DPM 2012 table backup

Dear all,
I have intertied a DPM 2012 server which is perform short (to disk) and long (tape) backups. However the tape backups always seem to fail with various errors / warning. I have noticed that the server has fire streamer and a physical tape drive setup,
I would like to remove fire streamer and also get some granular logon on the errors so that I can perform some analysis.

Hi,
What update rollup are you running on the DPM 2012 R2 server ? DPM 2012 R2 UR5 introduced a new refresh feature that will re-enumerate data sources on an individual protected server.
Check for VSS errors inside the guests that are having problems being backed up.

DPM encountered a retryable VSS error. (ID 30112 Details: VssError:The writer experienced a transient error. If the backup process is retried,
the error may not reoccur.

All the vss Writers are in stable state
Also Some Hyper-v VMs are not appearing in the DPM 2012 R2 Console When I try to create the Protection Group please note that they are not part of cluster.
Host is 2012 R2 and The VM is also 2012 R2.

DPM 2012 R2 backup of Workgroup computer error

Hi, we have a Workgroup server that we had successfully backed up to a DPM 2012 Server.
Since then we have built 2 brand new DPM 2012 R2 servers.
I have uninstalled the DPM 2012 agent from the Workgroup computer and have installed the new DPM 2012 R2 agent successfully.
However, when i try to Attach the agent I am getting 'Unable to contact the protection agent on server' errors.
I have run the Set-DPMServer -IsNonDomainServer command correctly so the Firewall rules are there ( I have also turned the FW off to test but same error results). I am using the same account details created via Set-DPMserver to attach the agent on the DPM
server.
The Event Logs on the DPM 2012 R2 server show DCOM errors (Event 10028, DCOM was unable to communicate with the computer using any of the configured protocols; requested by PID 5e4 (C:\Program Files\Microsoft System Center 2012
R2\DPM\DPM\bin\msdpm.exe).)
I have even uninstalled the 2012 R2 agent and re-installed the 2012 agent and that attaches fine, no problem.
Can anyone help/advise?
David

Hi,
That is correct, ISCSI / Vfc attached or Pass-through disks are not included in host level backups. You have install a DPM agent inside the guest and protecting the volumes seperatly.

Can DPM 2012 R2 backup SQL Server 2012 AlwaysOn enabled databases

Is it possible to use DPM 2012 R2 for backing up
SQL Server 2012 AlwaysOn enabled databases ?
Because if Alwayson configured for any Database , particular database is not available to select for backup.

Hi,
Yes, starting with DPM 2012 SP1 SQL AlwaysOn enabled databases can be protected as long as they are not part of sharepoint farm. DPM shows the Availability Groups under Cluster Group.
You must explicitly add the system account NTAuthority\System or NT AUTHORITY\DPMRA to the Sysadmin group on SQL Server.

DPM 2012 R2 backup Causes Redirected CSV IO on SOFS Cluster.

Hi, I have a Scale out Storage Spaces Server with 2 nodes, and a 10 node 2012 R2, Hyper-V cluster using this via SMB3.0
I also have installed a DPM2012 R2 backup server.
the DPM agent is installed on all nodes of all servers and I have followed the pre-requisite from Microsoft for setting up DPM backup of SMB Hyper-V machines.
The DPM backups all work fine. but occasionaly I get these errors on the SOFS cluster.
Cluster Shared Volume 'Volume3' ('Cluster Disk 4') has entered a paused state because of '(c0130021)'. All I/O will temporarily be queued until a path to the volume is reestablished.
I really thought this issue had been resolved in this revision, this doesn't seem to cause any issues with my VM's that I can notice. and all DPM backups are working fine, but it still causes me concern.
has anyone else seen this or have any suggestions what I can try to resolve.
Regards
Mark Green

We also encounter this issue. We use Windows Server 2012 R2 and SCVMM 2012 R2 (with RU1). Be carefull with this issue, because it can cause serious issues. Btw, note that Windows Server 2012 R2 used Direct I/O instead of Redirected I/O.
If you can't find a full fix as we are in right now, there are two things that might offer a work-around for you:
Disabled ODX (if your storage system does not support it):
Deploy Windows Offloaded Data Transfers
http://technet.microsoft.com/en-us/library/jj200627.aspx
Serialize virtual machine backups per node
Migrate to a hardware VSS provider
http://technet.microsoft.com/en-us/library/hh758027.aspx
The second option works best, because this issue mostly occurs when you run a backup of many VMs at once. It it not a full fix and makes you backup windows much longer, but can avoid you other problems. Also keep a close eye on this link:

DPM 2012 SP1 Backup to Cloud

I realize I'm going to be a little ahead of where the software is on this one but on the subjects of backups, DPM, Instead of pointing DPM to the azure public cloud can I use our Private Cloud (Windows 2012, System Center 2012 SP1 + Azure Services for
Windows Server)?
Thanks
Si
Simon Stearn - Militant South - Agile Architecture

