EMC DD After upgrade to latest V12 - Error: Failed to call RPC function 'DDBoostFcWriteFile': Failed to open file '
Has anybody encountered this kind of issue?
14:34:35 Failed to pre-process the job Error: Failed to call RPC function 'DDBoostFcWriteFile': Failed to open file 'xxx.vbm_1_tmp'. nothing matched. Err: 5004.
14:34:43 Error: Failed to call RPC function 'DDBoostFcWriteFile': Failed to open file xxx.vbm_1_tmp'. nothing matched. Err: 5004.
This issue seems to be random and not for all backup jobs.
EMC DD is upgraded to latest Veeam supported firmware - 7.11
Case 06196276

Hi,
We have Upgraded our Veeam in 12.0.0.1420 P20230718 Yesterday.
And we have the same behaviour than you.
After the Upgrade I have making Backup/Restore and Replication Test, all was OK.
This Night during our Backup Windows, We had half of our Backup who had Failed with the error :
Failed to pre-process the job Error: Failed to call RPC function 'DDBoostFcWriteFile': Failed to open file 'xxx.vbm_1_tmp'. nothing matched. Err: 5004.
This Morning I have making another Backup Test All was Ok.
So I have run one of our Failed Job and the Job run Fine.
I have Opened a Case : 06259108 (and I have transfered logs)
I hope our Backup will run fine...

Thanks, at least i am not alone with this
So maybe Veeam - can you give some more attention to this issue now?
Weird thing is, that if backups fail at night, even after three retrys, i retry in the morning and all are success now.

You have already uploaded them upon opening a case.
Sure, you can either ask the engineer or use the Talk to a manager button within the support portal to escalate the case.

What DDOS version are you both running?
I have 2 Data Domains with latest V12 patch running on DDOS 7.10 and have not had any issues at all (so far).

Yesterday the Support tell us to change our gateway server or to reboot our Datadomain.
We have reboot our datadomain and our veeam server (who is the gateway server).
This night half of our backup failed with the same error.
We have relaunch failed jobs at 5h00 this morning and they successfully finish.
This night while Jobs failing I have tested the Datadomain connectivity/accessbility and all was alright !
And the CPU/ RAM of our veeam server was at 10%.

First tests with a replaced VeeamDeploymentDll.dll looking good so far.
Hence we only noticed the errors in scheduled jobs, I´ll have to wait for tonights backups to be clear.

Well i still get the same error, not for all jobs, but rather random, also a new error line is showing up:
25.08.2023 18:33:49 :: Unable to apply retention policy: failed to delete backup files Error: Failed to call RPC function 'DDBoostFcWriteFile': Failed to open file '[xxx] xxx:/ka129lis - xxx.vbm_3_tmp'. nothing matched. Err: 5004.

Re: EMC DD After upgrade to latest V12 - Error: Failed to call RPC function 'DDBoostFcWriteFile': Failed to open file '
We have the same issue and have opened a support case (case #06261582).
We restarted our DataDomains, updated to the latest version of DDOS without luck.
For testing we disabled all backup copy jobs and enabled only one to synchronize the restore points with success.
So as next test we changed the maximum concurrent tasks to 1 in the backup repository settings and enabled all jobs and it works. No more errors.
But for now it takes a lot of time to process all jobs.
For us It looks like a resource management problem with the latest patch.
Hope it will help

Hello, As a workaround for users who are experiencing the problem, right-clicking on the repository where you get the error, Gateway server, then using the following gateway servers only option, and choosing a suitable gateway server option will ensure that jobs are completed without any problems.
and you need to perform this operation on all repositroys of your error name. By choosing different gateway servers

Hi,
FYI:
we also ran into DDBoost Error 5004. Veeam Support gives us a fix that seems working (just a single DLL file to replace in a certain directory), but we noticed that when a server rescan occurs the original bugged DLL is restored and the fixing DLL is renamed with prefix "old_12.0.0.1420_".
We have just asked support to investigate this.

Hi,
We have replaced the DLL one week ago and we don't have any issue since.
Hope all of you will find a solution.

Hello!
Just wondering if this hotfix is gonna be available for all the public or a case support is really needed to get it. A public KB would be really appreciated
