Always set DHCP to give out the ERL for DNS.
set service dhcp-server shared-network-name LAN subnet 10.254.103.0/24 dns-server 10.254.103.1
Always set the ERL to look at itself for a DNS (127.0.0.1
set system name-server 127.0.0.1
Make sure that DNS is listening on your LAN ports.
set service dns forwarding listen-on eth1
set service dns forwarding listen-on eth1.2
Set DNS forward lookup to whatever.
set service dns forwarding name-server 10.254.103.4 # my Pi-Hole
set service dns forwarding name-server 220.127.116.11
If oyu are on a domain, tell EdgeOS to forward those to the DC.
set service dns forwarding options server=/ad.domain.com/10.254.0.21
set service dns forwarding options server=/domain.local/10.254.0.21
set service dns forwarding options server=/domain/10.254.0.21
Set up your static DNS entries.
set system static-host-mapping host-name nas inet 10.254.103.7
When we start looking, we'll start with the usual culprits like Veeam. ShadowProtect comes highly recommended to me by several folks (Including the guy who just built the ReadyNAS)... We'd hit the other major players as well.
So cost is going to bite you in the ass, since you said there were concerns about licensing. But they are all valid options.
We don't care if it's full install, agent based, or Hypervisor based. It just needs to work.
Based on this I would think Agent based would be a decent option. But didn't you say you have something along the lines of 300 VMs? Might become tedious.
Yeah, we'd likely do the dedupe at the Storage layer. Our Current Nimble devices do this relatively well with our live data. Something like 1.3 or 1.4 to 1 compression is what i remember. It may be more or less.
If we went Agent based, we can push the agents via PDQ Deploy for Windows and a shell script or something for Linux. (Most of our Production Linux systems are SLES 12)... If reboots are required, systems can be rebooted during our patch window... (5-7am every day).
Those little Atom processors that they tend to use (I miss the Sparc32 days, it was just more interesting) use very little electrical power and produce very little heat and tend to last for forever. Pretty much unbeatable.
@scottalanmiller Seagate surprised me with what a POS their NAS offering is. Not at all happy with it.
Drive makers don't make the best storage appliances. Just doesn't go together. Their interest is in selling drives. WD does a little better, but it is a weak offering too. It's RAID 5 only so that you have to buy super expensive RE drives.
