchestra: latest:stable (From Source) The first full backup always seems to work. The delta backup gives the error: 'HANDLE_INVALID' the writer IncrementalXapiWriter has failed the step writer.checkBaseVdis() with error HANDLE_INVALID(VBD, OpaqueRef:xxxxx). It won't be used anymore in this job execution. Start: 2026-08-09 14:01 End: 2026-08-09 14:01 Duration: a few seconds Error: HANDLE_INVALID(VBD, OpaqueRef:xxxxxx) This is a XenServer/XCP-ng error

    @gsszuber Hi, Yes indeed, you need to preserve the root of the bucket from Lifecycle. We just had a customer with a similar issue. Can you help us by giving a small screenshot of the field to filter out the root (or filter in the three folders) please?

    Just recieved another update from veeam... Regarding the general earlier errors: Warning : Failed to use CBT: [Task e75c4247-2ee1-7b51-088c-b970ace60f3d (Async.VDI.list_changed_blocks) failed: . SR_BACKEND_FAILURE_460. . Failed to calculate changed blocks for given VDIs. [opterr=Source and target VDI are unrelated] Our QA team did hear back from Vates support, who says its tied to a recent bug they've found with blktap calls: https://github.com/xapi-project/blktap/pull/444 Our QA engineer hasn't heard back yet on ETA when it will be pushed out in a general release yet though

    You already spotted this over on 12468, so this is just to close the loop here. That one's fixed: Pierre Brunet put the fix on a branch, @Andrew and @abudef both tested it, and it's merged now. Since you're running from source on master, you should be able to pull past that merge rather than wait for a release. One thing to keep in mind, though: the same error string showed up in 11875 for a completely different cause, so if it comes back after you update, it's probably not this bug again. I'd let 12468 be the thread to follow since that's where the people who fixed it are.

    @florent No explicit assigned migration or backup network set. Backups generate errors somewhat randomly. As one VM won't get the "error" one time. But on the next backup run it will. And the third time it might not. This even happens on VMs that are turned off, and therefore shouldn't have any changed bytes between backups. Host is reachable from XO Network has NBD enabled All VMs use VHD IPv4 Backup type is Delta

    @acebmxer we are far more explicit on the real usage of NBD, paing the way to mark a failed NBD connexion as an error in a few month also working on a diagnostic tool to be more efficient on the checks thank you all for your time

    @poddingue said: I haven't used that tab myself, and since it's built around VMs that do have backups, I don't know if it gives you the negative view you want. If it doesn't, https://feedback.vates.tech is where that gets counted. Maybe you can build some sort of filter but I don't think so. I'll use https://feedback.vates.tech for future suggestions. Tks

    XO 6.7.0 went out on 30 July, and the changelog carries Bastien's fix under Backups as "Fix failed status on successful retry", pointing at PR https://github.com/vatesfr/xen-orchestra/pull/10129 and back at this thread: https://xen-orchestra.com/blog/xen-orchestra-6-7/. Given what you said about keeping the backup XOA on a version you trust, I would not rush it, but that is the version to look for when you do move. I have not exercised the retry path myself, so if a retried VM still reports the job as failed after you upgrade, it is worth saying so here.
