DPM - DPM protection 2012r2

I have two dpm2012 r2 servers both running on windows server 2012 r2. They are at different data centers connected with a 100m point to point with latency <10ms.
Lets call them dpm01 and dpm02
dpm01 is at datacenter 1 fw disabled
^
100mbit currently zero firewall/filter rules in place
v
dpm02 is at datacenter 2 fw disabled.
dpm01 can backup dpm02 and its protected datasources without issue.
dpm02 errors when trying to attach dpm01 with error:
DPM could not connect to the Service Control Manager on these servers:
dpm01 (ID: 33221)
running sc \\dpm01 query is successfull
running sc \\dpm01 query dpmra is successfull
ping dpm01 is working no issue.
both forward and reverse lookup zones have entries for both dpm servers, ping and ping -r resolves correctly.
I just cant figure out why dpm02 refuses to connect to dpm01.

setdpmserver.exe doesnt appear to exist on either server.
Also, I am an idiot. I was accepting the auto-typed computer name which happend to be nearly identical except for one character while testing using the correct name that i manually typed.
All works just fine, sorry for the trouble.

DPM 2010; migrated DPM protection group to new storage pool ; data on source disk is not expiring

I am running DPM 2010 with 4 storage pool disks. 2 are iSCSI; 1 is SAS; the fourth, also iSCSI, was recently deployed to replace the SAS storage pool disk.
(1) iSCSI
(2) iSCSI
(3) SAS - Source
(4) iSCSI - Destination
Initially we tried to migrate the entire data source (3) to the new iSCSI storage pool disk destination (4). This failed
Set-ProtectionGroup: The allocation of disk space for storage pool volume failed because there is not enough unallocated disk space in the storage pool (ID: 358). (Sorry, I was not allowed to attach an image).
We believe the source disk previously created dynamic links to the long-term retention device (tape) which resulted in exceeding the available space on the new destination iSCSI storage pool disk. The source storage pool disk was totaling ~2.5TB, but needed
~9TB for the destination.
Instead I've tried to migrate the DPM protection group. The migration was successful. I followed the procedure outlined here
"Microsoft DPM 2012 Sp1 – How To Migrate Data Source using MigrateDatasourceDataFromDPM by ICTtechie" (Sorry, I was not allowed to include a link).
My understanding / expectation was that the data on the source disk would expire within 5 days (as this is our retention time set for disk replication); instead data started to expire from the other 2 iSCSI (1), (2) storage pool disks.
What am I missing here?
Thanks

DPM Protection Agent Communication Error

We get the following error sporadically, and it seems to always deal with an Exchange Server service stealing the DPMRA port. Is there any way to get this to stop. We have to put the mailbox server in 2010 into DAG maintenance and restart services. This
is not optimal. The below error is what we receive. Seems to be the Microsoft Exchange Replication Service:
DPM failed to communicate with servername because of a communication error with the protection agent. (ID 53 Details: Server execution failed (0x80080005))
We run DPM 2012
Thanks

Hi,
you can tell DPM to use a different port on that exchange server:

DPM 2012 R2 Repoting Protection Status as OK but no replica exists for the volume

