Slow backup

[jbeunel]

Hi,

I have a replication job and the speed is very slow
The maximum speed is 20MB/s.

Both server are dell R710 ,64GB of Ram ,Bi XEON i7 3Ghz quad core HT TURBO with 6HDDX450GB 15K in raid 5.
I tested the disk speed i have about 600MB/s and i tested a ftp transfert between both server i have 60-70MB/s on a cisco 3750G 1gbit LAN.
When a launch a full backup or replication i have only 15-20MB/s.
The size of this VM is 55GB and take 46min to transfert with veeam backup.
If i do the same thing with vmware converter it take 6-8minutes max
Where can be the problem?
How can i solve this please?

Regards

What job processing mode are you using? Did you try to run VMware Converter from Veeam Backup computer? It would be best to let our support take a look at this in live over webex, as it is hard to guess the issue remotely.

I have a Dell R710 as a replication server and get very poor speed, i think it is something in the dell server why my backups are 10-15 MB/s ,i have not had time to investigate yet but ill post back when i get a chance,.

I use the replication with network option in veam using vsphere api.
I'll call the support tomorow.
I have the same problem on a Dell R610 et Dell 2950 ,same speed.
i use vsphere essential 4.
I let you know what i can found with the support.

We have to put the all last vsphere update and it should work arroud 45MB/s.
I'll try that soon.
If it work for you let me know.

Im My case the ESX server is just my replication server and first backup is around 30-40 but then all subsequent are slow around 10-15mb/s its not really an issue for me as its not the main 3 node production cluster.. but ill have a play with firmware and things and see if i can get better speeds and will drop you a note for sure.
