Error 71 and DFSR writer disappearing

quebecois
Level 3

Hi everyone,

I have a very strange issue on a Windows 2008 R2 Enterprise client with DFSR. For the backup configuration I followed the instructions from this link (medium to large environment): https://support.symantec.com/en_US/article.HOWTO65638.html

The backup works fine for a couple of days (sometimes weeks), but then suddenly I got error 71 on the DFSR job and 69/50 on the Shadow Copy Components (from All Local policy) job as below.

When I check the writers on the client (vssadmin list writers), DFS Replication service writer simply disappeared! Then I have to restart DFS services and after 10 minutes the writer is back and the backup works until the next occurence in a couple of days/weeks.

My environment: Netbackup standard 7.7 (RHEL), Netbackup client 7.7 running on Windows 2008 R2 (same problem occurred before upgrading, on version 7.6.0.3)

Thanks for any support!!

Can you check the event viewer on client machine if it mentions anything about DFSR service/writer getting crashed? What is the status of DFSR service? Does it go down as well?

If the DFSR writer is crashed/hung then you will have to contact Microsoft to understand the behaviour.

Hi SymGuy-IT, thanks for the quick response. Indeed we are getting the error message below on eventviewer whenever this issue occurs:

An unhandled exception was encountered while processing a VSS writer event callback method. The VSS writer infrastructure is in an unstable state. Restart the service or application that hosts the writer.
