[GTALUG] On the subject of backups.

[Alvin Starr]

Sadly this one is a bit of a non-starter.

The client really only wants to use Centos/RHEL and ZFS is not part of 
that mix at the moment.

The data is actually sitting on a replicated Gluster cluster so trying 
to replace that with an HA NAS would start to get expensive if it were a 
commercial product.
