AFAIK the only way you can do it with the TSM + VCB support, is to set
up multiple schedulers, each with its own list of fullvm's to do.
That's what I said I think any more than 20 servers is not really
manageable with the TSM+VCB support.
Support for scheduling stuff in parallel is one of the reasons to go to
another product, like the Storserver TSM client for VM....

Thanks Wanda,  This is good I appreciate your response.


Our VM environment is small (currently) but growing. We have two VCB
proxy servers backing up (7 VM's) on one and (11 VM's) on another.
Friday we do a full VM backups.  I am currently have the setup doing the
VM backups (FULL and INCREMENTAL) one after the other,  is there a way
that I can set/schedule  the VM specifically the FULL VM backups to run
Concurrently  all  (11) vm's  at the same time? This would really help
cut down on the amount of time the backups take.
