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.

Scott Chapman Senior Technical Specialist Storage and Database Administration ICBC - Victoria Ph: 250.414.7650 Cell: 250.213.9295 From: veritas-bu-boun...@mailman.eng.auburn.edu [ mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Martin, Jonathan Sent: Monday, May 02, 2011 10:39 AM To: George Winter; nbu Subject: Re: [Veritas-bu] Netbackup for vSphere 4 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.” -Jonathan From: George Winter [mailto:george_win...@symantec.com] Sent: Monday, May 02, 2011 1:14 PM To: Martin, Jonathan; nbu Subject: RE: [Veritas-bu] Netbackup for vSphere 4 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. -George Winter Symantec Corporation From: veritas-bu-boun...@mailman.eng.auburn.edu [ mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Martin, Jonathan Sent: Monday, May 02, 2011 8:29 AM To: nbu 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. -Jonathan This email and any attachments are intended only for the named recipient and may contain confidential and/or privileged material.
