Backup Job Rate more than halved when backing up Hyper-V VM vs Physical Server
Hi,
We recently P2Ved one of our fileservers, prior to which we were able to backup with a job rate of 2GB+/min and a total backup runtime of around 15 hours.
Since P2Ving the server, we now only get a job rate of around 900MB/min and the total runtime is now around 32 hours.
Does anybody know why the job rate would have drop so significantly?
Environment Details:
We have gigabit ethernet between the VM host and iSCSI SAN (Dell Powervault MD3200i) and we backup to tape (a Dell PowerVault TL2000)
The VM is a Hyper-V VM running on a Hyper-V cluster but we are not using the Hyper-V agent for backing up, just the standard RAWS agent, OS is W2K8 R2 Standard
The server BE is installed on is physical with the tape library connect via SAS, BE version is 2010 R3 SP1, OS is W2K8 R2 Enterprise
Cheers
Adam.

Was the file server a media
Was the file server a media server when it was physical?

As part of testing for a case
As part of testing for a case I had open with Symantec, it was at one point a media server.

So before it was virtualised
So before it was virtualised it was being backed up by another media server, it did not backup itself to tape?
Is the iSCSI traffic between the file server nad the SAN separate from the normal network? or is it on the same network?

When you go from physical
When you go from physical resources, to virtual resources, more likely you lost "horsepower."
Either grant it more resources to do the backup, or backup the VHD file itself. Backing up the VDH is almost faster than a normal file level backup. The Hyper-V agent being preferred!
There is an online portal, save yourself the long hold times. Create ticket online, then call in with ticket # in hand :-) http://mysupport.symantec.com "We backup data to restore, we don't backup data just to back it up."
