File Share backup job failed Case #04960634

[Karol.k]

Hello.
I am user to Veeam Backup & Replication Community Edition software . So far i used V10 but recently installed V11. One of the shared file tasks stopped working after the change. Error Message :

12.08.2021 13:45:36 :: Error: Agent: Failed to process method {NasMaster.CreateBackupProcessor}: The request could not be performed because of an I/O device error.

A brief description of the configuration.
One of the network shares is backed up from a virtual file server to another physical machine. Physical machines are fujitsu. I did an agent update on veeam recommended machines. I also did a manual update of the agent to version 5.0.0.4301. Additionally installed Fujitsu Plug-In for Veeam Backup & Replication.
Any ideas ?

Best regards.
Karol

Hello Karol,

Can you please clarify is that a nas backup job (file level backup) or an agent backup job (image level backup)? Thanks!

It is file level backup.
Thanks for the quick reply.

Karol,

Can you please try to manually create/upload file to the affected file share and let us know the results? Thank you!

Before I wrote the post, I already tested it. The network share is functioning normally. I can copy files there or create new ones there. I even tested several network shares on different physical machines.

I'm closing the case. I managed to fix the problem. Details: deleted the task -> deleted the server from the "file server" tab -> deleted from the server from "microsoft windows". Then I added it again. I created a new task which ended with success.
