Issue about Netbackup and WIN SVR 2000 VM

Hello,

I am wondering about backup issue.

One of my clients use VERITAS Netbackup and VMware system.

1 weeks ago, One of VMs (especially windows svr 2000) had an issue.

When Backup process was run, CPU was increased up to 95~100% on Windows svr 2000 VM.

However, Other VMs were okay at the same time. Windows Svr 2000 VM only had a problem.

Are there any case or solution that is related to my issue ?

Thanks

So if there is no CPU usage inside VM you need to check what's going on with esxtop and CPU screen for affected VM.

If this happens each time you take a snapshot and can be reproduced that could be a bug with VMware Tools\ESXi.

Anyway first of all you need to check esxtop outputs when the problem appears again and some logs: vmkernel.log and vmware.log

Hi

Its pretty much out of support products and support.

In order to isolate the issue you would need to check the Guest utilization during the backup. Most probably the backup agent running inside the guest would be causing the latency or the guest wouldn't be getting the enough compute resources. MIgrate the VM to different compute group and initiate a perfmon, reiniatiate the backup to see where the problem relies

Thanks

-----------------------------

Net Backup Version : 7.5

VM Version : 7

VM CPU : 4 vCPU

VM RAM : 4096 MB

Guest OS : Windows Server 2000

ESXi Version : 6.0 3620759

vCenter Version : 6.0 3634794

-----------------------------

I'm a field engineer so It's hard to check and test all of things.

I'll request what you recommended for test to client.

CPU Process is increased up to 95~100% while Backup process run.

Win2000 VM looks high cpu usage in the vCenter.

However, If I connect the VM by using console, CPU usage looks normal in the VM.

Backup isn't run everyday, so I couldn't check the Process.

I should have checked process but I forgot when issue was happened.

If its a scheduled backup, you can also schedule the procmon to check what process is using what % during the backup process

Thanks

Thanks to give an advice.

I also posted question on Netbackup Community

Some users said that 'Netbackup no longer support Window Server 2000. so It might be a some compatible issue'

I think it may be right

If this problem will be happened again, I'll check it again what you gave me an advice.

I really appreciate to help me.

Generally speaking, this means that you can't install Netbackup agent on Windows Server 2000 and backup\restore it using netbackup agent.

If you backup a VM with Windows 2000 as a guest os, this doesn't matter.
