Virtualization Redemption?
-
We COULD use a tool like RSYNC to do a delta transfer of full backups. But that is only efficient if the backups append nearly always, not if the data is changing all over the image. We want something with the rough equivalent of change-block tracking. That's where the Veeam, Unitrends, StorageCraft or even DRBD Proxy solutions come in, they all talk to the underlying storage and can do deltas in a way that RSYNC can't do given that we are talking about enormous filesystem images.
So I think that RSYNC becomes useless here, sadly.

Veeam Backup Essentials Standard is $899 per 2 sockets. Sold in 2 socket packs. I have never seen it sold in any other fashion.
So basically $2700 in this scenario. That adds up quickly.
Why would you need it for the third box? should only need it for the two local ones.

If you need a file level incrementals what OS is the client using on the VM? Can you use a local client like Storagecraft?
Yeah, you are missing the point. He is not doing anything with the OS. All full backup solution for VMWare/Hyper-V have ways to push only the delta/incremental since the last backup. This has nothing to do with the OS. It is all VM level.

Did not realize that the restore machine would not need it, but makes sense. Jared cleared that up for me.

I would reconfirm that with Veeam if @hubtechagain goes that route. I ended up not using the 3 host scenario. But it does make sense and the sale rep was upfront on that device not needing the license.

we have any veeam representation here?

We do but they have not been very active lately

Wait... what if we are over thinking this... What about Replication? HOST1 Replicates to HOST_DR every xx minutes?
That way only the changes replicate?

OMG, dose of reality time!! You are so right. Talking ESXi blinded us to the most obvious answer!

Pretty sure that HyperV does what is needed, for free, completely included and we just overlooked it. Doh!
-
Note: HOST2 could also replicate to HOST_DR... 8-)

Alternatively if you have any extra hardware to run you can look into any of these.
Open Source Storage: 49 Tools for Backup and Recovery
Using for a much smaller amount, we use Create Synchronicity for our mobile users.
It works well enough.
For this Amanda might be what you need.

Here are the heavier details on HyperV Replication from Technet. Pretty sure you can choose Azure as the DR too, if you wanted.
-
Also... more thinking out loud... Doesn't XenServer have replication options like that as well?

That's what DRBD Proxy is. They've had it long before HyperV did, but it is less than trivial to set up.

I was thinking more along the lines of like Hyper-V's replication... not the DRBD / HA setup.

Okay, so it's possible we have reached a free (other than my time) means of accomplishing this goal. yes?
I can do all of this on site so tell me if i'm off base or not.
-
setup new DR server with 2 new drives and reconfigure to raid 6
-
Setup Hyperv12 on DR server
-
P2V current VMs to DR host temporarily
-
HV 2012 on two "main site" servers
-
Migrate servers to their respective hosts
-
Setup Replication locally before shipping server to datacenter
-
Ship DR server to datacenter
-
Allow replication to do its thing?
-
-
@hubtechagain That sounds about right. You should note that the replication is not real time and happens on a set schedule (not sure what the lower limit is), so there could be a potential for data loss of XX minutes between the time HOST1 dies and its last replication to HOST_DR.
I would also dare suggest that Replication is not a replacement for backups. 8-)

from TechNet
Replication frequency—In Windows Server 2012 replication occurs every 5 minutes. In Windows Server 2012 R2, you can configure the replication frequency every 30 seconds, 5 minutes, or 15 minutes.That being said, this server will only ever be used if we have a complete physical failure at our main location. this is EXACTLY what i was looking for @dafyre you get atleast 100 nuggets.
