Backup and Recovery Goals

So it has to go to a local storage first, then to tape.
Kind of what I was reading, just putting thoughts out there.
But if that's the case, you only need enough storage to stage the data, 8 or so TB, not the full 24 GB you've been looking at.

I still question the need for two production servers. You have a 1 day RTO, doubling the cost of your production servers seems like an over spend to me. The only gain you get is if you have a server failure. But you have the additional cooling/heating costs, power costs, possible 10 GigE ports costs, etc.

This is a very important consideration. Going to dual servers is a big expense.
Yeah I've tried explaining that as well. Because hosting the second server off-site really doesn't appear to be an option from the conversations I've had so far. Having two only provide protection in the aforementioned scenario.
A power outage would still result in an outage. And its more to try and protect.

Is that still the case? If you use incremental replication, can you do it? Have you discovered your daily deltas yet?
Maybe StorageCraft can tell you what your deltas are? If your deltas are only a few gigs, you could go for nightly replication assuming you have that 30 Mb pipe you mentioned before.

but if you're a 1 site location and power goes out..... power is out. get a generator? regardless of server location, unless you use RDS or have an alt location, you'd be down down down until power comes up.

So are you saying, if you are planning for a power outage, make sure you know the whole plan, and if you even care if the server is working considering the rest of the business?

Yes, although if doing that normally you will use the disk as a point for restore too, makes things much faster.

So I found a rather easy way to find our delta for last week. 12.52 GB. Which isn't that much. Pushed out hourly to an online storage service could be reasonable.
Now to find options..

But do you need a second server at all?
-
The boss just told me to look at the Bronze and Copper options. So that kind of removes the available funds for a second server.

I'm not sure that I understand the metallic reference.

Cadellac vs a Honda options

Oh okay, I thought maybe but wasn't sure if that was what you meant.
-
A single server and tape backup for offsite might REALLY make sense. Unless you have a full secondary site to fail to and deep pockets, this is how SMBs generally run.
OR backup to cloud or similar instead of tape. You can play with that a little bit.
-
Obviously Porsche would be the Gold option, and Ferrari would be the Platinum option.
-
You have a bit of old equipment that should be able to be reused here.
Again, back to my suggestion:
1 new server for all production workloads1 local onsite backup server (running StorageCraft) - maybe a new to you/used box if current hardware won't work
1 offsite at your remote location replicated with the StorageCraft box - use currently owned hardware

Now to find options..
12.52 GB = 100.16 Gb = 100,160 Mb Assuming the 30 Mb/s connection mentioned earlier (and that you can use the whole thing) = 3338.7 seconds = 55.64 Mins
OK not bad, takes about 1 hour a day at full saturation to push that to your remote site. As you said, if you do that hourly, you should be fine.
-
Alright @scottalanmiller, Dustin seems to really want his full backups. Am I crazy to think they really aren't needed considering he has a StorageCraft backup solution?
I know this is a point of difference of opinion between Dustin and I.

Which can be done at night. Kick it off two hours after people have gone home and you are good to go.

Weekly fulls? No, not needed.

@Dashrender and @scottalanmiller how should I backup my VM's then? What is the restore process for if a VM takes a dive and I have no full to recover from?
The backup process has to remain someone current.
