Manual replica creation of DeDup Volumes

Hi,
we are on the way to update a lot of our file Servers to Windows Server 2012.
DeDup will be enabled on the volumes.
We are going to to backup these voumes via DPM2012SP1.
Now my question: Is it possible to create a Manual replica (for example with the help of USB external drives) for dedup enabled volumes or does the replica creation process have to be triggered from within DPM console so that all data will be transfered
over the Network?
Thanks in advance
regards

Hi,
Unfortumatly, you cannot perform a manual replica creation for a deduped volume in a deduped state, however, you can perform the following, but don't think it would provide you much benefit.
1) On the protected server that has the dedup volume you want to protect, create a dummy folder in the root of the volume.
2) On the DPM Server, protect the dedup volume, except uncheck the dummy folder. Choose to make a manual replica.
3) Copy the contents of the protected volume to the replica volume using any method you choose.
4) Run the mandatory consistency check to make sure the data is equivelent.
5) On the DPM Server, modify the PG and now include the dummy folder - basically uncheck the drive letter and recheck it so DPM will protect the whole volume now.
6) On the protected server, delete the dummy folder.
7) Re-run a new consistency check, and DPM will now protect the volume in a dedup state. This will result in only transfering deduped blocks, and leaving non-dedup blocks intact.
Again, that may not buy you much and may be a waste of time - but give it whirl.

Manual replica creation for Hyper-V

We have several remote hyper-v hosts that we want to move to DPM. The problem is capturing the initial replica since the WAN bandwidth is limited. The procedure for manually creating a file share replica is very straightforward. Is there a TechNet
article on manually creating a replica for a protected Hyper-V guest? Has anyone gone through the process?
Rob

Better outline of the steps to seed replica.
Create the protection group on the DPM server and choose to protect the Hyper-V VM. Choose to manually create the replica in the wizard.
Select the protected VM in the DPM console in the protection view.
Click on the "Click to view details" to get the replica path.
Highlight the row listed and right-click, choose Copy
Paste the path it into notepad or equivalent
Copy the path from C:\ to the end to the clipboard.
This path will be used in the following steps.
Go to a command line
Run psexec -s cmd to get a command shell as the system account
cd "C:\...." where C:\... is the pasted value from the copy above
cd "Virtual Machines"
cd servername where servername is the only subfolder in this directory
Copy the vhdx into this directory.
Rob
EDIT: Note that the path names I've listed above are dependent upon where your files are located. You're path to the VHD will be the same as it is on the physical machine. So if you keep your VHD in D:\myvm\myserver then your DPM path after the
GUID will be Full\D-VOL\myvm\myserver. Copy the VHD into that folder.

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.

Hi,
Not sure what you want help with. Did you fix the underlying volume corruption issue ? For future posts, please limit the scope to a single well defined problem so the community can assist you best.

DPM 2012 R2 UR4 - DPM could not set security permissions on the replica or recovery point volume that was created.

Hi All,
I am running a fresh install of SCDPM 2012 R2 with a protection group that is backing up the 'C:\', Bare Metal and System State of some VMs. If i add any additional servers to the group since the first creation it returns the following error:
Modify protection group: System State & Bare Metal Recovery failed:
Error 419: DPM could not set security permissions on the replica or recovery point volume that was created.
Error details: The process cannot access the file because it is being used by another process
Recommended action: Review the error details, take appropriate action and retry the operation.
If i re-create the whole protection group it works fine.
Could any one advise any further diagnostics I can do to try and locate the reason behind not being able to modify the group after the first creation? I can add new servers to other PGs without any issues.
Thanks in advance,
Dan

If you are protecting any of the system state/BMR protection. Can you stop protection by deleting the older recovery points and then recreate the protection group.
This thread mentions this to be a hardware issue, albeit with less information on what exact hardware issue:

Performing a manual replica of a new protected workload to an existing protection group

I have read much about creating a manual replica of a datasource when
creating a new protection group. Hopefully my question is simple to answer??!! If I
modify an existing Protection Group and select manual replication, will this only apply to the new protected workload in that protection group or will it apply to all the existing protected workloads that are successfully synchronising
also?
I am using DPM 2012 R2.
Thanks
Mark

That will only apply to newly added Datasources.

