I guess I am confused here. If I use Veeam to backup VMs that reside on the Tintri that have Tintri snapshots I still get long commits that can cause brief outages. This may be an issue with the secondary storage I am using, but if I were working off of a storage snapshot from the beginning wouldn't I not need to worry about commits on a running VM? When I do a Tintri snapshot that quiesces the VM it stay open for only the briefest possible time. If Veeam could backup from a Tintri snapshot that happens 15 minutes before the job starts then we would not impact production VMs at all from a VMware snapshot perspective. If I am wrong please help me understand.
vClintWyckoff wrote:@Loren / @Daltorio - @Geoff's correct. Yes you can offload the Snapshot from the Hypervisor through the use of the VAAI NAS Primitives - the Tintri VAAI plugin needs to be present on your ESX hosts (You download this off of your Tintri Support Portal).
In fact, Tintri is one of the only few storage vendors to support the Horizon View Composer API's for fast provisioning of VDI linked clones. Nevertheless, it's quite simple to install the VAAI. This will allow you to take VM level snapshots through the vSphere Web Client.

The snapshot is not offloaded to the array in any way. From what I can tell, the VAAI snapshot offload capability is a special command available only through the API, and it's leveraged by VMware View (VCAI) and by vCloud Director. This information comes from http://www.vmware.com/files/pdf/techpap ... ration.pdf. If anyone can find anything stating otherwise, I would love to know.
Until then, again, +1 for Veeam integration with Tintri snapshots.

"VMware vSphere® Storage APIs – Array Integration (VAAI), ... enable the ESXi host to offload certain storage operations to the array, which reduces resource overhead on the ESXi hosts and can significantly improve performance for storage-intensive operations such as storage cloning, zeroing, and so on....."
Tintri's documentation also show that the snapshot is offloaded to the array:
