Child partition backup failled in DPM 2012

Hello All,
Child partition snapshot backup failed because DPM agent unreachable. DPM agent is ok when not taking backup. but when start synchronizing the DPM agent services filled. As a result Protection backup failed after some times. please suggest

Hi
If you do a manual backup or run a consistency check what happens?
after you did the agent install did you do a reboot? Have you tried reinstalling the agent manually and setting the DPM server?

How take Branch offices backup centrally through DPM 2012 Server

Hi
I have one HQ and 200 branch offices. I want to take the backup of 200 branch offices centrally through DPM 2012 server.
To achieve this solution what procedure i have to follow. Shall i go with one DPM server at HQ or i have to configured each DPM server at branch offices.
I have 3 MBS link in each offices.
Thanks and Regards Deepak

I'm not sure there is a simple, easy answer. It depends on what you want to achieve via the DPM protection. My two cents is to have your DPM servers for the branch offices running at your HQ location so your backups are "offsite". This
will protect you in the event a branch office is lost. All protection elements except for BMR are pretty efficient with DPM and you can compress the traffic from your branch locations.
You can have multiple DPM servers at HQ and balance your server protection load across that farm.
You may want to have a DPM server at a branch location that protects some of your HQ servers to provide an offsite backup for HQ resources.
Be careful with BMR backups across WAN links. The BMR sends the entire BMR backup every time. And the BMR backup can include multiple drives if you happened to have installed applications on something other than the system drive (C:). You
can get a list of all the drives that will be included in the BMR backup by running this command on a server: "wbadmin start backup -allcritical -backuptarget:\\localhost\c$". Just hit CTRL-C after it shows you the drives that will be included.
You'll need to run the DPM backup across a private link or via site-to-site tunnels. I don't recommend trying to do a DPM backup with a firewall between the two sites. I'm sure it could be done...but I don't recommend it.

Incremental Backups Not Working - DPM 2012 R2

Hi
Having a strange issue where incremental backups in some situations are not working, however the daily full backup is succeeding.
This doesn't seem to be a SQL instance issue, in that within the same protection group, on the same sql instance, the incremental backups are working on other databases.
All of the databases are set to full recovery model, and I'm not seeing any failed jobs (although when I check the jobs, the only scheduled job is the full backup, none for the incremental backups are listed (which isn't the case for the databases that are
incrementally backing up).
What am I doing wrong?

Hi,
I recommend the following to start troubleshooting for one of the problem databases that incremental backups seem to not take place on. Carry out the below.
From DPM console select the protection tab navigate to one of the problem SQL DBs.
Select Recovery Point from the top ribbon.
Within the Create recovery point Window if you identify that the second radio button (figure 1 is greyed out) DPM thinks the SQL DB in question is in a recovery model of simple.
Ensure the SQLDBs in question are set to a recovery model of Full or Bulk-logged.
Select the protection tab navigate to Protection Group with the problem SQLDB select Modify Protection Group. From the select group member’s page select the Server in question and then select Refresh button step through the rest of the wizard and select
update group at the end.
Note if you do not see the refresh button just walk thought the rest of the modify protection group wizard and select update group at the end.

Saved State Backup on Server 2012 R2 and DPM 2012

Hello, Our environment in currently in transition with planned migration to 2012 R2. In the mean time, we have a 5 node 2008 R2 hyper-v cluster with CSV. We are currently using DPM 2012 for our backup. I have read multiple postings about child
partition backup and saved state and all that seems to make relative sense.
What I have noticed is that in our existing environment (2008 R2 Hyper-v, DPM 2012) that all 2012 R2 Virtual servers setup in our hyper-v cluster show 'Backup Using Saved State'. All virtual 2003 - 2008 R2 servers on the same cluster show as 'Backup
using Child Partition Snapshot'.
So, the question: is this normal and the only way virtual 2012 R2 servers can be backed up in our environment? Or, is there some configuration on the virtual 2012 R2 servers that needs to be done so that the Hyper-v VSS writers show that it can be backed
up using Child Partition Snapshot. (Yes, I viewed the Hyper-V VSS Writer Caption: for each system on all the nodes and no, I am not talking about what is displayed in DPM 2012 since I understand it may not truly reflect the current backup method)