Trying to Unoptimize a Dedup Volume - Progress stays at 0%

For various reasons, I'm trying to rehydrate my dedup volumes on a recently deployed File Server 2012 R2. There's 5 volumes with dedup turned on - savings ranging from 28% to 49%, and the sizes range from 200GB to 2TB.
I'm running the powershell command:
start-dedupjob -volume "I:" -type unoptimization -priority high
However, after a day, the result of "get-dedupjob" is that the unoptimization type is still running, but shows 0% progress. Shouldn't there be some indications that the job is running? I know the job is going to take awhile, but even
the small volumes aren't moving.
I also ran "get-dedupstats" and compared the before and after "optimizedfiles" category, and that is unchanged as well.
Any ideas?
(Sidenote: prior to running the command, I put the volume folders in the "excluded" folder list so they wouldn't reoptimize after the job was done. Is this right?)
There's no error in the event logs, and in the Dedup log files, it shows that the job has started, and requested memory space, but nothing after that.

I'm seeing this same behavior when running an Unoptimization job - 0% progress made, even though Get-DedupeStatus shows a decreasing number of OptimizedFiles and a decrease in SavedSapce. I thought the job was "broken" when I saw it at first, so
I stopped the job and ran it again. It seems like Get-DedupStatus is a half decent method of tracking progress, but this job seems to take a VERY long time to complete.
Just posting this to stay informed of any future updates on the issue, if any... not trying to piggy-back on the post requesting help.

The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR.

Hi!
I recently took over management of a Windows 2003 domain that had only one domain controller. I was building a second DC for redundancy and discovered that the SYSVOL share on the original DC is in "JRNL_WRAP_ERROR" after the SYSVOL and NETLOGON
share would not create on the new DC. This error goes back as far as the log goes back so I don't know how long it has been in this state.
The message in the event log states to enable "Enable Journal Wrap Automatic Restore" but I found a KB article that says to use the BurFlags key instead. http://support.microsoft.com/kb/290762
Should I run an authoritative restore since I don't have another domain controller with a good SYSVOL?

The automatic restore process AFAIK will initiate a D2 restore. And if
there's no other DC, sysvol might be gone.
I really would prefer to have control - this means I would do a D4.
Absolutely I would :)

Event ID - 13568 The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR.

We had a major storm over the weekend which caused an unexpected shutdown.
I am having an issue with one of my domain controller with Event ID 13568
The domain controller which is running Windows Server 2012 was added successfully just a couple of days ago.
I do not have a full backup of the server yet.
It only has a GC role on it.
What are the things I should look out for before I attempt to Enable Journal Wrap Automatic Restore and set it to 1?
Would it be safer to just demote the server and start from scratch?
Thank you all for reading!

Choose replica creation method not available

Hello,
when I create a protection group for client (desktop, laptop), the 'Choose replica method' does'nt appear in the wizard.
Is there a way to choose a replica method with Clients ?
Thanks in advance,
Jerome

Hi,
No - Client protection has a different workflow and is not conducive to manual replica load. Clients initiate the initial synchronization and if you tried to do it manually, would have likelihood of file copy collisions.

Deduped Folder - Initial Replica creation fails

Following scenario;
File-Server is a 2012R2 Standard box, having it's files stored on an ISCSI attached NTFS formatted drive with deduplication turned on. DFS-R is also active on the volume.
DPM is a Windows Server 2008R2 Server, with DPM 2012R2 running on it.
Most replica's are created ok, but this one fails to create an initial replica.
Is there some limitation for DPM in this scenario? Do I need to install DPM on a 2012R2 box?
Please visit http://www.bleumer.eu

Yes, upgrade your Server to Server 2012 R2.
