DPM 2012 R2 - ID 2019 Details: An existing connection was forcibly closed by the remote host (0x80072746)

Almost all of our backups are running and completing fine but we have 4 tape job's that will begin to backup then error out at about the same point all the time with the same Error Details (ID 2019 Details: An existing connection was forcibly closed by the remote host (0x80072746)). All 4 tape job's that fail are on the same 2 clustered servers, but we do have 3 job's on the same server cluster that will complete. Any help would be greatly appreciated, Thanks.

This is a list of our setup:

Single DPM 2012 R2 server running on Windows 2012 R2 Datacenter

2 clustered file servers running Windows 2012 R2 Standard

Data Deduplication is enabled on both file servers

Tape Library is Dell PowerVault TL2000 (LTO5)

Disk storage is Dell PowerVault MD3200 direct attached with about 75TB

Hi,

Same problem here.

Sometimes the backup to tape finished with the error id 2019 and sometimes with 3311.

The specifications are approximatively the same:

DPM 2012 R2 on Windows 2012 R2

Tape Library Dell PowerVault 24T (LTO 4)

Disk Storage EonStor with 10TB

The backup to tape job process 10 servers and the problem appear always on the same server. A Windows 2012 R2 with data deduplication activated. In the past we already had this type of problem, our workaround is to backup the directory in place of the all disk.  In this case we lost the benefit of data deduplication for the backup but it works.  This time it's not possible to apply this workaround because the rehydrated data overtake our backup disk capacity :(

It's the second problem with the backup of deduplicated volume.  The first one reported the backup to disk as failed and force a consistency check.  This problem was solved by Microsoft after 3 months with the last update.

How can I explain to my boss that we must live without backup of critical datas during this lap of time ?  And now another problem to backup to tape....

I seriously investigate other solutions to backup our Datacenter.  Veeam seems to work like a charm with all configuration.Since many years I push to work with the same editor for all the chain of the process, thinking that these guys know the specificity of their product better than others, but it seems that I'm not right.

And please, stop to add a link with "More Information" who redirects to a Page Not Found.  It's very frustrating when you have a problem.  This link never sends me to a existing page regardless the kind of problem.

Thanks

Hi,

I am also experiencing the same issue with backing up a deduped volume. The data deduplication volume backs up to disk without error but then fails when being backed up to tape with the same Error Details (ID 2019 Details: An existing connection was forcibly closed by the remote host (0x80072746)).

nope, but a week of pain un-optimizing everything and needing to run multiple consistency checks, and now recovery volumes that are the size of the replica volumes. (seriously hoping we can shrink those one the retention range passes)

extremely disappointed and tainted. the dedup itself worked wonderfully on our FS but DPM didn't like 2 out of the 4 volumes we enabled dedup.

Hi all,

After the last problem with deduplicated volume for synchronisation (Microsoft take 3 month to resolve it) and now a new one to do the backup to tape we have moved to Veeam and all is working well now.

Sorry Microsoft, I'm a supporter of your products, but let us with problem to do a backup since november (first problem, and now tape problem) is not acceptable.  You must understand that backup is critical and be more responsive on this kind of problem.

I finally found a work around for my environment.  Add DWORD entries with names "ConnectionNoActivityTimeout" and "ConnectionNoActivityTimeoutForNonCCJobs" in path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent" and set the value to 7200 on DPM server.  Now recycle the DPMRA service.  Worked like a charm.

Now, you may be wondering, why did I set the timeout to such a large value?

Well, it was heavy handed, I tried 900 first, and the problem remained.

At 7200 it went away.  A lower value may work just fine in your environments.

Unfortunately support is useless.

We had an open case and below is the "case closure email"

We ended up switching from volume protection to folder protection which means DPM stores its replica in de-duped state.

Hi Andrew,

It was my pleasure to assist you during the troubleshooting of your DPM issue. This refers to Microsoft support case ID (114070811599411).  I am providing you with a summary of the key points of the case for your records. If you have any questions please feel free to call me. You can reach me using the contact information below and referencing the case ID.

