Hello,

I'm backing up Veeam Files with Symantec Backup Exec 2010 from a Repository VM that has LUNs attached as vRDM in vSphere Environment.

Nothing has been changed in my environment, and all of the sudden the backup rate went down from approximately 3GB/m to 560MB/m. This is really annoying.

Repository SAN Storage: IBM DS3512

LUN: Raid-5 7200 rpm x 11 disks.

Backup Exec: 2010 13.0 Rev 2896(64bit)

Virtual Machine: Windows 2008 R2 SP1 Enterprise

vCPU: 8 x 2.80 GHz

vRAM: 12 GB

vSphere ESXi 5.0.0,623860

LUNs are vRDM and the Mappings on different LUN.

Any help tips/ how to will be highly appreciated.

Thanks,

Backup Exec 2010 Performance Very Slow - Comment:03 Feb 2013 : Link

Hi once again,

Now I'm backing up different folder within the same VM but Veeam Files on different LUN and this LUN mapped through iSCSI Initiator.

Backup Speed:

State    Name    Device Name    Job Type    Current Operation    Job Status    Priority    Percent Complete    Start Time    Elapsed Time    Byte Count    Job Rate
Active    Critical VMs-1    IBM 3    Backup    Backup    Running    Medium    N/A    2/3/2013 11:41:22 AM    0:05:50    8,749,642,811    2,812.00 MB/min

Hello,

to my surprise, these LUNs has been mapped to the VM since I have implemented Veeam Backup as a vRDM and configured with Round Robin. After I changed the LUN from Round Robin to MRU, the backup speed back to normal;

State    Name    Device Name    Job Type    Current Operation    Job Status    Priority    Percent Complete    Start Time    Elapsed Time    Byte Count    Job Rate
Active    Critical VMs-4    IBM 3    Backup    Backup    Running    Medium    N/A    2/3/2013 12:27:27 PM    0:11:03    50,311,263,062    5,301.00 MB/min

Will keep monitoring the situation.

Thanks,
