      Hello,

      I tried to Backup a VM with BackupNG. Sometimes it worked successfully to backup the VMs with the Deltabackup. But most times the backups failed. So I downlaoded the Log file and there I found an URL to that showed me this Error. I found something in the Internet, that says it is an Database error from Xenserver. But I don't know how to fix it.

      Hopefully someone coud help me.
      Thanks for your respons

      Regards,

      Linus

        Hi,

        We lack a lot of info to help you:

        1. What's your XenServer version? Is it up to date?
        2. The exact error message from the backup log
        3. Are you running XOA or Xen Orchestra from the sources? Is it up to date? if from the sources, did you followed the official doc instructions or a 3rd party script?

            I see "product_brand": "XCP-ng" in the log file, so are you sure it's XenServer?

            Double check both XS/XCP-ng and XOA are fully up-to-date.

            Anyway, this error is coming from the host, not Xen Orchestra: something is wrong within your host while attempting to do a delta operation. You can also try to restart the toolstack and see if the problem is fixed.

              Sorry, yes we use XCP-NG with the Version 7.6. So I try to restart the Host and after that I will do some Updates.

                Good, keep us posted. Also, as you have Pro support, you could create a ticket in your support zone: there is a response time guarantee that you haven't in the forum 😉

                  We could fix the problem. We had a full log partition on our xen host. This coused the problems with the backups. I hope this information helps you.