 

ISSUE: For  F\: drive on file server ADL-SRV1 tape backup fails with error" ID 2019 Details: An existing connection was forcibly closed by the remote host (0x80072746)"

 

TROUBLESHOOTING: Checked for volume corruption. 

CAUSE: Known issue with DPM 2012 R2 - tape backup of - de-dup volumes (Bug).
 

SOLUTION:  work around:

Run the windows power shell command Start-DedupJob X: Type Scrubbing full ReadOnly   Where X: is drive letter of deduped volume.

 

For DPM replica Perform these steps so that some windows power-shell commands can be ran to detect corruption:

 

IMPORTANT NOTE: DO NOT LEAVE DEDUP ENABLED ON DPM REPLICA VOLUME.

 As per our last discussion, I am closing this support case (114070811599411). The case can be reopened anytime if you have further queries by just dropping an email to me.

Protected Server OS: Windows 2012 R2
DPM Server OS: Windows 2012 R2

exhibits this problem when attempting to tape a disk replica containing a dedupicated volume.

In light of the useless support (see case 114070811599411 above), logging this with MS is pointless.

Our best bet is to pray that this can be fixed in an upcoming rollup.

Since some of these issues aren't directly the fault of DPM itself, it's possible the solution may come in the form of an update rollup for the operating system instead.

Can anyone confirm whether the October 2014 update rollup for Windows Server 2012 R2 KB2995388, containing included fix KB2959146 for stability in Data Deduplication for Windows Server 2012 R2 fixes this problem as well?

October 16th, 2014 1:10pm

My very first test run with KB2995388 installed on the DPM server when taping a replica of a de-duped volume was successful.

Now to see if this success continues during an overnight taping session of same.

Can you confirm your success? because we've got the same issues with tape backups of dedupped data...

I already forwarded your findings to our case at Microsoft, just to see what Microsoft have to say about this..

October 22nd, 2014 9:28am

I'll have to tell you on Monday, this de-duped volume only gets taped once a week on weekends.

October 22nd, 2014 10:46am

from my memory of this issue the first few tape backups after a successful replica creation of a deduped volume worked fine. This issue didn't appear until scheduled dedup optimization jobs ran over the course of a few days as the data changed.

Thanks for reporting back The Fellenator, very keen to hear how it progresses although I wish MS would officially acknowledges this issue.

Has anyone been able to test whether DPM 2012 R2 CU4 resolves this problem?

The release notes for KB3009516 don't mention anything tape or de-dupe related as having been fixed, so I'm not hopeful.

Maybe I should have more faith, or at least, point my prayer mat more towards Redmond?

Has anybody received an update from Microsoft about this issue, by chance? We've been unable to back up our deduplicated volumes for quite some time. Unfortunately removing deduplication is not an option and the workarounds don't work.

Hi @all,

originally, we had one file server with all data on it (deduplicated volume). Then all of a sudden, the error appeared.

After testing several tips without any effort we have moved some data to a new server with a deduplicated volume. Now backup runs smoothly on both Servers without any further errors. Seems as if the amount of data is also crucial for this problem.

January 8th, 2015 12:00pm

I noticed that our latest tape backup went through without failure, but having checked, the data has written over without the de-deduplication savings. So a volume that is on the disk backup as 500GB is going to tape as 700GB+

Very strange.

Installed the update, rebooted the server, deployed the agent updates, rebooted all of those too... For nothing... Thanks for keeping us occupied MS... hope we get a real solution soon.

Back to surfing and googling for alternative solutions for me... Glad I've got my backup to disk, hope the building never burns down...

Hi,

I have talked to MSFT in the context of another error (console crashes after RU5 installation, none of the repair advices worked) and he told me that this is still a known bug but he cannot say if there will be a hotfix or if we have to use the workaround given by nardonov.

He told me that it could help to deactivate deduplication, create a full backup without dedup and then reactivate dedup - after RU5.

This is of course no easy workaround. I don't know if our server can handle data without dedup or if I have to extend the volume...

In the meantime I will try the PowerShell command.

