I tested this now a bit more. And now it works with the traffic limiter.
Your last updates have optimised the backup system too much for my NFS storage
and with that froze somehow the timeout (XO is running on local storage).
And you are right it is doing it per VM, but i think this was in an older version the other way around (wich would be more important to me, but not for others ).
But it would be great if i could get somehow an evenly distribution of the full backups .
