    @Danp I was going to do the upgrade over the December / January Christmas break in Australia but that is when this issue became apparent so we didn't want to be making major changes until it was resolved. I note @anthoineb noted the first report was late August / September 2025 which was just before 8.2.1 reached EOL, so it would be a shame not to have a fix for it tested on 8.2.1 as it seems an upgrade to 8.3 would be unwise while we still have this issue?

    @laszlobortel since we are generating the stream sequentially, we though that there wasn't any real world gain. Also, if my understanding is correct using one thread means we will have only one process( + xo + nbdkit-vddk) processes , and we were trying to limit the risk of zombie process locking the disks , which was far too common with the previous code we'll do a quick test to ensure it does not beak anything and propose either a better default of a configuration option note that this will be a concurrency per disk, so VM with a lot of disk will put more pressure on the source

    Hi @halvor, FYI, ACL V2 / RBAC is now available in the REST API. You can create a privilege that only give you read privilege on your host. You can see the RBAC doc. A dedicated thread is available on the forum thread, please feel free to share your feedback. Thank you.

    Continuous Replication -> SR Disk space

    Hi, There is different things one must consider during CR: SR type: block based or file based? First one will be thick provisioned, so plan a lot of space (eg: local LVM, LVM over iSCSI etc.). Local ext/XFS, NFS or XOSAN aren't affected by this problem Snapshot left: to do a delta, we must have a way to compare to something. The snapshot which left on the SR is the one that will be used for the next backup. It will be compared to the current disk state and only the delta will be sent. So that's perfectly normal "Job canceled to protect the VDI chain": this is a protection to avoid doing another backup while the previous removed snapshot isn't coalesced. You have a link in the message, please refer to the documentation for details

    Continuous Replication -> Exchange Log

    @mts said in Continuous Replication -> Exchange Log: If you use the native windows-backup or a third-party application it will delete the transaction-log after backup. How can I achieve the same with xen-orchestra? I'm running low on disk-space right now... I think that you confusing physical (layer) backup with logical backup. XOA can backup/replicate/snapshot phisical medium which is a hard disk presented to your VM. It has nothing to do with the data in the VM (logical layer).

    Hmm I think it might be possible using xe CLI and creating the drives manually (creating VBDs I suppose). I never spotted such a use case before, but again, might be doable It is using VNC (via noVNC in XO). You can copy a template, but a template is just a set of "configuration" for your VM (eg PV or HVM mode, some virtual BIOS settings).

    Hi, If you are using XOA, please create a support ticket. This way our teams could take a look remotely to find the best solution.

    Thanks for the tip. I was using node v8.11.4 and had issues compiling during the upgrade then upgraded to the latest stable node version which wasn't v8.x. I upgraded to v8.16.2 now and it runs fine. Thanks.

    Indeed, 6.2 uses a very old configuration for keyboard mapping and therefore doesn't work correctly with XO.

    I switched due to SSD replacement and XCP-ng new installation. I didn't think about that switching from ext3 to lvm does also have an effect from thin to thick provisioning Anyway I found the explaination, here -> "a snapshot on a LVM based SR will double the whole VM disk size!" But I will think about to switch to ext4 -> topic solved, thank you!!

    Change the remote in your job config. If you want to keep the previous backup there, just move or copy everything to the new remote.
