NFC storage connections

Post by Peejay62 »

Hi,

though not the preferred method, we use NBD for some backups. Due to a problem on some of our esx machines (faulty / buggy firmware causing NFC storage connections to become unavailable) NBD backups fail. I have tried switching over to hotadd by assigning a proxy to the job capable of hotadd. The hotadd job also fails with the NFC connection. I am not able to switch over to SAN mode, so I cannot try if that works. I wonder, is the NFC connection needed anyway, no matter the transport mode? I guess it's being used to pull in the vmx file? Is there a way to bypass setting up that NFC connection (at least in hotadd mode (or san)) and make a backup. I know the problem is not caused by Veeam, but Veeam suffers of it. Right now I am unable te take backups of the machines running on those faulty machines. My sla's are under heavy pressure right now..
Any suggestions are welcome,

Thanks, Peter

Hi Peter,
NFC connection will always be used to grab the VM metadata ( VMX files etc ) - no matter what you use for the transport of the VMDK blocks.

Hi Chris,

ok, suspected that. We have a kind of SPOF here then.. I am experiencing it right now, unable to backup some machines. There should be an alternative way to grab the metadata i wish..

the problem is that you can't hotadd a VMX file & VADP wont allow us to grab the VMX files via direct SAN. The ammount of traffic we pull over NFC for the metadata is pretty small -are you not able to browse the datastores / download files from those hosts? that uses the same protocol.
