Node is running on zfs storage (part of 3 node cluster) . I can backup successfully any VM with vma.zst (snapshot), but when I try to restore error appears. Already tried prelocation=off but with no success. Any ideas ?

No clue..... maybe some bug. Problem was on Proxmox V 7.4 and 8. As you can see speed limit wasn't so slow 5120000000000
