Yes it is, but if you quiesce or stop the VM using that VMFS, you can back it 
up as a normal file from the ESX server using the
5.2.4 Linux TSM client. There are several papers on the TSM site about backing 
up Vmware ESX server and links from that over to
Vmware's site.


We do this weekly for our ESX servers...quiesce the VM's one at a time and 
backup the VMDK files. We have successfully recovered
these VM's at our disaster recovery site.

Hi,

VMFS and especially VMFS3 is special file system with implemented only
some functions of   classic FS, so probably backup using tivoli will
never work, or never work correctly.

Try vmware tools (integrated backup or something like) for tivoli, maybe this 
help.