2012R2 server running 2012R2 DPM. I am using LeftHand SAN as my DPM disks for storing backups. Our production SAN is an EMC VNX5300. I have created a mount point of a LUN and attached it to the DPM server. I have attached a snapshot to the mount point. When
I brought the volume online in Disk Management, it assigned it a drive letter. I removed the drive letter and connected it to a mount point in an empty folder in C:\ActiveVolumes. I am able to browse the folder and look at data in the folder without issue
(except having to elevate for some of the folders when browsing through GUI). In DPM, I created a new protection group. I added the mount point path (C:\ActiveVolumes\MyMountPoint) as a member of the PG. I walked through the wizard and configured my short
term and long term protection options as I have done for other jobs. I had it create the group. At the end of the process, it reported success. Based on having done this with other mount points in similar ways, I was expecting the volume to spend some hours
creating its replica as it is multiple hundreds of gig in size. After less than 15 minutes, it was sitting there with a Green OK display for Protection Status. That seemed entirely to quick so I started to investigate. When I tried to create do anything, it
failed. I looked in Monitoring/Failed jobs for yesterday and today. There was a failed job for the PG that said as follows:
Type: Replica creation
Status: Failed
Description: The Operation failed since DPM was unable to access the file/folder
\\?\Volume{GUID}\Company\Logs\Cleanup\filename.txt on dpm01.domain.pri. This could be due to the file/folder being corrupt or the file system on the volume being corrupt. (ID 2036 Details:
The file or directory is corrupted and unreadable (0x80070570))
There is a second error stating that No recovery point was created, either because synchronization has not occurred since the last recovery point was created, or because no changes were found during synchronization. (ID 208)
When I check the file in question on the original source, it is fine. When I connect to the mount point on the dpm server, browsing to the location, I find that the file says it is indeed corrupt. I will open a call with EMC as well, but it is a little concerning
that a single file can prevent a whole replica from being created. I also tried deleting the corrupt file and tried to synchronize again and it failed on another file in the same folder.
Some additional stuff I noticed as different:
In PG setup wizard, when expanding the DPM server under available members, after a few minutes, I get the following error:
"DPM is unable to enumerate contents in <longalphanumericstring> on the protected computer dpm01.domain.pri. Recycle Bin, System Volume Information folder, non-NTFS volumes, DFS links, CDs Quorum Disk (for cluster) and other removable media cannot
be protected. (ID:38)"
Followed by the following:
"The database of this DPM server is located on a remote instance of SQL server.
To protect the database of this DPM server, you must install a protection agent on the computer running the remote instance of SQL server. After the protection agent is installed, open this wizard, navigate tot eh remote instance of SQL server, and select
the DPM database for protection.
Production server name: dpm01.domain.pri
DPM SQL DB name: MSSQLSERVER
DPM Protection agent: Not Installed"
The above is inaccurate because I am running the SQL on the same machine as my DPM server in the default SQL instance name. I have gotten both of the above errors before when trying to backup other mount points but I was able to back up those mount points
without issue.
I also noticed a difference since I created my first mount point backup. I created two folders on the root of the C: drive. ActiveVolumes and StaticVolumes. I had attached mount points under StaticVolumes previously (c:\staticvolumes\imagefolder1, etc.)
and was able to back those up without issue. When I was configuring that one, it allowed me to select to backup StaticVolumes and then it gave me a warning about mount points and did I want to back those up to. To which I replied yes, back them up. When I
was configuring this one, backing up ActiveVolumes was not an option, only the mount point below it. And it never gave me the warning about mount points. I don't know if this has anything to do with this problem.
Any assistance you can provide on figuring out why this isn't working would be much appreciated. I tried deleting the PG and starting over and got the same results. I am at a loss for how to back this up right now.

What is the best way of creating a one-time backup using DPM 2012R2?

Hello,
Due to some severe tape issues, we have lost a lot of our long-term storage data.
I schedule a recovery point on our servers every Friday, once a week. We retain this data for the 64 weeks (the maximum amount of versions DPM allows.)
Management needs me to put one recovery point from each month to tape (preferably from the beginning of each month.)
From the DPM console, I have been manually searching each server and running a recovery job from each "short term" recovery point we still have in the system.   I am recovering this data to a large disk array that I'm using as a staging
area. My intention is to take this data and put it onto tape using DPM and leave it there forever (20 years.)
Since the space on the array is limited, I can only recover a few months at a time before having to delete the recoevered data to make way for the next group.
The way DPM works it seems you must have a protection group for every backup job you run; so if I have to repeat this process 8 times, I'll end up with 8 different protection groups all assigned to the host running the staging array. NOTE:
the host running the staging array will be wiped in the near future.
What would be the best method to carry this task out ?
This forum post is similar, but doesn't address all these additional groups created:

Any assistance would be welcome!
Matthew J. Fazio

Hi,
What you can do is protect the staging server by using a single share - lets call it STAGING for simplicity.
Perform your first set a restores and restore to the staging share, you can create meaningful subdirectories one for each data source you are restoring.
Now protect the STAGING share using DPM - protect using long term to tape only, Frequency yearly, and set retention policy for 20 years.
Perform an ad-hoc backup (right-click the data source and create recovery point to tape)
When that completes, delete the sub-directories under the staging share and then repeat the process of restoring more data then backing up the same share.  When you are all done, you can remove the protection group, but maintain the tape backups
so they will be available for restores.

DPM 2012 R2: Remove Recovery Points

Missing Recoverable Items DPM 2012R2

DPM Protection Group shows that a specific folder on a drive being backed up is being backed up. No alerts that the protection group is failing. (all green) However the specific folder does not show up when trying to restore it. All files and
folders are available for restore above it. Any clues to, one, why this may be happening, and two, how to get the files and this folder to be backed up? (not listed in exception rules)
Thanks in advance.

Interesting, I did a restore from the directory above and the 'Archive" directory did restore. I wouldn't say this is a major bug, but something that should be fixed.

