Hi,
We have got a DPM 2012R2 running on Windows Server 2012R2.
Amongst other things this DPM backs up a Hyper-V 2012R providing sevearl VMs.
The guest OS of one new VM is Windows Server 2016.
So, is it supported to do a Host-level backup of the Windows Server 2016VM running on Hyper-V 2012R2 with DPM2012R2?
Thanks in advance!
Source info would be nice aswell.
regards

Hi
I am using DPM 2016 and one of the servers it is going to protect is a Windows 2016 server with Hyper-V, formatted using ReFS. Firstly I want to double check this is supported by DPM 2016 (the DPM support matrix does not explicitly say it supports protecting ReFS volumes, only that it doesn't support it on Exchange servers), and, secondly, if one of the VMs is an Exchange server with NTFS, is that supported even though the Hyper-V host uses ReFS?
Thanks

We have recently built a new Windows Server 2012 Hyper-V Cluster and are using DPM 2012 SP1 to protect the VMs. I noticed that even after deleting VMs from the Cluster and DPM, they are still showing as a Recovery Destination in DPM when I go to recover a server. This is a problem as these are not valid recovery destinations.
I noticed these servers are listed in the DPM SQL DB table tbl_AM_Server.
I tried to run the Remove-ProductionServer.ps1 but this gives errors and does not work.
They should have been automatically cleaned out by DPM (I would think) but this has not happened.
Any help would be greatly appreciated. I have looked high and low for a solution.

I have two datacenters and 3 Hyper-V hosts. I have 1 DPM server in each location.
Workloads are live on Hyper-V 1 in Site 1.
Hyper-V 2 hosts only replicas in Site 1.
Hyper-V 3 hosts tertiary replicas in Site 2.
DPM 1 backs up Exchange/SQL from live workloads.
DPM 2 provides secondary protection for Exchange/SQL in Site 2.
DPM 1 backs up VMs with short retention from Hyper-V 2.
DPM 2 should backup Hyper-V replicas on Hyper-V 3 but when I modify the protection group I get Error 152 like this: https://social.technet.microsoft.com/Forums/lync/en-US/ceb036f8-27f0-4f93-b1d8-a94d58fb5320/scdpm-2012-r2-dpm-error-id-152-source-cannot-be-added-to-the-protection-group-because-of-existing?forum=dpmsetup
I had no problem creating the protection groups this way and never had to deal with any nonsense about switched protection. Now, with one update or another this is all busted. Is DPM incapable of this now and is it simpler to move to Altaro for my VM protection or is there a fix available that I don't have to create a support call to get?

Hello,
We have DPM 2016 and Hyper-V 2016 Cluster.
We have some VMs with large .vhdx, but we want to exclude them from being taking during VM backup of Hyper-V Cluster.
We have tried using the registry Setting on Host HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup
But it did not work.

Any help would be more appreciated.

Hi
We have MABS installed and use it to back up our VMs at the host level.
This is working fine for all VMs except for one.
The error it gives is:
"
"
I've looked up this error, and suggestions are to run DiskShadow /L c:\temp\output.txt
list writers
exit
And examine the output.txt file for '\\' which should lead to any invalid image names that need correcting.
I've tried this on the VM and the Hyper-V host that it is on, however there is nothing in the output.txt files that need fixing.
I've tried the following troubleshooting:
Backups in MABS at the guest level for 'All Volumes' and 'System Protection' work fine for the VM.
I've made sure that there are no space-related issues on the DPM storage pool. I have disabled protection of the VM that used Storage Disk 1 on the NAS, removed the current replication data and have enabled protection again for the VM this time specifiyng Storage Disk 2 on the NAS,
Tried a consistency check and it failed again, this time with a different error.
I throttle all machines to 85% as recommended and ran the consistency check again - which failed with the same error.
Fyi, it does back up some of the VM because it says it transferred 160 GB. Again OS level backups for the contents of the VM is working, it's just when trying to back it up at the host level that it fails.
'VSSAdmin List Writers' on the affected VM showed no VSS errors.
Any ideas?
Guest OS: Server 2016
Hyper-V Host OS: Server 2012 R2
DPM Version: 2016
One of our VMs started acting a little crazy after Hyper-V role was removed and it was rebooted.
Attempts to re-add the Hyper-V role fails, giving an error about the CPU not supporting it.
DPM refuses to load on the VM.
How do I fix this?
Do I have to move it to a Hyper-V 2016 host, add the Hyper-V role, and move it back??
The idea of moving it back seems risky.
Please help.
On windows 7 machine after turning on NX in BIOS and turning on "Data Execution Prevention" option per below link the laptop failed to boot up. It is asking for Bitlocker key which is lost.
Can you revert back to "Last Good Configuration" or is there any option left to boot up the system?

