I'm sure I did a complete rebuild.

FWIW, I have also started having this same issue after updating to the latest sources.

Here are some details --

The backup breaks off at approx. 44-45% with the error mentioned above ...

If that should be a new thread just give a decision then I'll open a new one.

julien-f

@black_sam Please makes sure that you are using the latest xen-api lib. Also, this might be a XCP-ng/XenServer issues, please check your host's logs. Out of curiosity, are you using compression in your backup job?

Black_Sam

@julien-f

xcp-ng 8.2.0 is fully patched so ist should be up to date.
I didn't setup any compression options. I only configurated the backup jobs over xen orchestra

€dit:
hmmm... I think it was a problem with my network... after shifting the host into an other subnet without VLAN the backup finshed without any issue.

Thank you for your support

@black_sam Thanks for your feedback