DPM 2012 Protection Agent Connection Failure

I was successfully protecting a Windows Server 2008 R2 Ent. Server with my M.S. System Center 2012 R2 DPM R2 Server until today. The only changes I know about are the fact that this 2008 server was promoted to a domain controller today using the same
name and I.P. Address. It appears that the DCPromo process has broken DPM protection somehow. Is it true that a "dcpromo" of a protected server can cause DPM Agent failures? If so what is the preferred method to fix this problem.
I'm hoping that I don't really have to stop and clean up the current protection for this server and then start over again. Does anyone have a solution for this problem? Here are the errors I'm getting:
Affected area: ServerName.DomainName
Occurred since: 1/13/2015 8:30:02 AM
Description: The DPM protection agent on ServerName.DomainName could not be contacted. Subsequent protection activities for this computer may fail if the connection is not established. The attempted contact failed for the following reason: (ID 3122)
The protection agent operation failed because it could not access the protection agent on ServerName.DomainName. ServerName.DomainName may be running DPM, or the DPM protection agent may have been installed by another DPM server. (ID 302 Details: )
More information
Recommended action: Uninstall DPM or the DPM protection agent from ServerName.DomainName and install the DPM protection agent again from the computer that you want to use to protect the computer.
On the Agents tab in the Management task area, check the status of the agent.
Resolution: To dismiss the alert, click below
Inactivate
Protection agent version: 4.2.1254.0
Error: Data Protection Manager Error ID: 270
The agent operation failed on ServerName.DomainName because DPM could not communicate with the DPM protection agent. The computer may be protected by another DPM server, or the protection agent may have been uninstalled on the protected computer.
If ServerName.DomainName is a workgroup server, the password for the DPM user account could have been changed or may have expired.
Recommended action: Check the following to troubleshoot this issue:
1) If the agent is not installed on ServerName.DomainName, run DpmAgentInstaller.exe with this DPM computer as a parameter. For details, see the DPM Deployment Guide.
2) To attach the computer correctly to this DPM server, run the SetDpmServer tool with the -Add option on the protected computer.
3) If the computer is protected by another DPM server, or if the protection agent has been uninstalled, remove the protected data sources on this computer from active protection. Then, remove the entry of this computer from the Agents tab in the Management
task area.
4) If ServerName.DomainName is a workgroup server, run SetDpmServer with the -UpdatePassword flag on the protected computer and Update-NonDomainServerInfo.ps1 on the DPM server to update the password.
5) If the DPM server and the protected computer are not in the same domain, ensure that there is a two-way trust setup between the two domains.
Note: I tried running the setdpmserver tool but got the following message:
SetDpmServer failed with errorcode =0x80070534, error says: No mapping between account names and security IDs was done.
I also tried the attach agents option but DPM tells me that there is already an agent installed.
I also tried to manually start the DPMRA service on the client but it fails with error code 1168.
Any helpfull information would be greatly appreciated.
Thank you,
MPeterson

Hi,
Try the following:
Uninstall the agent from the protected computer.
Restart the computer.
Install the DPM-agent manually.
Re run the SetDPMServer command.
Try start the service.
If the problem still exist, please look into the following steps:
Verify the COM+ permissions for the DPM agent on the protected server. There could be a mismatch in the permissions:
Click START / Administrative Tools / Component Services
Expand Component Services / Computers / My Computer / DCOM Config
Right click on the "DPM RA Services" and choose properties. Verify that under the Security tab / Launch and Activation Permissions you got Customize marked, click the "Edit..." button in the ACL you should see the computer account for
your DPM server.
If it's not present add it and mark all allow boxes and try to start the service again.
You should also verify that your DPM-server computer account is a member of these two local security groups on the protected server:
DPMRADCOMTrustedMachines
DPMRADmTrustedMachines

VM Protection running on Hyper-V 2012 R2 with DPM 2010

Hi everyone,
We recently setup a new Hyper-V 2012 R2 server hosting virtual machine running with a Win2012 R2 server OS and 2008R2 standard Edition
Our backup solution is still running DPM 2010.
As I understand from the DPM Protection Support Matrix, You can only protect virtual machine running on a hyper-v server under Windows 2012 R2 OS with DPM 2012 R2. Isn't there possible any walkaround to have the vm protection working on dpm2010?
Otherwise, if we choose to protect the VM at guest level instead of host-level, is DPM able to perform the recovery point?
For instance, we've got a VM running a SQL database. We would like specifically to back up that SQL database running on that virtual machine.Is DPM able to perfom that job?
Regards,
Evan

Hi,
To remain in a supported configuration you need to a DPM 2012 R2 server to protect the Windows 2012 R2 hyper-v server. Unfortunately, the path to get there from DPM 2012 is not an easy one.
Upgrade steps.

