Hi Julien, sounds like you just need to get a faster storage. There is nothing you can do if your source storage is slow... what full backup performance are you seeing?

Hi Gostev,

thanks for your answer.
for FULL backup the speed is 30Mb/s.

Actually my ESX are backuped with ghettoVCB on the same NFS with 70Mb/s speed.

OK, trust me 30MB/s is perfectly expected speed and "normal" speed for hot add processing and NFS storage on 1Gb LAN - this is what just about everyone else has been reporting to my memory all past years. There are some tweaks available in v6 that may help increasing the speed, however for that you really need to have a very decent hardware backing that NFS storage (what is it, by the way) - or backup activities will start affecting your production VMs significantly.

Virtual appliance mode (hot add) is certainly the absolute best choice for the NFS storage.

There is no configuration, what I am talking about is a secret registry hack ;)
How many spindles do you have for storage on that DELL box?

That is pretty decent, I guess. I will try to dig up the key, and will PM it to you for the testing tomorrow. Please remind me if I forget!
