Hello,

I am trying to backup a VM on a Windows 2012 cluster, I keep getting the below error:

DPM encountered an error while performing an operation for \\?\GLOBALROOT\Device\CSV{de67579e-7ab9-4cf9-bb65-a35209fa8db6}\Server\Server.vhd on Host (ID 2033 Details: Incorrect function (0x80070001))

This server has been backing up fine for a long time, it started to fail on 25/09/2016.  There are other servers on the same CSV that are backing up fine.  I have tried to run a chkdsk on the server, it came back with no errors.

The affect server is a Windows 2012 Standard server.

I have also removed the server from the protection group and re-added, but the same error is displayed after a little while consistency checking.

Any help would be appreciated.

Kind Regards,

Sean Buckle

We are experiencing resets of the uptime counter in the Hyper-V Manager when backups are taken by the DPM (r2)

The VMs that suffer from the issue are all on a new R2 cluster that uses another SOFS cluster via SMB for all VM disks. 
All requirements for online backup should be in place, and all servers run fine while being backed up. When backing up the servers do create a new checkpoint, but as i understand this is the correct behavior when using DPM R2 on a Server 2012 R2 cluster.

Before installing the SMB share VSS role, and upgrading Integration services on some VMs, only Offline backup was an option, but after correcting these issues DPM allows online backup - but uptimes are still being reset.

No servers are entering saved state or otherwise being reset while backed up. Event logs show no errors regarding to "hot" backup, and the guest OS' show correct uptime when checked . 

Is the resetting uptime a sign that i still have issues with online backup, even if everything seems correct? And if not, how do i avoid the uptime being reset. I know that its not technically even the correct uptime, and even resets from migrations, but still..

Hello!

I create PG of Hyper-V cluster. Have a few VM with SUSE12. When I try to create replica of SUSE VM in event viewer I see error that VSS provider is in a bad state.

The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError:The writer experienced a non-transient error.  If the backup process is retried,
the error is likely to reoccur.
 (0x800423F4))

Can the DMP in 2016 to do online backup of a VM on Suse 12? I found a similar article, but that's about 2012 R2. DPM 2012R2 supports online backup SUSE 11SP3.

SUSE 11SP4 online backup is performed, and SUSE 12 is not performed. 

I will be glad of any help

Hi, 

Good day! 

Background: 

I have 2 file servers setup as a clustered.  We setup a shared storage drive for the file servers.   

When server A becomes active, it will have C drive and G drive while server B will only have C drive. 

Once I moved the cluster role to server B,  B will then have C drive and G drive while server A have just C drive.  

Both file servers are installed with DPM agent and backup using DPM.  

We configured DPM to group both server A and server B under the same protection group.  

Issue:  

While server A act as active file server (holding file cluster role), DPM has no problem back up the server.  But DPM always failed to backup server B which is passive. 

While server B act as active file server, DPM will then OK to backup server with no issue but will fail on server A.  

So looks like DPM only manage to backup active file server that in the cluster.  

is there anyway that I could overcome this?  

I'm running a 3 node Hyper-V Cluster with approx. 25VMs and have an issue backing up 2 VMs. - All other VMs are backing up without issue.

The two VMs will show as replica inconsistent and will not perform a consistency check unless I manually create a snapshot/checkpoint within Hyper-V Manager.  Once created DPM will happily perform a consistency check and backup up the 2 VMs.

If I remove the snapshots/checkpoints - DPM will fail on the next scheduled backup and show the VMs as inconsistent again.

Anyone any idea?

Hi all, I have a "True or False" question. If I have a six node Hyper-v 2012R2 cluster using a NetApp SMB share, defined in VMM, for virtual machine .vhdx file storage, will I be able to back up all of my virtual machines using a virtualized DPM2012R2 server?? I read where you have to install a DPM agent on the hyper-v nodes AND the smb file server. You can't install that agent on the NetApp.

One other question is: Can I define a DPM storage pool on a Netapp share if I define the share in VMM and then use VMM to create a disk for the DPM server on that share? 

Any feedback appreciated. Thanks.

http://flemmingriis.com/dpm-2012-r2-windows-server-2012-r2-disable-odx/ and the issue persists.

Specifically, the error is: Event 1 VDS Basic Provider, Unexpected failure. Error code: 48F@01000003.

These occur several times then the CSV goes offline and all the VM's crash. Needless to say, this is catastrophic and a bullet proof solution needs to be found.

I'd appreciate any help :)

We have a 2012 R2 Hyper-V cluster and we are using DPM 2012 R2 UR8 to backup our VMs.  We just updated 3 VMs from Linux Fedora 19 to Fedora 23 and now after updating to Fedora 23 when the VM backups run, they are failing with this error in DPM: "The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError:The writer experienced a non-transient error.  If the backup process is retried, the error is likely to reoccur. (0x800423F4))"

The VSS writer "Microsoft Hyper-V VSS Writer" also goes to a failed state and has a last error of "Non-retryable error"

In the Windows Application Event log this is the error: "A VSS writer has rejected an event with error 0x800423f4, The writer experienced a non-transient error.  If the backup process is retried, the error is likely to reoccur.  Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.

Operation:

Context:
   Execution Context: Writer

   Command Line: C:\Windows\system32\vmms.exe
   Process ID: 24236

I've reset the VSS writer but that hasn't fixed it.  I have also removed it from DPM and re-added it with no luck.

Does DPM 2012 R2 UR8 support this kind of backup with Linux Fedora 23?

Any ideas how to make this work?

Hi,

we´re evaluating Hyper-V and DPM at the moment. The test setup is as follows:

- 1 FC SAN, created various Volumes, added to the Hyper-V Cluster as CSVs

- 3 Hyper-V Hosts running as a Hyper-V Cluster with FC connection to the SAN

- 1 Physical DPM Server with local Backup storage and also FC connection to the SAN

As I understand, DPM installs the DPM Agent on the 3 Hyper-V Hosts. Within DPM I create a Protection group, selecting the Cluster itself and the VMs it should back up. The Backup process then connects via LAN to the DPM Agents on the Hosts and pulls the Data for the backups from the CSVs.

Now since the DPM also has a FC connection to the SAN, I wonder if I could utilize that one somehow. This will be a huge performance boost (SAN is 8GBit/s, LAN is only 2GBit/s in a Team). I may be completely off with that. But could I just join the DPM Server to the Hyper-V Cluster also, so it has access to the CSVs? DPM will not be used to place VMs of course. But with direct access to the CSVs, would it pull the Data directly from the CSVs via FC?

Or is this idea just plain stupid and it might work, but will break things when going into production? I just wonder if I could utilize that FC connection from the DPM Server to the SAN in some way to speed up backups and restore operations.

Any input to this topic is appreciated. Thanks in advance :-)

When we attempt to restore a Server 2016/RCT Virtual Machine either to it's original location, or to another Hyper-V host, the restore fails right at the end with one of the following error messages:

- An unexpected error occurred while the job was running. (ID 104 Details: Unknown error (0x80041024)
- An unexpected error occurred while the job was running. (ID 104 Details: Unknown error (0x80041008)
- The protection agent on xxx was temporarily unable to respond because it was in an unexpected state. (ID 60 Details: Internal error code: 0x809909B0)

The files are copied to the intended destination and we can manually import them into Hyper-V successfully.


This event is recorded on the Hyper-V target host around the time of the restore:

- Our DPM server was originally built on Server 2012 R2. DPM 2012 R2 was initially installed. 
- It was recently upgraded to DPM 2016 and UR1 was installed.
- The DPM host OS has not yet been upgraded - is this necessary to get RCT VM restore working??
- All protection agents are up-to-date
- We can recover VMs (non RCT marked) that have been backed up from our 2012 R2 and 2012 Hyper-V hosts to all Hyper-V hosts, including the Server 2016 ones without issue.

