VCB backup failed - The virtual machine identified by abc.com is unknown. Exit Code: 16

Hi,

Check in VirtualCenter the name of this virtual machine, and compare with name in saveset of client, should be the same, considering case sensitive.

Hi Luis,

Thanks for your suggestion. But looks like the problem still persist, any other idea or suggestion?

Thanks

Try mount VM via cmd on machine where is installed VCB

Example:

vcbMounter -h virtual_center_hostname -u user -p password -a name:VIRTUAL_MACHINE_NAME -t fullvm -r D:\\VCB\VIRTUAL_MACHINE_NAME -m nbd

Before verify if not exist snapshot created on this machine.

Regards.

The impact is just create the snapshot of virtual machine.

Check in virtual center, right click on VM > Snapshot > Snapshot Manager there must be exist snapshot with name something like this VCB Backup...if had exclude the snapshot and try the command to create again.

Regards.

I have ran the manual vcbmount command from vcb proxy, but seems like something wrong on the command, because I run on working client def.com still getting error.

Any idea?

abc.com >> problem client

def.com >> backup is fine.

Try to unmount F:\mnt and after mount again

Unmount:

vcbMounter -h VirtualCenterHost -u username -p Password -U F:\mnt

Mount:

vcbMounter -h VirtualCenterHost -u username -p Password -a name:abc.com -t fullvm -r F:\mnt -m nbd

Sorry, in my last post I wrote wrong command, in parameter "-r F:\mnt" try "F:\mnt\abc" don't "F:\mnt" the vcbmounter command create this directory

How the directory F:\mnt exists, he can't created and send error "Error: Mount point "F:\mnt" already exists."

vcbMounter -h VirtualCenterHost -u username -p Password -a name:abc.com -t fullvm -r F:\mnt\abc -m nbd

Hi guys,

Thanks for the assistance. I have found the root cause, the VM does not have VMware Tools installed. After installed the VMware tools into the VM, the backup is completed successfully.
