This is beyond the scope of Bacula. Basically, use Corosync/Pacemaker (see http://www.clusterlabs.org/) to setup NAS as a high availability cluster service with NAS1 and NAS2 as the cluster nodes. The DRBD storage, bacula-fd, and a virtual IP address will be under cluster control, meaning all will run on only one server at a time and the IP is only assigned to one server at a time. Alternatively, setup a single virtual machine on the DRBD storage that also runs bacula-fd, then use Corosync/Pacemaker to run the VM on only one node at a time. Either way, it just looks like a single NAS box with a single IP address to Bacula and doesn't require anything fancy from Bacula. ------------------------------------------------------------------------------ How fast is your code? 3 out of 4 devs don\\\'t know how their code performs in production.
