Hi,

I have installed the latest proxmox version 8.0, unfortunately the backup doesn't work. After 5% NFS or SMB cannot respond. This means that the VM is completely busy and Proxmox VE has no connection to the NFS or Samba/Cifs backup.

I did all Upgades on Proxmox but it didn't help.

PVE Version output:

Any suggestions?

Thanks
 
Hi,

This looks like a network issue, did you check the monitor during the backup on the network traffic? What error you see in the syslog in the backup time of the VM 1500?

Can you also post the backup task job?

Code:
unable to activate storage 'Backup-Mo-Fr' - directory '/mnt/pve/Backup-Mo-Fr' does not exist or is unreachable
Can you test by set bandwidth limits in your Proxmox VE node and test the backup (first make sure that the NFS storage is up and running). You can set the bandwidth limit by going to your Proxmox VE node Web UI then Datacenter->Options->Bandwidth Limits.

I got it resolved, there are two subnet for my backup-server and I took the wrong subnet. So the whole traffic went over our pfsense Firewall. :D
My bad, thanks anyways for your time!

Best regards,
Marko
