OLVM Backup Error #241: Failed to Send Network Data

Elias Blackwood

Hi everyone! 👋

I’m having an issue with OLVM VM backups. The job fails with error code #241 when I try changing to a different network segment for transmission.
The error message says: “Failed to send network data”.

Has anyone faced this before? Any tips on what could be causing it or how to fix it?

Thanks in advance! 🙏

Hi Elias,

It looks like the error is happening because the VM used for backup has multiple network cards, which can interfere with the transmission network.

To fix this, follow these steps:

Go to Backup > Backup Strategies > Transmission Strategy > Transmission Network.

Change the transmission network when creating a new VM backup job.

Once the network is updated, try running the backup again.

That should solve the issue! Let me know if you need any further help. 🙂