Hi,

I am unable to restore a Linux VM to its original instance, restoration goes till the end and fails with below error:

The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError:The writer experienced a non-transient error.  If the backup process is retried,
the error is likely to reoccur.

And i see below event in Hyper-V host:

Please help

DPM 2016 on physical Windows 2016 server

Trying to add a virtual machine guest on a 2012 R2 cluster.  None of the VMs in the cluster are selectable. The VMs that I installed agents on do list as their own computers as well, and I could make back ups from inside the guest, but i cannot back them up through the HyperV Host cluster listing.

I have a Hyper V cluster with guest VMs. 

All systems are joined to the same domain.  All systems are Windows server 2012 r2.

With an agent installed on the guest VM, I can successfully backup the VM including BMR and system state.

However, when I try to backup at the host level, which is a requirement for us, it fails.  I have hit a wall in the troubleshooting.  Can I get ideas of where to look next?

The hyper v vss writer looks good.  Integration services are good.  Agents are good, with windows server backup feature installed.

Hi,

we are dealing with the persisting error during backup jobs on our cluster. Originally, we had two node Hyper-V 2012 R2 cluster, SC VMM 2012 R2 and DPM 2012 R2 - this was a fully functional setup and we were enjoying our periodically successful backups. A month ago, we´ve decided to upgrade to the latest. So firstly, we´ve upgraded DPM to 2016 (but still sitting on 2012 R2 OS), then VMM to 2016 (and also underlying OS to 2016), a then we´ve performed rolling cluster update.

Now, all backup tasks against clustered VMs fails (even the first synchronization). Backup job fails and in DPM console shows:

DPM encountered a retryable VSS error. (ID 30112 Details: VssError:The shadow copy provider timed out while flushing data to the volume being shadow copied. This is probably due to excessive activity on the volume. Try again later when the volume is not being used so heavily. (0x80042313)).

Both nodes show error 12297 repeatedly. Details of each error are:

Hello,

We are using DMP2012 R2 and Hyper-V(Version: 6.3.9600.16384) of Server 2012R2. And some VMs throught Host-Level backups on different Hypver-V Hosts.

Recently I found a wired issue happens on my Jobs. Details see the attached picture.

And if I restart the "Hyper-V Virtual Machine Management service"service (this service looks ok-running) on each Hyper-V hosts and then "Perform Consistency Check..." again for each jobs, they work again(Protection Status becames OK).  This issue happened twice in one month.  So hopes someoen can help here.  Thanks, Andy

Afternoon all,

I'm looking to deploy Server2016 Nano Servers as HyperV hosts and have long used DPM as our primary backup program. I'm rather surprised to see that DPM 2016 does not support Server2016 Nano server. I know other vendors do support it - Veeam for example in their new 9.5 release - but would rather stick with DPM if I can...

I know both products are new, is there confirmed plans to support Nano server? a rough timeframe? Obviously these things are subject to change but at least the acknowledgement of support being incoming could help me stop jumping ship for a competitor.

Any feedback would be appreciated.

Thanks

Joe.

Hi,

I have few linux VMs hosted on server 2012 R2 hyper-v, which I backup using DPM 2012 R2. Backups are running fine but the problem is whenever DPM starts backing up the Linux VM, hyper-v saves that vm and restore it again in a few minutes.

Saving a running VM disconnects applications that VM is serving. I have installed latest version of "Linux Integration Services" and now I can see that DPM does shows that VM is 'Online' which was 'offline' previously but still whenever I fire a backup on DPM it saves my VM and starts backup.

Is it possible to backup Linux VM without save/restore process?

Regards,

Dhananjay

I have DPM 2012 R2 running on server 2012 R2. Dpm backup vms through Hyper-V host. Some of the vms have this additional vhd drive with name "_DoNotBackup.vhd". Used this command Set-DPMGlobalProperty -DPMServerName dpmServer-HyperVPagefileExclusions"_DoNotBackup.vhd"  few days ago. Backup occurs very night. Today I restored one of the vm which has "_DoNotBackup.vhd" and found it has latest data which means HyperVPagefileExclusions not working.

Any clue?
