Error when trying to manually backup VM

[TheSover]

Hello!

I'm experiencing an issue when attempting to manually backup a VM. Whenever I try, I encounter the following error message:



This problem only occurs on some nodes, while automatic backups work correctly on all nodes.

Thank you!

i guess you're seeing this on a PVE node?

if yes, do the nodes have the same version? (you can check with 'pveversion -v' on each nodes cli for example)

Thank you for your response. I checked the versions on each node where the backups are working and the ones where they are not working and indeed the versions are different.

Not working:


Upgrading would fix it?

Upgrading would fix it?

yes because then the other node also knows the new options
