I have one environment where I've tried
NBD and it was just as fast (or should I say slow?) as SAN based backups.
They were running at about 50MB/s and I believe the bottleneck is the storage
array where the VMDKs are housed.

Thanks for the clarification
George. The guide says the datastore must be available to the backup host
several times on pgs 17 (diagram) ,23 (Table 2-1) & 24 (Notes). Perhaps
I should have read a bit further on pg 24 “A SAN connection between the
backup host and the datastore is optional if you use the NBD transfer type
or NBDSSL transfer type.”

Hi Jonathan.
You can implement the NetBackup
for VMware solution on any storage that is supported by VMware. If
you have a non-shared storage environment such as NAS or DAS storage, you
can backup your VMs using network based backups. NetBackup implements
this as the NBD transport type. You lose no backup or restore functionality
when implementing this transport type.

Subject: [Veritas-bu] Netbackup for vSphere 4
I was just reading through
the NetBackup for VMware 7.1 Administrator’s Guide and it looks to me
like there are no options to implement this policy type other than at locations
that have shared VM storage (by presenting the luns to the master.) This
seems very strange to me, given that tons of other solutions allow the
backup of .vmdk files across the network without shared storage. Does anyone
know if Symantec plans to change this in the future? We are actively deploying
ESX to the field in small / non-clustered configurations (without shared
storage) and I’m being pressed on why we can’t backup the .VMDKs directly.