DPM encountered an error while reading from the recovery point used for recovery.

Hi Guys I'm getting this error:
DPM encountered an error while reading from the recovery point used for recovery. Either the recovery point no longer exists or, if you
selected a share for recovery, the path to its contents is missing from the recovery point. (265)
The DPM Server is on Windows 2012 DPM is 2012R2 4.2.1273.0
The Server being backed up is 2012 R2 with DPM Agent 4.2.1273.0
The Server has 3 Data Volumes (C: Drive) and D and E its the D and E drive that i get this error if i try and recover data from DPM. the C Drive is fine. the D and E Drive are different
in that 1 De-dupe is enabled and 2 the Shadow Copies for these Volumes are stored on separate Disks F and G respectively.
I've removed the Protection from drives D and E and reinstated it but every recovery point created
brings up the same error message. I'm not sure where to go next do I need to Protect the Disks that have the Shadow copies on also? Many thanks in advance Gordon.

Hi,
It seems you are in a configuration where the Windows 2012 based DPM server does not understand how to read Windows 2012 R2 Dedup data structure which is what the DPM replica volume is.
See the DPM supported and unsupported scenarios
here under the deduplication issues section.
We have a fix in DPM2012 R2 UR5 that will protect the Windows 2012 R2 dedup volume in a non-dedup state on the DPM Server, but unfortunately that will not allow previous recovery points to be read.
KB3021791-Description of Update Rollup 5 for System Center 2012 R2 Data Protection Manager
Backup job for dedupe-enabled volume on Windows 2012 R2 fails. For example, Data Protection Manager backup might fail for following setup:
Data Protection Manager2012 R2 is installed on Windows Server 2012.
Data Protection Manager is protecting a dedupe-enabled volume on Windows Server 2012 R2.
This also applied to restores as the above was for D2D2T backup that may fail as it needs to read the recovery point to back it up to tape.

Upgrading DPM 2010UR5 Agent to DPM2012R2UR1 Agent

Hi all,
we are running DPM 2010UR5 Protection Agent on a Win2008R2 Server with Exchange 2010.
I have to upgrade the Agent in order to move backups to DPM 2012R2 UR1.Previously I wanted to uninstall the old Agent .
Unfortunately there is no option in Control Center/Software to uninstall the Agent - it is just listed under Updates.
Because of that I tried:
"Msiexec /x {72BF00D8-53E0-1539-F523-4347082BCC11}" an
"Msiexec /x {72BF00D8-53E0-1539-F523-4347082BCC11} /qn /REBOOT=ReallySupress"
But i did not work either.
So, what would be a good way to upgrade DPM 2010UR5 Agent to DPM 2012R2 UR1 Agent?
Thanks in advane
regards

Can you try something like this?
$reg = Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*" | ? {$_.DisplayName -ne $null -and $_.DisplayName -like "*DPM Protection Agent*"}
if ($reg -ne $null)
$pkey = $reg.PSChildName
cmd.exe /q /c "start /wait msiexec /x $pkey /quiet"
Thanks.
BTW, how can you determine that the agent is still installed when you can't see it on "Add/Remove programs" window?

Report to return all servers under DPM

Hi,
I'm tying to create a report to return all servers currently under DPM protection. I have a number of DPM servers and need to report which servers are backed-up by which dpm server.
I'm joining the following tables together [tbl_AM_Server], [tbl_AM_InstalledAgent], [tbl_AM_Agent] but i'm getting more servers coming back than the interface is showing. They may have been servers that were previously removed. This is what my query looks
like:
select distinct s.NetbiosName
from [dbo].[tbl_AM_Server] s
inner join [dbo].[tbl_AM_InstalledAgent] ia
on s.ServerId = ia.ServerId
inner join [dbo].[tbl_AM_Agent] a
on ia.AgentID = a.AgentID
where ia.Deleted = 0
and ia.Enabled = 1
and s.NetbiosName <> (select @@SERVERNAME)
Any help is appreciated.
Paul

