I see that fleecing is available from PVE 8.2, I will enable it next week once all the nodes will be upgraded to the latest version. Thanks for the suggestion. In the meantime I found this thread on the forum: https://forum.proxmox.com/threads/high-io-wait-during-backups-after-upgrading-to-proxmox-7.113790/ which mention the max_workers parameter. I change it to 4 for the next scheduled backup and see if there are some improvements (I migrated the affected VMs to catch the new configuration). I will keep you posted!