I assume that when you say Azure Services for Windows Server, you are referring to Windows Azure Pack?
If you are doing this on premise then I think you would need to stick to the conventional DPM-to-DPM model?
I can't personally imagine that the DPM team will add the ability to use the Cloud Backup feature with an on premise Azure cloud as the capability for on premise off-site backup is already there in DPM-to-DPM.
Thanks,

DPM 2012 R2 Bug: Unable to backup a VM with the same name as an old VM

Scenario:
You have a VM called "Virtual Machine 1" running on a Windows Server 2012 R2 Hyper-V cluster and you backup this virtual machine using DPM 2012 R2.
You remove "Virtual Machine 1" from DPM, selecting delete replicas and expire all tape backups, and then delete the VM from the cluster as it is no longer required.
Later you create a new virtual machine called "Virtual Machine 1" on the same cluster. You attempt to backup the VM with DPM however when attempting to add the VM to a protection group you get the error "DPM cannot access the path \Online\Virtual
Machine 1 because part of the path has been deleted or renamed. Check the path and enter it again". Refreshing the data source/clearing the cache doesn't help
The only solution I could find that worked was to delete the data source record in DPMDB..tbl_IM_DataSource for the virtual machine. This also required deleting records that referenced the DataSourceId in other tables.

Hi
yo need to clear the Cache on the ProtectionGroup Wizard.

How to backup Hyper-V host server on DPM 2012 R2

Hi,
I'm about to backup my first Hyper-V host server using DPM 2012. I'm looking for a strategy to back up both the host server and virtual machines. Note: I'm not really interested in backing up all the virtual machines. Many are non-production
or for testing. How do you do it? I was thinking about selecting in the protection group:
- BMR and SS for the Hyper-V host
- The C: volume of the Hyper-V host
- Select the Child partition snapshots of the virtual machines I want to backup.
In my environment, Hyper-V role is installed on the C: drive, but the virtual machines are stored on E:, which I would not backup directly (volumes) since I'm backing up the VMs using Child partition snapshot.
Would I be able to restore my Hyper-V host and the selected VMs with a backup like this?
Anyone want to share how they setup their protection groups for Hyper-V?
Thanks.

No, use full server backup (image) if VM config are stored at default storage (disk C).
Understanding where your virtual machine files are [Hyper-V]
Using this method to perform a full server backup is the recommended method because it captures more data than the other method.

Online Backup of supported Linux VM on Hyper-V 2012 R2 / SC DPM 2012 R2

Hi,
I'm trying to set up a lab environment:
Win 2012 R2 with Hyper-V
running 2 Linux Machines:
Linux2 - CentOS 6.4 with manually installed Linux Integration services 3.4
Linux3 - CentOS 6.4 without LIS (should be already included in CentOS)
Another machine running Win 2012 R2 Server with SC DPM 2012 R2
but both VMs show as "Offline" when trying to back them up via DPM. Tried local Windows Server Backup with the same result.
I am able to backup the VMs "offline" (pausing the VM, taking snapshot, resume VM) but according to MS, SC DPM 2012 R2 should be able to do Online backups for supported Linux VMs (http://blogs.technet.com/b/virtualization/archive/2013/07/24/enabling-linux-support-on-windows-server-2012-r2-hyper-v.aspx)
The only things in the EventLog are these:
A storage device in 'Linux3' loaded but has a different version from the server. Server version 6.0 Client version 4.2 (Virtual machine ID 4F5CDDD8-B855-41CF-83B2-772C1B99090D). The device will work, but this is an unsupported configuration.
This means that technical support will not be provided until this problem is resolved. To fix this problem, upgrade the integration services. To upgrade, connect to the virtual machine and select Insert Integration Services Setup Disk from the Action menu.
Any Ideas ?
Thanks

Hi,
That list would need to come from the Windows hyper-v group, they are responsible with adding the feature to the integration components for various Linux OSes. DPM just backs up whatever the hyper-V writer presents to us, if the guest supports
online, we back it up online, if not hyper-V saves the guest before the VSS snapshot is taken and DPM takes the backup from the saved state.
NEW NOTE ADDED 1-29-14: Windows group just released “Linux Integration Services Version 3.5 for Hyper-V”. The
document mentions that some versions of Red Hat and CentOS are now
supported to do online backup.
Live virtual machine backup support
======================
RHEL/CentOS 6.0-6.3
RHEL/CentOS 5.7-5.8
RHEL/CentOS 5.5-5.6
ADDTL NOTES: If there are open file handles during a live virtual machine backup operation, the backed-up virtual hard disks (VHDs) might have to undergo a file system consistency check (fsck) when restored.
Live backup operations can fail silently if the virtual machine has an attached iSCSI device or a physical disk that is directly attached to a virtual machine (“pass-through disk”).

