Hello,

I have a cluster with 2 nodes and every night I setup to make automatic backup on a server with FreeNas 8.0.4.
The backup hangs everytime and the log is bellow:

Why it hangs???
I have tested the network speed between proxmox cluster and NAS...It's very fast...
Is there any solution???
Thanks..
 
here is:

what i noticed that the backup process hangs hours on "INFO: adding '/mnt/vzsnap0/images/102/vm-102-disk-1.vmdk' to archive ('vm-disk-ide0.vmdk')" ..see the attached image

try lzo compression instead of gzip (lzo is much faster)