April 22nd, 2015 8:24am

Has anybody been able to confirm whether UR6 for DPM 2012 R2 resolves this?

yes, the workaround suggested involves checking (and repairing) the integrity of the dedupe chunkstore of the REPLICA.  Once this has been completed, the important note is to ensure no actual de-dupe passes are run on the replica itself by the DPM server on an ongoing basis, so the idea is to ensure all de-dupe related tasks for the volume are disabled.  You DONT want it to run de-dupe real-time, and you DONT want it to run a scheduled de-dupe pass either.  In my opinion whats happening is that we're basically running a fancy version of chkdsk /f on the volume involved to repair logical corruption.  Immediately after which you should run a DPM consistency check of the volume against the protected server's volume to ensure the contents is made to re-match exactly afterwards.
May 28th, 2015 4:04am

Even with Win2012R2, DPM2012R2 with UR6, and the protected server also being Win2012R2 and all fully patched, we're still getting the same error about an hour or so in (155GB) when taping the replica (750GB):

We're also continuing to get the same issue on the same operating systems and DPM patching levels as you.  It seems that I can occasionally get it to work if I do a consistency check and then re-run the tape job but if it does work, it will be only once before it goes back to the errors again.


June 3rd, 2015 4:10pm

Hi,

for us, the following PowerShell command did the trick:

Start-DedupJob -Volume <Drive letter>: -Type Scrubbing

After that, DPM is able to fully backup all data to tape again. I cannot say whether UR6 does the same thing or makes some corrections concerning this error.

You have to wait for the job to complete if you did not already do that ;-)
June 11th, 2015 7:28am

No, on the protected server.

What seems strange to me is that backing up the protected server to disk works without any problems, only backing up to tape causes this issue. What is the difference here? Does data have to be "unduplicated" before writing it to tape?

The job takes only 10 Seconds and is truly done on protected server before take backup starts.

I think data have to be "unduplicated" before writing it to tape. But "unduplicating" does never start for tape backup.

I am definitely still having this error in my environment. I haven't been able to fully test the "fixes" in UR5 because it broke deduplication on my backups for a FS cluster (which was an exceptionally painful support ticket). I was finally able to install UR6, but the tape backup issue persists.

June 22nd, 2015 11:04am

I have found a workaround for our environment.

We have a protection group which includes 4 servers for file backup. Two of these servers are 21012r2 with dedup. Only one of them has this problem which i have discriped above. It is his volume D:\

First i have tested the volume C:\ form the same problematic server and tape backup was no problem. Volume C:\ has no dedup enabled. Now I have removed this problematic server volume D:\ complete from the protection group and keeped all data. Next i have changed the protection group again an choose only all first level subfolders from the volume D:\ but not the root D:\ itself. Now i see all subfolders from volume D:\ in the protection group and backup on tape is NO PROBLEM! In an first test i have choosen only one subfolder of volume D:\

Maybe is there a problem with the folder "System Volume Information" which now is not included?

Could anyone do a test like me and reporting here?

HB - I've seen this workaround mentioned before (and have seen it as a "solution" for Microsoft support cases on the issue). The problem with this is that since you're no longer backing up a volume, the backup isn't deduplicated. While this may work for environments with extra space to allocate toward backups, it most certainly will not in mine. I've had long-fought battles with MS already regarding backups that were being taken as non-optimized after the functionality was broken in UR5.

For what it's worth, the scrubbing dedup job on the source data did NOT fix this issue in my environment.

I think a backup on tape could never be deduplicated all files are wriiten nativ on tape and thats the reason why backup on tape is failing. While starting backup for a dedup volume anything takes too long time for "undedup" and reaches a timeout after round 5 minutes. In different environments is the number of files involved by dedup different. So in some cases backup works fine and other scenarios backup failed.

I had the same Problem. After installing DPM 2012 R2 UR6 on the DPM and file server and KB2995388 on the file server, I removed the datasource from the DPM Protection Group, started the scrubbing Job on the file Server and readded the Datasource. Now the tape backup works properly.
July 28th, 2015 3:14am

I have tried the same in the past and found that the tape jobs may work for a while but they eventually experience the same issues again.

Maybe UR7 will help, though I see no mention of any similar issue in the list of fixes.
