Backing up clustered storage volume

Hello,

I am looking at an alternative to my DPM setup in a DR situation. What I am aiming for is if our server room burns down I have placed another physical server in a secure room with 20tb of storage that I hope to hold copy's of the clustered storage folders.

The way our environment is setup is as follows:

2 x Dell PowerEdge servers running Win2k8 R2 64bit with Hyper-V Clustering
1 x Dell Dell PowerVault MD3200i via SCSI (SAS) interface

What I have done is created a 3TB LUN shared between the 2 cluster hosts that the vhd/avhd files sit on and run the virtual machines. All I want to be able to do is take a straight copy without turning any of the VM's off over a weekend and dump them to a seperate, independent NAS server that is sitting in the same building but in a secure locked room.

My reasoning behind this is that if the room burns down, I can go to the 20tb NAS, copy the VHD files off, setup the clustering services again (if need be) and get essential services back online. The connectivity I am using to the NAS is 2 x 1GB NIC's and the test copy's of larger files are running great and will successfully copy over a weekend period without network saturation.

The products I have used currently are as follows:

NAS: Open-E DSS v7 Operating system which I have successfully integrated with our active directory and setup secure directory for the files to be dumped to.

Cluster Servers: I found an app called ViceVersa Pro that can organise copys of files on a schedule, email me log files on fail/completion. I have used the option 'Use Shadow Copy Service' to copy open files however, I cannot seem to enable Shadow Copy Services on the Clustered Share Volume on either server.

This application copys unopen files fine, but when it hits a file that is in use, it fails. I understand why, so if I could work out how to enable Shadow Copys on the Clustered Storage Volume I would be out of trouble. It seems all apps who claim to copy open files use the shadow copys service so I am kind of stuck.

If I am going down the wrong route with this solution please point me into the right direction, but this is what I have deemed to be the easiest solution so far.

Regards,

Josh

As I use Zfs for my San, I snapshot/send at the San level. However before that i used veeam and that works great for your type of setup. Not cheap though

You will need a backup product that understands CSV. Backing up running VMs requires coordination among all of the Hyper-V hosts, which is a non-trivial task.

If you upgrade your hosts to Hyper-V Server 2012 (free) or Windows 2012, there is a new feature that allows you to replicate the VMs to another cluster.

Thank you for the responses guys that has made a few things clear to me.

kevinhsieh, when you say backup to another cluster, is there any wiggle room to replicate to network storage rather than another cluster volume?

You need to replicate to another server, i believe. That server can be attached to the storage. If you have storage and no server, how do you plan to recover?
