Unless Tivoli writes their own code to perform the VCB snapshot, I
don't see this happening.  The way I understand it, the backup vm
command is calling the vmware vcbmounter etc... commands under the
covers.  What you are seeing is an integration and automation of those
tools.  We used to have to script this, and call the vm commands
manually, now at least TSM has integrated them into a single command.

I hope that they catch up a bit to what Netbackup is doing though.
They have a bit better integration with VMware servers, and allow the
application to backup "all" vms on a server rather than having to hard
code them.

While backing up straight to TSM is nice, it is also nice to have a
copy sitting on the VM proxy server ready to be restored.  Just one
less step to getting a server back up and running.

Just my 2 cents.

I am testing the backup vm function available in the
tsm 6 client. The full backup option uses a staging
directory on the server. The backup is placed there
and then the regular tsm backup sends it to the
storage pools.

Can the backup vm processs send it to the storage
pools directly without sending it to the staging folder.
The data is sent twice. Wouldnt it be better to
send it once.
