Backup exec 2012 back up / deduplication speed

Created: 23 Sep 2013 | 4 comments


We are running BE2012 on Windows server 2008. The server has 32Gb Ram 2 4-core processors which should be more than enough. We are backing up virtual machines from hp 3par to eva4400 and the speeds that we are getting aren't satisfactory. When we run backup to a deduplication disk storage the maximum speed is about 4G/min and if we backup to a normal disk storage it's about 5G/min. As a comparison when we copy a file from the 3par to eva the speed is over 500M/s. I realize that the backup isn't suppose to be as fast as the copy but is the 5Gb/min really the best speed we can get? That's like 80Mb/s?

Assuming you are backing up these Virtual Machines from an ESX host what is the transport method in use? How did you test copying the files from 3par to eva? Was this done via Backup Exec Server? As when the Backup is performed the data would travel from 3par to Media Server and then to eva 4400 unless you are using SAN transport method.

We are backing up the esx virtual machines using SAN transport method. and the copy test was ran via the back exec server. What kind of speed should we be getting?

...sorry, but copying files between HP storage arrays on a fibre back-bone isn't a good indication of things.

It's also going to be dependant on the configuration of your EVA4400...disk type and size, vRAID level etc.

Ok. The eva has 28 400GB 10K disks running on vraid5. I'm really just looking for some idea how fast the backup should be or is this really the max speed we can achieve with this setup.
