This is part of the new ESX 3 server. There are different processes for backing
up ESX 2.x servers. If you go to the TSM support
page and search on VMWARE you will find this one in particular which has a lot
of links to resources on both IBM and Vmware sites.
http://www-1.ibm.com/support/docview.wss?rs=663&context=SSGSG7&q1=vmware&uid=swg21175860&loc=en_US&cs=utf-8&lang=en
Then there's this Tivoli Field Guide - Using IBM Tivoli Storage Manager for
Backup and Restore on the VMware ESX Console
http://www-1.ibm.com/support/docview.wss?rs=663&context=SSGSG7&q1=vmware&uid=swg27005205&loc=en_US&cs=utf-8&lang=en
These processes use the Vmware API and some scripting on the ESX console to
either shutdown, pause or put the VM in a redo log mode.
Then you can backup the physical disk file(s) that make up that VM. This will
provide a consistant image, but depending on what's
going on in the VM itself it may not be a viable backup for application
recovery. As was pointed out in an earlier post, if the VM
is a SQLServer with open databases at the time, the recovery of the SQL
database(s) from the vmdk backup may not be useful. You
still need to run TSM (and agents) within the VM to get the file-level
granularity. We do a weekly backup of the vmdk files for each
VM as well as daily incremental backups withing the VM. Our recovery for a VM
is to restore the vmdk file(s) that make up the VM,
rebuild the definition if that is wiped also. At this point you should have a
bootable VM. Then from withing the restored VM, run a
TSM file-level restore with IFNEWER. It's not going to handle any deleted files
since the vmdk full backup was done. We have
successfully done this for recoveries at our site as well as at D/R.
We are just now getting a new ESX 3.0 server installed and I'm looking forward
to experimenting with the new "features" Vmware
incorporated in this version.
There is also a very detailed Perl script VMBK.PL that can do several different
methods of backing up ESX 2.x servers. It can be
found here http://www.vmts.net/vmbk.htm. It is a freeware (I believe) tool. I
have not tried it myself. It does not interface with
TSM, but it does work with Legato. So changes to use TSM shouldn't be very
difficult. How much work you would put into something
like this, or even the above procedures would depend on how long you will be
supporting ESX2.x servers before moving to the 3.0
release.

Just as clarification on this, I know it's available for Virtual Infrastructure
3, but I don't think you can use it with ESX 2.x.
Or have I already been proven wrong on that?

All VMware Users:
Using the VMware Consolidated backup you can do file level backups of windows
machines and system backups of other clients. There
is documentation on the VMware website about how to do this.
http://pubs.vmware.com/vi3/wwhelp/wwhimpl/js/html/wwhelp.htm
There is also a zip file that contains all the scripts that will be required.
All of this is from VMware. Email me if you want the
zip file.
Enjoy!
