Replica of virtual DPM

Hi,

I am wondering if it would be possible to turn on hyper-v replica on a virtual DPM 2012 R2 running as a vm in hyper-v (separate standalone hyper-v host).

I am having issues using a secondary DPM to backup the primary DPM server and thought possibly i could just replicate the entire primary DPM server to the DR site.

I believe it would be technically possible, but am wondering about the stability and possible corruptions when replicating a 60+TB DPM server.

Any thoughts?

DPM 2012 r2 secondary server slow to list datasources

September 7, 2016, 4:01 am

I have 2 DPM servers, both latest updates 2012 r2

They are set up as primary and secondary.

They are set up to protect live migration between hyper-v clusters.  They are also protecting physicals servers with agents. All this is working perfectly.

Problem is on the secondary server, when i select datasources to protect from the primary, it will take hours before im able to select anything. Earlier i have opened the console in the morning, and come back later in the day and added what ever needed changing. 

But now i have to reorganise on the secondary server and it is killing me.

It is not only slow when you refresh the datasources, it is slow everytime you open the protection group wizard. Listing the Primary server itself  from the secondary is instant, only listing the primarys protected sources is slow.

On the primary server the listing of protected sources  is instant everytime.

There has to be something wrong to make it this slow? I cant find anything wrong, and there are no errors.

Hello,

I just installed the "Microsoft Azure Backup Server" (I'm not sure if I'm in the right group...) for a backup of some Hyper-V client servers (4).

3 of the servers seem to work (replica was created and staus is OK) but one server isn't working. The issue startes creating the replica fails with the Message:

----
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 server is a Small Business Server (Windows Server Standard FE, Service Pack 2).

Thanks for any help...

DPM with VMM backing up replicas - is this normal?

Hello all,

Environment Information

DPM Console 4.2.1417.0

VMM Console 3.2.8169.0 (on DPM and VMM servers)

Stand-alone Hyper-V Servers managed by VMM.

Azure Client installed for Replication management and failover

We have a DPM server and a VMM environment with multiple standalone hyper-V servers that replicate their guests.  We use Azure to manage VMM and Hyper-V replication for failover purposes.  After setting up the environment and re-configuring DPM I noticed that it detects the guests as being on the replica servers and is backing them up from there.

Is this expected and normal?

I can successfully recover files from this scenario, but could not find any documentation that indicates this is how it works.

DPM 2012 R2 Hyper-V backup of SQL server VM

Hello!

I have a question about using DPM 2012 R2 in Hyper-V 2012 R2 cluster and backing up Windows 2003 VM, that has SQL 2008 installed.

When i use VM, host level backup with DPM2012 R2, would it trigger a full DB backup on SQL server or not?

Problem is, that we are using SQL (maintanance plans) for backing up databases and doing transaction logs backup. 

I want to back up the whole VM, but i want to be sure, that this would not mess up SQL backup inside the VM?

Is it possible, that i wont install DPM agent inside the SQL server VM? But can i then still restore files from the VHD/X or only entire VM?

Hi,

I have following setup:

- Backup System: System Center 2012 R2 DPM installed as VM

I have two questions:

1) I want to protect a VM that happens to be on the same host with DPM, is it possible to do this kind of backup? the storage pool composed of vhdx using DAS.

2) I checked the document online about host/guest level backup, I installed the DPM agent on the host machine but I only want to backup particular VM on that machine, by definition it should be included in host level backup, but I only want to backup entire information about specific VM (related: VM configuration file, virtual hard drive(s), etc), is it possible to do this?

Thanks in advance,

JL.

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,

DPM online backup causes Hyper-V Manager uptime resets

January 6, 2015, 2:00 pm

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

File Server Cluster Backup

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?

DPM 2012r2 Issue backing up 2 Hyper-V VMs

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?

DPM 2012R2 and Hyper-v2012R2 Cluster / NetApp SMB Storage

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.

Hyper-V Cluster Backup problem: Unexpected failure. Error code: 48F@01000003

March 26, 2014, 5:47 pm

We have several 2012R2 datacenter Hyper-V hosts with several CSV's to a HP 3PAR FC SAN, managed with SCVMM 2012R2 and backed up with DPM 2012R2. We have been running fine and doing backups with agents in each VM. 

All hosts are regularly updated with Cluster Aware Updating.

Recently I thought I'd set up Hyper-V host backups because I hope it will make DPM easier to manage, and I believe it uses far less bandwidth and I/O's. Initially, I selected about 15 vm's to backup from the cluster node in DPM. This managed to crash 2 hosts and I've searched everywhere for a solution. One link suggested it is a 3PAR ODX issue, but I disabled ODX by this:

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 :)

VM Backup with Linux Fedora 23 not working

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:
   PrepareForSnapshot Event

Context:
   Execution Context: Writer
   Writer Class Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}

   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?

Best Practice for DPM + Hyper-V Cluster + CSV + Fibre Channel Backups?

December 4, 2015, 1:13 am

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.

Extra information:

- 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.

Backing up a guest VM at Host level causes 'replica is inconsistent'

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.
