Hello,

1) using VCB you take off the load from the ESX server (VCB proxy sends the 
data to TSM, ESX just creates the snapshot)
2) Using TMBR in each VM - question is why to do that. In virtualized 
environments you do not need to think about dissimilar HW so TSM based image 
backups can help you with DR (speaking of Windows world).
Running all VM backups concurrently can be very stressfull to the ESX host.

Subject: [ADSM-L] TSM+VCB against TSM+TBMR on each VM

Hello Everybody,
I am TSM Server admin, but I am a beginner in VMWare backup/restores.
I am trying to understand some basic things like VCB.
In my opinion, VCB backup/restores are a little bit complicated.
Would it be possible to give main advantages and disadvantages for two 
different ways of backup/restore for VMs:
1)     TSM + VCB based on "dsmc backup vm";
2)     TSM + TBMR on each VM with direct backups to TSM Server.
I do not need very detailed information - main ideas what is better and why.
Thank you very much in advance.
Kindest regards,


Grigori G. Solonovitch
