Mar 27, 2024 · I wanted to share some insights about our experience using NBD as a transmission method, as we encountered poor performance while currently implementing Veeam. We primarily rely on Storage Snapshots, but some of our ESXi hosts utilize local storage. We aimed to avoid using Proxy Appliances.

Sep 6, 2019 · With Direct Storage mode we got between 250 and 450MB/s processing speed and with Automatic (NBD) mode we got between 1 and 2GB/s. This isn't bad, but based on the Veeam architecture recommendations we would expect that the physical proxies would be much faster than the NDB mode.

Dec 3, 2015 · Used Diskpart to clear the read-only flags, but it doesn't help, restore still happens using NBD. All my VM's are thick provisioned and backup does work over SAN.

Apr 5, 2011 · When using NBD mode "target" isn't just referring to the target storage itself, but rather then speed of writing to the target host which includes the speed of sending data to the management interface on the ESXi host.

Mar 11, 2013 · Use Network (NBD) mode setting on Source Backup Proxy as opposed to Appliance (hotadd) mode for your backup and/or replication jobs in Veeam. Our backup will be on a dell hardware server with local storage (veeam install and large raid), no other device.

Dec 16, 2010 · What transport mode for replication VBR is using now? Do you see the [hotadd] or [nbd] tag next to the target proxy server name in the VM processing log? This topic contains more relevant info. Please take a look. Thanks.

Oct 15, 2021 · I wish to have a warning in the case I choose a specific transport mode (direct san) for my proxy and it has to failover to NBD. How to have a warning in that case?

Jul 26, 2018 · When backing up through the network with the Network Block Device (NBD) transport mode, the FQDN is returned via VMware API for Data Protection (VADP) so the backup proxy server must be able to resolve the FQDN via DNS. Using the hosts file the data transport path can be altered for NBD transfers.

Jun 17, 2015 · David, please look at the job session log, select the particular VM to the left, and look for the transport mode tag reported at the proxy selection step (one of the following: [nbd], [san], [hotadd]). What transport mode is being used by your jobs?

Oct 3, 2012 · I've got an issue with a VM failing over to NBD instead of using hot-add and want to track down why. Thanks
