ERROR: job failed with err -13 - Permission denied

[mhammett]

Googling shows that this error message when backing up is most often associated with LXC container permissions. While I do use LXC containers, this error appears to be exclusively on KVM\QEMU VMs. Some of them were freshly created on Proxmox, while others were migrated from VMWare. I am backing up to a PBS host and using local storage on that host. I do have VMs that were migrated that are backing up just fine. The backups start, but then fail part way through the transfer process.

Hi,
please upgrade to a current version, i.e. pve-qemu-kvm >= 9.0.0-2 and start your VM after installation to invoke the new binary, then you will get a more precise error message. Check also your system journal for any errors around the time of the issue. What does zpool status -v say?