Backup fails for a Hyper-V guest with VSS Writer failures using DPM 2012 R2 - Hyper-V guest has Oracle application installed,

I am trying to backup a VM which before it had Oracle installed backed up with no problems. It is a Windows 2008 R2 server which sites on an 8 node Hyper-V 2012 R2 cluster (with CSVs). I am using DPM 2012 R2 to run the backups which have been
successful for the last few weeks but then Oracle was installed and the backups have failed since then.
The job fails and a large number of VSS writers go into a 'Failed' state with the 'Last Error' showing as 'Timed out'. I then get 4 popups appear each referring to a 'temporary' drive which appears briefly in Disk Management with a RAW file system.
These pops say "You need to format the disk in drive X: before you can use it. Do you want to format it?" (where
X: is replaced by the drive letter assigned to each 'temporary' drive).
The System event log is populated with a large number of warnings with Event 51, Disk, stating "An error was detected on device \Device\Harddisk<number>\DR<number> during a paging operation". There are also a
few warnings for Ntfs (eventid 57) stating that "The system failed to flush data to the transaction log. Corruption may occur."
Prior to these warnings there are 5 other warnings for partmgr (eventid 58) stating "The disk signature of disk
<number x> is equal to the disk signatuire of disk <number y>" and 4 errors (eventid 1, VDS Basic Provider), "Unexpected failure. Error code: 490@01010004".
There is a script which is run to stop the Oracle application on the server and if this is run then the backups will complete successfully. We have been troubleshooting this by running a certain amount of the script and seeing which part affects the
backup and it seems that if the Weblogic (wls_reports) service is stopped then the backup will succeed but if it is running then the backup will fail and the above symptoms occur.
Another point which may help is that there is a pre-production server which resides on a Windows 2008 R2 Hyper-V standalone server, has the same scripts and installation of Oracle but backs up without any issues.
I have experienced VSS writer failures before with VM backups but I have not seen this before. It is not intermittent and I can find no work around to alleviate the problem of having no backup (except stopping this service or shutting the server down,
but as it is a production server this is not practical).
If anyone has experienced this before or have any suggestions / advice it would be much appreciated.
Thanks
Chris

Hi Chris
I have exactly the same issue.
2008 R2 Server running Oracle
6 node 2012 R2 Hyper-V Cluster with CSV
Exact same errors and popup "format disk" message.
DPM2012 R2
I also have some other VM's on the same cluster which do back up through DPM
The only difference I can see is the server which has the issue has a legacy network adapter.
Production server so cannot make any changes until later but will add new adapter and report back.
Interesting about the Weblogic service, may test this also.
Cheers
Kev.

What I have done to try to troubleshoot this issue is:
Reinstalled DPM - No sucess
Restarted the Hyper-v Host - No sucess
I'm at the point where I am out of ideas and google hasn't given me much.
/Joseph

i have the same error.
"vssadmin list writers" shows last error unknown for all writers
disk space is sufficient
ntbackup of systemdrive and systemstate runs fine.
i installed KB940349 which fixes some vss related issues but the problem is still there.
any ideas?
Thanks.
When you have vssadmin reporting unknown error the only way to reset the vsswriters (as I understand it please correct me if I'm wrong :) ) is to restart the machine. The Fellenator is correct, make use that the vsswriter is working correctly since this
is the main function DPM is using when taking backup. He's also right in saying that it's outside the scope! Create a new thread on your error, then you will get much better responce!

Some free tapes are not used by backup job - dpm 2012 r2

Hi,
I have DPM 2012 R2 with IBM TotalStorage 3572 tape library. It is 8 slot tape library. All was working with initial 8 tapes I added to tape library. I had one Protection group to be archived on 8 tapes. I was doing Daily and weekly backups. Every 2nd week
I would do a weekly backup and keep it for 2 weeks i.e. I need 2 tapes for weekly backups. All was working ok until I introduced two new weekly tapes as a replacement for 2 weekly tapes in library. Because of disaster recovery procedure - I have to take
weekly tapes out of library and store them in disaster recovery location for some time. So I pulled out 2 weekly tapes and added 2 new tapes. New tapes were marked free and they are showing as Free tapes.
Now - the trouble is that these 2 free tapes are not used by backup job and instead - backup job writes weekly backup on any of the available Daily tapes (like from 4-5 days ago) instead of using one of the Free tapes that are available.
I'd like the backup job (Protection group) to use Free tapes first and only if there are no available free tapes - to go and do backup on Daily tape or ask for a free tape.
I am probably doing something wrong here - so I would really appriciate if anyone can help me with this? Any ideas?
Thanks,
Damir.

