Glad I stumbled across this thread. I may be having this issue.

I didn't see an answer to the original question. Is KB1985 included in v9.5U2?

What errors would I be seeing if I am having this issue?

How about:
Failed to compact full backup file Error: Agent: Failed to process method {Transform.CompileFIB}: An unexpected network error occurred. Failed to read data from the file
Failed to generate points Error: Agent: Failed to process method {Transform.CompileFIB}: An unexpected network error occurred. Failed to read data from the file
Failed to compact full backup file Error: Agent: Failed to process method {Transform.CompileFIB}: bad allocation
Failed to generate points Error: Agent: Failed to process method {Transform.CompileFIB}: bad allocation

All where generated during a clean cycle...

This appears to be also breaking compacts similar to this thread:
https://forums.veeam.com/cloud-connect-backup-f43/back-copy-jobs-randomly-stop-compacting-t40420.html
I've had a few .VBK files stop compacting. They seem to be related to similar errors, meaning I'll see some of the above errors, then the backup copy jobs will stop attempting to compacting. I have the work-around fix, but it's a real nuisance.

Thanks,

Robert

I can't answer for Veeam, but what I have picked up on is that Veeam don't want to issue workaround/fixes for an issue in a 3rd party product that has now been fixed by the 3rd party.
So, when kb1985 came out, there was no fix from Dell/EMC for the issue.
We now know that DDOS v6.0.1.10 resolves the issue that Veeam issued the fix for, so Veeam can [quite rightly] say "install the Dell/EMC firmware update to resolve the issue".

The issue only affects users running DDOS 6 (lower than v6.0.1.10), according the Dell/EMC ETA 498457 (top Dell/EMC Support Searching: use the Product "Data Domain OS" or "DDOS" rather than your actual Data Domain appliance when searching, and you will find the actual notes and firmware you need).

DDOS 6 is still not ratified by EMC as an "EMC Data Domain Target Code" version yet, so you are getting ahead of the support curve installing it (I went for it based on the level of integration that Veeam has with DDOS 6, and the enhanced performance). So if you are running DDOS 6, then upgrading to the latest release isn't altering your support standing with Dell/EMC.

In fact, all previous releases of DDOS 6 have been deprecated on the Dell/EMC support site, if you try to download them: they link you directly to v6.0.1.10 now.

So, if you are a Data Domain user running DDOS 6, then you really should upgrade to v6.0.1.10 at your earliest opportunity.
This also makes the need for a Veeam workaround fix redundant.

Note: I've read some other Dell/EMC support articles that are referencing v6.1 code, so expect another minor upgrade release for DDOS 6 sometime soon[ish] :)

Hi Robert, Lewis is correct, if you're seeing the same issue, the only way to avoid it is to install the mentioned DD OS update, since the hotfix described in Veeam KB1985 doesn't address it. We supposed that adding some additional checks/file closings would work around the issue in DD OS, however it didn't.

To verify whether you're seeing this very issue, please contact either Veeam or Dell/EMC support.

But to answer the original question, KB1985 (bug ID 95715) is in fact a part of 9.5U2, because EMC suggested to use the approach implemented in the original fix as the best practice. Hopefully this will prevent future issues as they update or refactor DD OS code.
