TSM client Installation On ESX Server

Hello,

I'm Installing TSM client on ESX servers. But client wants to backup each virtual machine seperately (need to install tsm client on each virtual machine). Is there a way other than this. I mean, can we install TSM client on ESX servers and from there can we backup Virtual Machines with out installing TSM client on each Virtual Machine.

Could you please help me as I'm new to VMWare infra.

Many thanks in advance.

Thanks & Best Regards,