Hi..
we use DPM to backup VMs on our Hyper-V Cluster. There are many VMs without any backup issue, but 5 of them failed with error:
An unexpected error occurred while the job was running. (ID 104 Details: The filename, directory name, or volume label syntax is incorrect (0x8007007B))
* DPM can successfully create the backup Snapshot but revert them after 50 sec
* No equal Eventlog errors
I've tried many steps: rejoined VMs to cluster, removed any snapshots, export -> delete -> import (with new ID), reinstalled DPM Agent, rebooted Cluster Nodes...
The error still persists.
Environment:
* Cluster Nodes: Hyper-V Server 2016
* DPM: Host OS: Win Server 2016, DPM 2016 RU4
Please help me :)

Hi,
How can I calculate the Daily Churn %, for DPM 1807 with MBS and Hyper-V protection (24 TB today)
Daily Churn %: This is the average churn on the protected data that DPM sends to Azure Backup every day. If I find how much data DPM sent to Azure compair with the size of all VMs is that theDaily Churn %?
<Data sent to Azure>/ <Size of all Hyper-V on CSV> - 10/24 = 0.41666 = 41Daily Churn%?

Hi,
I am currently configuring DPM 2012 R2 in a hosted environment. As part of this I am trying to test the recover of a Hyper-V VM to a different physical host from its original location using the "Recover as virtual machine to any host" option. However when using this option all it seems to do is move the virtual machine from 1 physical host to another and does not apply the recovery point.
Current environment configuration:
3 x Physical Server hosts (all Windows Server 2012 R2) configured as a failover cluster (inc storage)
Hyper-V 2012 R2 role installed on all 3 hosts
System Center VMM 2012 R2 used to manage Virtual Machines
Steps used in the process are as follows:
1. In the DPM console select the Recovery option
2. Browse to the VM you want to restore
3. Expand the VM node and select "All Protected Hyper-V Data"
4. Select Recoverable item in the Path list
5. Right-Click and select "Show all recovery points"
6. Select the recovery point to restore and click Recovery
7. On the Review Recovery Selection page click Next
8. Select the "Recovery as virtual machine to any host"
9. Click Next
10. Click Browse
11. Select the Hyper-V physical host and clustered storage location for where the VM is going to be recovered to.
12. Click Ok.
13. Click Next
14. Click Next again
15. On the Summary page click Recover
16. The recovery process with proceed and restore the virtual machine to a different physical host but will not recovery the virtual machine as per the recovery point.
Can anyone please confirm if I am using the correct process or whether I am doing something obviously wrong in this process?
ILR on a VM errors 99% of the time while loading. The VM is a 3.5TB file server and after I click through the volume to the share, it may load a few thousand files and then error. There is 26000 folders. What’s weird is sometimes (not often) it will just click through the vhd folders and load all files as expected. I would also love to browse the vhd that DPM loads in the DPM folder, but can’t access it. I really want this to work as ILR especially is a great feature!
We are using DPM 2016 rollup 6 on a VM with 12 cores and 12 GB ram. Other (smaller) vm's volumes load perfectly.
The errors: -
DPM failed to access the path NO_PARAM - ID39
DPM cannot browse the contents of the virtual machine on the protected computer...... - ID958
Any ideas?
Many thanks.
Hi everyone!
I recently purchased and set up a Windows Server 2016 Essentials machine and want to perform regular backups. These backups however keep failing. I'm going to try to include all of the specifics below:
So, it fails at Sytem State and Bare Metal Recovery...
The error for System State and Bare Metal Recovery is: One of the system components is not consistent in the shadow copy created for backup.
The error for all of the others is: The writer's timeout expired between the freeze and thaw events.