Hi,
What update rollup are you running on the DPM 2012 R2 server ? DPM 2012 R2 UR5 introduced a new refresh feature that will re-enumerate data sources on an individual protected server.
Check for VSS errors inside the guests that are having problems being backed up.

DPM 2012 R2 Rollup 4, Update Rollup 7 for Exchange Server 2010 SP3 backups with eseutil check fail

Hi,
It could be a coincidence, but ever since installing Update rollup 4 onto DPM 2012 R2, (which was at UR3 I believe) I haven't been able to complete an Exchange express full backup or consistency check with verification using Eseutil checked. If I have the
eseutil check enabled I get the following error:
Type: Consistency check
Status: Failed
Description: Data consistency verification check failed for LOGS of Exchange Mailbox Database Mailbox Database 2011112513 on SERVER.xxx. (ID 30146 Details: The process cannot access the file because it is being used by another process (0x80070020))
Disabling the eseutil verification allows it to succeed, but I'm not happy to continue with that for too long.
I've had this running for many years and this is the first real issue with exchange, its a single stand alone exchange database.
Any ideas?
Thanks,
Andreas

Andreas,
the error is stating that something else has a handle to a file or files during the ESEUtil check. Typically this is AV. I have also seen where the Exchange limits are exceeded and that causes the issue.
Please ensure you have the DPM AV exclusions for the DPM server and I would advise the DPMRA.exe on the PS. You can also trying disabling or removing AV as a test.
DPM AV exclusions -
http://technet.microsoft.com/en-us/library/hh757911.aspx
You may also want to test using eseutil against the logs outside DPM and see if that fails with similar issue. Let us know. Thanks

The server is part of a protection group that is co-located, I am trying the backup not as part of a co-located set to see if this makes any difference.
Tape backups for other servers, which are part of the same co-location group, work fine and it seems to be just this one causing the issue.
I have seen a few other posts on the net referencing "WARNING MediaPool 00000000-0000-0000-0000-000000000000 does not exist." where people have similar issue with DPM crashing out but so far nobody seems to have any answers.
I am debating removing the protection group and trying to 'start from scratch' but wondered if anyone else had any thoughts ?
Thanks in advance,
Ed

Hi,
Open SQL management studio and connect to the instance used by DPM.
Run the following Query against the DPMDB and see if it returns any rows, if so please provide the output.
select MP.mediapoolid, MP.PGSETID from dbo.tbl_MM_MediaPool MP
Join dbo.tbl_IM_ProtectedGroup PG on PG.ProtectedGroupId = MP.MediaPoolId
where PG.MediapoolId is NULL
and MP.PGSetId is not NULL

DPM 2012 R2 UR4 and BMR backup from physical 2008 R2 (DC, DNS, DHCP,WSUS, WDS)

Hi,
I'm completely lost.
We updated from DPM2010 (2008 R2) to DPM 2012 R2 RU4 (2012 R2).
Clean install. Same hardware. Everything went quite smoothly.
Our new (and also old did the same thing) DMP protects some Hyper-V guest on our 2008 R2 Hyper-V cluster, one Exchange (2010) DB's and SQL 2008 R2 DB's and one physical server - 2008 R2 (DC, DNS, DHCP,WSUS, WDS ~160GB of data).
Currently we are using some Buffalo Terastation's III (TS-RIXL) iSCSI SAN storage to hold our DPM protected data.
Configured as RAID 5.
Our new DPM server is connected to those iSCSI devices using built in MS iSCSI initiator via secondary NIC on this server using dedicated iSCSI subnet.
Everything seems to be fine unitil System State and BMR (I'v checked both) runs.
Basically my iSCSI NIC shows Write about ~170Mbit/s and Read about 520Mbit/s when backing up virtual machines, Exchange or SQL.
When it comes to System State and BMR backup the trouhgput is MUCH slower (about 65Mbit/s) and I can not figure out why. I understand that the BMR backup initiates direct writing to the DPM created and shared replica volume on my iSCSI NAS (my wording
might be not correct but basically I understand how this works). But I don't understand why the speed is so much slower. I'v tried everything, googeled around, changed NIC drivers, firmware etc. No luck.
If I just copy some big ISO file from/to server to DPM or vice versa the speed is arount 100MB/s (as reported by windows itself). So it seems to able to utilize full network speed. But why this backup is so slow? I'm excpecting to see speed about ~170Mbit/s
because it corresponds my iSCSI Write speed as seen when backing up hyper-v guests and DB's..
What I'm doing wrong?
Any help is appreciated :)

Hi Sven,
Sometimes BMR is slower than backing up virtual machines (VHDs). If there is a free local disk, please test to do a backup locally to see the speed. From your description a common backup works much faster so let's see if it is the backup speed which causes
the issue or not.
