Hello everyone,
Has anyone come across a tremedously slow vmware backup when a VM has 2+TB vmdks attached? I am having this issue with two VMs. The backups are going through the SAN in a NetBackup 7230 3.0 version. Another info, sometimes the backups end with status 50 (client process aborted)
Any comments is very much appreciated.
Kind Regards,
David
slow backup could be because of many reasons, and its hard to find it for vmware backups.
if it is possible, first thing i would suggest you to check backup speed and time with NBD transport for testing, it would help to narrow down if there is any perfromance issues in SAN side.
I am also interested to know the VMware enviornment versions., does it enabled with CBT?
Hello RamNagalla,
I see your point. What really catches my eyes is that this is happening with just this two VMs. And they all have some vmdks with the size of 2 TB or more. But I will see if I can test it using NBD transport mode. I believe I have already tried that but I will double check it.
Hello Dtrostli1,
when you say same VMDK, are they really same VMDK shared with Two VMs? or same type of VMDKs with independent to each VM?
Suggest checking the VMKERNEL interface speed that can often be a cause of slow VM backups.