This happens every time I try to do a backup...
I am backing up to an external hard drive. When I start the backup, it advises that the external drive is included in the backup and asks me if I want to omit it (which is fine because that is a backup drive and shouldn't be backed up also). I choose "Yes" and the backup proceeds. The following morning though and I have all of these errors and a backup that, presumably, is worthless...
Has anyone seen this error or know how I can fix it going forward? I backup important data separately, but would like a backup of the actual server too.
I have searched online, and while I've seen some discussion of similar issues, I haven't found an actual solution anywhere.
Thanks again for your help!
Hi,
1a) I have been informed that the disk (DPM storage LUN) IO payload size (disk data transfer block size) (i.e. whilst reading/writing the VSS snapshots) is 64KB for both reads and writes.
1b) Or have I been mis-informed and what my source actually meant... is that the 'disk volume blocking factor' of the storage LUN for DPM is 64 KB, i.e. that the many GPT partitions which comprise used DPM storage space have a blocking factor of 64KB ?
1c) Or, are both statements above true?
2) If (1a) above is true, then is there a way to increase the IO payload (disk data transfer) size, and thus move more backup data per IO ?
3) I've also been told that a DPM server instance might also typically require a large amount of page file space. Can someone explain why this might be the case? Could this be overcome by providing more RAM? Or is there something inherent in the design of DPM as an application that simply requires 'N' x RAM for page file space?
4) The requirement of a large amount of page file space would seem to indicate to me that the page file will experience lots of activity, and thus that the page file for a DPM server instance (physical or virtual) should itself be placed upon the fastest possible storage. True?
Thanks.
I have a 2 node hyper-v cluster with a csv shared between both nodes. I just set up dpm 2016 and installed the agent on both hosts and added the vm's to a protection group, but when I try to take the initial backup it looks like it is about to but after a few seconds it just goes back to "replica is inconsistent". I looked in the event viewer, but the only logs i can see that pertain to this is event ID 33223, which just says it failed and nothing else.
Kind of lost, still pretty new to hyper-v clusters as well as DPM so i could use some guidance, thanks!
Hi.
Has anyone experiences with the exclusion of VHDs from Hyper-V backups with DPM 2016? Does it still work? Are there any known issues with it? I try to exclude specific VHDs with Set-DPMGlobalProperty -HyperVPagefileExclusions "servername-Disk1.vhdx,servername-Disk2.vhdx", but it does not work.
Best regards
Andreas
Hi,
Can I backup a full Hyper-V guest VM running server 2016 with Oracle application. I am using DPM 2016 to backup full VM's. Just not sure how windows handle the Oracle database?
Will such a backup restore the full system with Oracle DB ok?
thx
Robert
I have a 4 node S2D cluster with hyper converged network.
Created a backup network and given it a dedicated subnet. 10.11 in my case.
I created a local hosts file on DPM pointing to all the sources i backup, which in this case is the 4 nodes.
On each node i created a host file pointing at the dpm server dedicated backup vnic.
All can ping.
when i have only the dedicated backup network in, all replica's fail. When i add the production network in as a 2nd network..sequence 2, all backups get thrown over that network.
my question is does the cluster name itself.....also need a 10.11. network address as dpm is accessing the cluster to find resources.
i just cannot get this working after following every known guide. i dont want backup traffic going over production network as its gives false positives on data transfer.
Thanks
