What is the best configuration for Virtual appliance mode

[JulienF]

hi All,
I’m trying veeam backup on virtual machine but my backup on NFS are slow (bottleneck: source).

Someone can tell me what is the best configuration for my infrastructure (virtual appliance mode) ?


Thanks,
Regards,
Julien

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?

[JulienF]

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.

[Gostev]

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.

[JulienF]

do you know an other way to backup VM with a best speed ?

[Gostev]

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

[JulienF]

thanks for your answer Gostev I will check how I configure Virtual appliance mode (hot add).
my NFS server is an ubuntu on DELL PE2950.

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?

[JulienF]

spindles ? What do you mean ? (sorry for my english )

The number of disk drives in your chassis.

[JulienF]

I have 12 disks of 2To (raid 5).

[Gostev]

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!

Thanks Gostev.
