    @anthoineb in fix_records at line 105 you have is_a_snapshot for one case, and is-a-snapshot for an elif. Is the XML attribute formatted with dashes or underscores in the state.db? Or is it possible that records might exist with either format and this catches both potential cases? (I only have underscores in my /var/lib/xcp/state.db)

    @gcpeters4 said: @john.c This is a good idea as well. If the previous suggestion of trying to do a DNS round robin approach doesn't work, this may be my best option. Thanks for taking the time to provide your suggestion! By the way my suggestion is recommended best practice from Microsoft for their Active Directory software and/or technology. My suggestion will be more likely to work if your DNS servers and requests have issues with Round Robin configuration. Plus with my solution you can easily add more servers as domain controllers to the cluster, as required and use replication to keep them consistent and up to date.

    the last rewrite of the stream processing ( spring 2025 ) focused on stability and memory footprint, and , on a standard cpu, it tops at around 300MB/s per backup job. Your benchmarks are very interesting, and they confirm most of it. this limit was not really an issue since, in most case the xapi was limiting around 100MB/s per disk , but it will be more a more visible limit Note that master have some fixes on the memory usage (not related to backups) That's why we have started an internal workforce focused on performance, with all the teams from the kernel to the backups, including storage, network and xapi. If I can brag a little : [image: 1779106650898-afd7b59b-a4f0-4a92-88ee-2c7ba52d18bf-image.jpeg] i9 , nvme disk , backup to a nvme disk in passthrough, xoa and vm are on the same host, so it's quite far from real world data, but it shows where the limit is

    I also encountered this problem. If you are using Debian you can use pre-packaged XO from sources https://github.com/mathiswolff/xen-orchestra

    @olivierlambert I tested this now a bit more. And now it works with the traffic limiter. Your last updates have optimised the backup system too much for my NFS storage and with that froze somehow the timeout (XO is running on local storage). And you are right it is doing it per VM, but i think this was in an older version the other way around (wich would be more important to me, but not for others ). But it would be great if i could get somehow an evenly distribution of the full backups .

    You need to get the exact same structure ideally to not lose any data. But it's not a big deal, just copy/rsync whatever you like to the destination and that's it.

    Errors in CAPS means an error from the host. Check host logs, also check dynamic min memory == dynamic max

    Indeed, XO doc was built for XenServer (before XCP-ng existed). @Darkbeldin will update this accordingly

    Double check your 2nd host have permission to connect to the LUN. Try local commands on this host to see if you can access the LUN (iscsiadm for example).

    There's no XO tasks per se, so you can't see it What matters is you have all the VM migrated in the end, but yes, it's not "visible". Next major XO UI will have "XO tasks" that will display clearly the queue

    I got the same error again today. It's a delta job with two remotes. [image: 1617015537043-fe12531c-52e2-4457-bc13-ee36db7f4fb5-image.png] Even though it says the backup failed, it looks like it is available on both remotes: [image: 1617015649230-ca6eabb8-f810-44ac-bce0-7079755bc7de-image.png] srv01 = pool member srv02 = pool master srv03, srv04 = backup remotes XOA runs on srv02 The error seems to imply that it can't resolve the hostname of srv02, but that seems rather odd. I am using static IP only.
