Asynchronous request operation failed with synology SMB backup target

if it works with it off then I would leave it off and contact Support to open a ticket to see if they can explain why when turned on it starts failing.

Hi @tastyratz ,

I’ve found this interesting video: 

Maybe you have to verify your Veeam Backup Server and Proxy configuration

Thanks! That looks like a great video/tutorial.

Unfortunately, it doesn’t -quite- apply to me here.

I’m not using B&R, I’m using the windows agents with their own managed jobs to backup directly to the Synology.

I’m also using this to backup important physical machines so I can’t configure multiple nic’s and vmxnets.

That means in essence the devices with the error should only ever be communicating out over a single nic. It’s not optimized for them to maximize throughput so I am less worried about multiple nic’s for example.

Sadly, I have to disable multichannel on the Synology across the board where it helps in other areas to allow these physical agent backups to complete.

Hi there,

solution for me was to limit the maximum concurrent tasks to 1 of the synology repository to avoid that error. Hope it helps.

Best regards.
