Backup a VM with 120Mb/min rate for a Gigabytes connection? too slow!!

[OBF]

Hi team,

We have a Symantec licences as the following:

SYMC BACKUP EXEC 2014 SERVER WIN PER SERVER BNDL STD LIC EXPRESS BAND S BASIC 
SYMC BACKUP EXEC 2014 AGENT FOR VMWARE AND HYPER-V WIN PER HOST SERVER BNDL STD LIC EXPRESS BAND S BASIC 
SYMC BACKUP EXEC 2014 AGENT FOR APPLICATIONS AND DATABASES WIN PER SERVER BNDL STD LIC EXPRESS BAND S BASIC 

We want to backup virtual machines data on: 

• NAS px6-300d 18To
• DELL autoloader PV TL1000 drive with LTO6 drives 

The virtual machines are connected with Giga bytes ports, backup server also and the switch is a Gigabytes HP switch.

The problem is that the transfer rate of any VM (to NAS or to TL1000) is always 120Mb/min max!!!

Editing the bloc, buffer size and compression didn't increase this rate.

This is too slow and we should have at least 800Mb/s approximatively.

I generate a ticket yesterday (case number 08089461) but still not have any reply!!!

Can you please advise ASAP?

Thanks in advance.

Regards,

Farouk

Hi,

If you turn on jumbo frames, does it have any impact?

Those Iomega NAS units do have an antivirus installed, so make sure that if this is the case, that it is not scanning the VMs, or turn it off to test throughput.

Make sure that all your network ports are hard-coded to 1GB FULL. You can also copy a large amount of data from the NAS to the media server (and vice versa) to rule out network issues.

Lastly, if you have an AV installed on the media server, check to see if it isn't actively scanning the BE services, and if so, put in exclusions to prevent this.

Thanks!
