Comments Off on WINDOWS SERVER 2003 SUPPORT COMING BACK TO DPM 2012 R2

As many pointed out 2003 Supported was removed in Data Protection Manager 2012 R2

Steve found a public annoucement that its on its way back

http://www.buchatech.com/2014/03/windows-server-2003-support-coming-back-to-dpm-2012-r2/

Hello Folks, I am the GPM for the DPM product group and sincerely apologize for this. Not supporting an already supported server OS for back-up is DPM 2012 R2 was a mistake. We are fixing this in the next update roll-up for DPM scheduled to be released shortly. Thanks for your patience.

This is good news as Data Protection Manager wont hold down a suite upgrade all the way around , ITS NOT A FREEE PASS to keep goofing around with 2003 servers , they are close to end of life , upgrade/migrate/power off but until you do at least we can soon again protect 2003 workloads with Data Protection Manager 2012 R2

Now go off and migrate Smiley

Changes in Hyper-V Backup in 2012 R2

Comments Off on Changes in Hyper-V Backup in 2012 R2

Aidan Finn pointed out in a recent post that there are changes in 2012 R2 Backup of Virtual Machines

http://www.aidanfinn.com/?p=15759 , as always its a good read

One change is that we rely on snapshots on the virtual machine what this looks like from a backup point of view

image

Create the Backup Job

image

Start the Backup

image

We can now see that a snapshot is being created will redirect write IO to the avhdx files

image

image

We can see the avhdx files created when the backup starts

image

image

And after the backup is complete the snapshot is being merged

image

Creating a additional backup

image

Repeats the pattern , shapshot backup cleanup

image

For recovery we can see the snapshots created during backup and a full recovery restores both vhdx and the xvhdx file

image

DPM == Sucess

image 

And when we start the recovered VM it merges the delta files , and we can start the VM again

VM was consistent and didnt show any unexepted shutdown error when restarted

DPM Virtual Machine Recovery Hyper-V Clustering

Comments Off on DPM Virtual Machine Recovery Hyper-V Clustering

One task needed for planning for disaster recovery with DPM is the naming of the VM from a clustering point of view.

If all VM’s are created through VMM then will be prefixed with SCVMM but in this example we have created one VM from Cluster Manager and one from VMM

The scenario for this type of recovery is a “dead” cluster or VM’s that was deleted by mistake.

Being able to recovery directly would be preferred but thats not currently a option

image

This leaves us with VMMTESTB prefixed from a naming point of view with SCMMM and one without when selecting the VM’s from DPM

image

And the view from Cluster Manager

image

And after creating the protection group we are ready to test a recovery

image

And our view from VMM

image

If we need to recover the VM to the orignal source we can just select recover

image

And we can recover to the original instance

image

And to provoke a error

image

We kill the VM from both cluster and hyper-v

image

If we then tries to recover a VM to its Original Instance

image

The recovery dies as we dont have the origianal VM

image

So we need to create a empty VM

image

Point it to a dummy location ,the name needs to match the original VM name

image

And no VHD attached

image

In VMM we can not see the new VMTESTA and the VMTESTA that we delted , this scenario is if the cluster dies and needs to be rebuild but VMM isnt “gone”

image

We can then restore the VM directly

image

We then have the temp clustered VM , we need to delete that

image

And also on the Hyper-V Host , this can also be done from VMM to avoid having to open the settings to find the restore VM

image

And Configure Role

image

And select Virtual Machine

image

And Enable it for HA

image

And last clean up if the VM wasnt deleted from VMM , remove the VM that have missing state

Protecting Windows 2003 Workload Hyper-V DPM 2012 R2

Comments Off on Protecting Windows 2003 Workload Hyper-V DPM 2012 R2

So far one of the big issues with Data Protection Manager 2012 R2 is the lack of support for Windows 2003 Workloads , Yes 2003 is close to slipping out of patching and support but NOT as of writing , so people still need to protect their workloads.

If people are still on 2003 there is a reason , ISV being annoying , workloads being retired and 100 different options so its critical that we are able to protect it.

So if you plan to upgrade to 2012 R2 consider the impact of the 2003 servers , either leave the 2003 workload on a downlevel DPM server , or plan to upgrade to use Hyper-V integration

image

Trying to add a older agent result in Error 307 and is unsupported.

image

And trying to browse the 2003 agent says the same , dont work and isnt supported

image

But through the Hyper-V integration we can select our 2003 VM and add it to a protection group

image

At least we can add the server to a protection group

image

And after a few minutes we can see the 2003 server being protected through the Hyper-V integration

image

And from a recovey point of view we recover the whole VM

image

And browse down though the VHD and select single files to recover.

So we can protect 2003 servers if the workload is on Hyper-V and we dont need transaction backup SQL/Sharepoint/Exchange.

So its better than nothing but not much , hopefully Microsoft will reverse on this and add 2003 support to Data Protection Manager 2012 R2

Data Protection Manager 2012 R2 Fiber Channel Tape Sharing with a side of Install Part 1

Categories: Data Protection Manager, DPM, Uncategorized, Windows Server 2012
Comments Off on Data Protection Manager 2012 R2 Fiber Channel Tape Sharing with a side of Install Part 1

This will be the posts focused on using Data Protection Manager with Tape Library Sharing

For Data Protection Manager to be able to use library sharing the Tape Library and the Backup Servers needs to be connected though Fiber Channel , no other data paths are supported

One other option is to use partitioning so one Library can be sliced up into mutiple devices , this will from a Data Protection Manager standpoint be treated as a standalone installation

The install here follow the reference documentation from http://technet.microsoft.com/en-us/library/hh758124.aspx but adding the steps to get the fabric configured

Call me old fashioned but i really still like Tape as long term retention , sharing the library will help keep cost down as we can use larger library

In this example we have 2 servers DPM01 and DPM02 , DPM01 will act as library server and DPM02 will act as library client.

Prereq : DPM01 and DPM02 are booting off the SAN in this example so their Alias and Zoning against the storage have already been completed

Image-40

The servers have no library or tapes connected

Image-41

From a Fabric point of view we login to our switch and create a “New Alias”

Image-42

To keep things simple we create a Alias called Tape

Image-43

On our list of world wide names we select the two tape drives in the library and “Add Member”
