Veeam backup of PVE vm on spinning disks ceph issues

[squebel]

Hello, case 08166423 is open with Veeam support. We are running 12.3 and plugin version 1.5 and we have a couple of PVE clusters running Proxmox CEPH but using a hybrid setup with spinning disks. In some situations, the snapshot that Veeam is creating of that vm is causing major IO performance issues. I am being asked to immediately upgrade to the latest version hoping that it will fix the issue. Is there anything in the newer version and plugin that fundamentally changes the way a PVE vm backups are run?