Hi,
This should work better.
select distinct s.NetbiosName
from [dbo].[tbl_AM_Server] s
inner join tbl_JM_JobDefinition jd
on s.ServerId = jd.ServerId
where jd.IsDeleted = 0
and s.IsDPM = 0

the message resource is present but the message is not found in the string/message table
Our DPM Server has a 4Gb configured with NicTeaming (SLB - Switch Load Balance), there is no fw between the DPM Server and Protection Servers.
We receive some DCOM errors too:
Level Date and Time Source Event ID Task Category
Error 25-02-2014 10:17:18 Microsoft-Windows-DistributedCOM 10009 None DCOM was unable to communicate with the computer server.contoso.com using any of the configured protocols.
We already uninstalled some agents, cleaning folders/files registry and after installed the agents again and performed setdpmserver -dpmservername <dpmserver>
we can ping, we can traceroute, sc query, net view \\server , nothing is blocked...
in DPM console -> Management -> Agents, when we try to refresh the connection the agent status is always "Attempting connection..." if we close and open DPM console the Agent Status is Unknown.
The version of the Agents is 4.2.1270.0
Is anyone with same problem.
Thanks in advance

Secondary DPM (2012 R2) Issues: synchronising too much data from Primary DPM, persistant consistancy checks, and no dedup support!

I have a Primary DPM server that is protecting various File servers and a Exchange DAG. Everything is working as it should on this server, but I am experiencing constant issues on the secondary DPM protecting these same data sources.
On the primary, two Protection Groups in particular are set up to protect two different volumes on the same file server. Volume D:\ is 46TB in size, with a deduplicated file size of 22TB (actual 39TB) whilst Volume E:\ is 25 TB in size, with a deduplicated
file size of 2.5TB (actual 5.5TB).
Issue 1:
As expected Volume D: was initially replicated to the secondary DPM server at its undeduplicated size ( 39TB), as was Volume E:\ with initial replication to the secondary of 5.5 TB. So when is Microsoft going to support dedup on a secondary DPM ? It
seems daft to support dedup on the Primary DPM which is always more likely to be close to the original datasources on the LAN and not on the secondary DPM which is most likely to be placed offsite on a WAN !
Issue 2:
I have a big issue with the subsequent Synchronizations on the secondary server for E: which seems to transfer almost the full 5.5 TB every day ( I have it set to sync every 24hrs) - although the data is fairly static (i.e.unchanging) on that volume. On
one occasion a Sync continued for over 48 hours for this volume and had transferred over 20GB (according to the DPM console) , until I manually cancelled the job - how is that possible on a volume with only 5.5 TB (UN-deduplicated) ?? What is going on here
- has anyone any ideas?
Issue 3:
Another File server I am protecting on both the Primary & Secondary DPM server - always fails over to a consistency check on the secondary server - usually due to the fact it cannot access a particular file which results in an inconsistent replica .
However the Sync (and subsequent restore point) on the primary DPM server from the original datasource is always completes without any issues. Again, has anyone any clues ?
I do get the impression that the whole Secondary DPM thing is not quite robust enough. I can only assume that as the Primary seems to protect the original datasources ok, that the issue is with the secondary reading the information on the primary DPM.

I tried changing the time of the synchronization, but that didn't help.
Meanwhile, I was working on another unrelated case with Microsoft and so I didn't want to have a second case open at the same time. So I waited for some weeks with no change on this problem. Then, about a day or two before I was finally going to call Microsoft
to open a case (months after the problem had started), the problem suddenly resolved itself, with no input from me! So I don't really know if it was time that fixed it eventually or what. Sorry I can't be of more help.

Memeber server in a domain connected with external trust. The agent operation failed, DPM could not communicate with the DPM agent. Error ID 270

I manually installed the agent on a member server in a domain (domainB) that has an external trust with the domain the DPM 2010 server, mydpmserver.domainA.int, is in.
I pointed the agent on myprotectedserver with setdpmserver -dpmservername mydpmserver.domainA.int
I successfully ran attach-productionserver.ps1 in DPM Management Shell.
When I click refresh in DPM 2010 Administrator Console/Management/Agents I get error id: 270
The agent operation failed on myprotectedserver.domainB.int because DPM could not communicate with the DPM protection agent. The computer may be protected by another DPM server, or the protection agent may have been uninstalled on the protected computer.
If myprotectedserver.domainB.int is a workgroup server, the password for the DPM user account could have been changed or may have expired.
I can ping myprotectedserver.domainB.int from mydpmserver.domainA.int
DPM 2010 backup of the domain_controller.domainB.int works fine.
The application log on myprotectedserver.domainB.int does not show any DPMRA related event logged.
The firewall on myprotectedserver is off.
Computers in domainA and domainB use their own networks connected through a router.
from mydpmserver
net view \\myprotectedserver.domainB.int /all - successfull

from domaincontroller.domainB.int:

Any suggestions on how can I fix this?

Hi
I know this is old but are you still having a problem?
