[PVE-User] pve-zsync issues

[Miguel González]

Hi,

  I have two servers running proxmox 5.3-6. Both run several VMs and I
am using pve-zsync to sync two machines in server1 in server two for
disaster recovery and offline backups.

  This has been working without issue with two proxmox servers running
5.1-46. I have just replaced them with two new servers.

  I have two jobs, one is reporting that is has to send the full batch
and the other one reporting a failure. Snapshots in the backup server
show  0B.

  root at server1:~# pve-zsync status

Nigthly jobs report different things:

cpanel1 VM:

and it has two set the full two disks, which I don´t understand why

plesk1 VM:
