Hello Eric, 

If the windows folks are using DPM I suspect that they are using the Microsoft 
Hyper-V support and not vmware. I have not heard that TSM support Hyper-V 
client per say.

When DPM first came out they only supported backing up to disk. To move the 
disk backups to tape required another backup product like tsm to backup the DPM 
server. 

I know that Microsoft has added tape support to DPM, but the TSM tape support 
may still be better. 

You can always install a tsm client on each virtual machine, but I suspect that 
the windows folks would not like that.

Subject: [ADSM-L] Backing up running VM's

Hi TSM-ers!
Our windows department is looking at different backup products for
backing up their server.
They have two major problems with TSM. One I cannot solve: the TSM
client license is processor based, so quite expensive for the majority
of small servers. I think we all agree that the TSM client license
should be capacity based, but IBM aint listening here...
The other problem is that they state TSM cannot backup running VM's.
They now use a product called DPM to make snapshot copies of running
VM's.
I'm not really familiar with Window server management, especially when
it comes to virtualization, but I know one thing: TSM is one of the
leading, cutting edge backup products, so I doubt TSM is not supporting
this feature.
Does anybody know whether it is possible to make snapshot backups with
TSM of running VM's?
Thank you very much in advance for any reply!!!
Kind regards,
Eric van Loon
