Hi
and a happy new year to all of you! i hope you all enjoyed the christmas days and had a fine party at the turn of the year.

i hope you can give me a idea of how to use the backup in a cluster configuration.

well i have a cluster with one master and actually two nodes (the nodes will increase in near future)

at the master, there's only a local storage of 200 GB, the nodes have 2 Tb each (local)

Also i use a netapp wich i mounted using iscsi and LVM.This is a 4 TB storage and i use the normal network, not an extra one for iscsi!

My question is: what is the best configuration to backup the vms on the nodes?

PLAN A:
install the VM's on the NetApp Storage and make the backup on the free Diskspace of the local node, which runs the vm

PLAN B:
install the VM's local on the specific node which should run the VM and use the NetApp as Backup storage ( this seems not to work, because i cannot tell the LVM Volume to be a backup storage).

And at the end a last question from what i have tested so far:

I installed a vm locally on a node. then i went to the webinterface of the master and created a local backup storage using the local storage (200 GB) and made a backup job.
is there a possibillity to add the localstorage of a node too? Or is the only possibillity to make a nfs share on the node to integrate this storage?
