[SAC] New Backup Machine Configuration

Feedback from OSUOSL:

So we have 2 options:
1. We can add it to ganeti, migrate the existing backup VM over then
grow it's dick.
2. We can just have them install the main OS and give us access to setup
bacula however we want. I do not know if there are any permissions
restrictions at this level.

Long term option 1 means we can use the machine in other ways besides
backups later on, not that we would, or as a failover for replicating
some live machines on osgeo3 and osgeo4 (not a bad idea).

Any opinions.

Only thing I have down is the initial OS will use MD to create a
software RAID 5 spanning all 4 disks.

Thanks,
Alex