Have you already checked typical reason for DPM doing saved state backup? If not, find them below.
Also, do your VM have
SCSI controller added? Prior to using Veeam as our primary backup solution, we leveraged DPM and confronted the very same issue. Fortunately, by adding ISCSI controllers to VMs in question we were able to solve the problem.
Conditions when DPM fails to back up Hyper-V virtual machines in an online state
By default, System Center 2012 – Data Protection Manager (DPM) performs a backup of a Hyper-V Virtual Machine (VM) in an online state. However, DPM cannot back up a Hyper-V VM in an online state, if one or more of the following
conditions are true:
Backup (Volume Snapshot) Integration Service is disabled or not installed.
The virtual machine has one or more dynamic disks.
The virtual machine has one or more non-NTFS based volumes.
The virtual machine Cluster Resource Group in a cluster setup is offline.
The virtual machine is not in a running state.
A ShadowStorage assignment of a volume inside the virtual machine is explicitly set to a different volume other than itself.
An App-V drive is installed on the virtual machine that creates a non-NTFS volume.
These conditions are set by the Hyper-V writer. In such a case, the VM is put in a saved state before a snapshot of host volumes are taken (except when the VM is turned off) for a backup. The Hyper-V writer adds the VM in the following format:
For offline backups: Backup Using Saved State\<VMName>
For online backups: Backup Using Child Partition Snapshot\<VMName>
Additional reason if we have less than 300MB free space on a volume in the guest.
Kind regards, Leonardo.

Not getting option to Backup Using Child Partition Snapshot DPM 2012 R2

I am running DPM 2012 R2 fully patched.
I am trying to use Backup Using Child Partition Snapshot of a Hyper-V Server 2012 R2 Datacenter Cluster using CSV.
I get no option to use Backup Using Child Partition Snapshot, just online backup.
I have gone through the steps in the Microsoft document "Configure CSV Backups"
http://technet.microsoft.com/en-us/library/hh758027.aspx (Some steps did not apply due to my not using Windows 2008 R2)
Has "Backup Using Child Partiton Snapshot" been replaced by "\Online\VMName" ?
What am I missing?

Hi,
Yes, Windows server 2012 R2 has changed the caption from "Backup Using Child Partiton Snapshot" to "\Online\VMName" - DPM is displaying the new caption when protecting Windows Server 2012 R2 guests.
MORE INFORMATION
To list Windows 2012 R2 hyper-V writer captions for guests to see if online or offline state backups will be done:
From an administrative command prompt on the Hyper-V server:
a. Type: copy con script.txt and press enter
b. Type: list writers and press enter
c. Press CTRL + Z + enter (to save)
d. Type: diskshadow /s script.txt | find /i "caption: O"
Output will be displayed for each guest as follows.
C:\temp>diskshadow /s script.txt | find /i "caption: O"
- Caption: Online\SQLSERVER
- Caption: Offline\WSS-V14
The Windows 2012 R2 Hyper-V writer adds the VM in the following format:
For offline backups: Offline\<VMName>
For online backups: Online\<VMName>

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.

DPM 2012 R2, Windows 2012 R2, and "stop" VM during backup

I did upgrade
DPM 2012 SP1 to 2012
R2.
DMP backup the server with Hyper-V
machines, windows / linux.
The previous version of Windows, as
did backup via partition shapshot
not stop its operation.
Current unfortunately it does!
During backup closes all connections
to the virtual machine, start the
copy and return connections.
Hyper-V also shows the
beginning of a new machine to count
on time as if they held the
restart (even though it was not).
As every change / off?
Going back to the previous version?
Backup Group I created again
- does not help.

"We are looking for what is
the procedure for checking why
the DPM wants
to do only
offline backup"
Yes that is why I asked what do you see in your "Windows Server Backup" from the Hyper-V host. Did
you do an update at the Hyper-V Hosts? Could you update the Hyper-V integration tools in your Virtual Machine?
What guest system is used in your windows virtual machine? If there a Windows Server 2008 R2 (with installed SP1) or a windows server 2012 you should try to update the integration tools at this machine first. When updated is done, try to backup online again.

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!

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.

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

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 crashes during tape backup for a specific server

Hi Community,
A customer of ours is experiencing an issue with DPM crashing after a period of time when backing up a large protection group to tape.
Customer is running DPM 2012 R2 URE 5
Upon looking in the DPM Logs, we see the following error, immediately prior to the system crashing.

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
