Hi. vzdump creates tar archive with zero filled files on a nfs storage. It was working few a pair of weeks ago, but after some time it started to behave like this. Backup to a local storage is ok. The only thing I remember was changed is the pve-kernel.

NFS export
Code: 
/srv/data/backup/proxmox 10.0.1.251(rw,no_root_squash)

NFS mount
Code: 
storage:/srv/data/backup/proxmox on /mnt/pve/storage type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.0.0.11,mountvers=3,mountport=43618,mountproto=udp,local_lock=none,addr=10.0.0.11)

NFS storage (archive file size: 2MB)
Code:
