Many Thanks Wanda
I found a doc on the Developerworks site that suggests TDPs be used for
Oracle, Domino, DB2 and SAP, and some cases of SQL There is a teaser in
there that snapshots are "not yet supported", so I suppose that is an
inducation some sort of TDP/Vmware snapshot integration is in the works.
As to the other, I have a collegue here whose opinion I respect who says
the monthly thing is not do-able with VE, and as I have no test
environment I suppose I'll have to take that line in my design.
You might like to vote on the RFE he has created to address the issue.

I'm glad you've brought it up, 'cause it's a good question, I know there are others
(including me) who are going to run into the "get a monthly copy" requirement.
I'm thinking it's POSSIBLE it will work, and here's why:
The doc says you have to create a management class for control information and
make sure that stays on disk, even if your VE backup pool normally gets
migrated out to tape. Before an incremental/CBT backup runs, TSM does a
restore that looks like this in the activity log:
03/31/2013 20:01:13 ANR0504I Session 37241 for node NNNNNNNN(Userid=),
restored or retrieved Backup object: node NNNNNNNN
filespace \VMFULL-SASW03, object
\SASW03\SNAPSHOT_000003000_20130328201241\Hard Disk
1\JOB000003001\MBLK03ee.CTL, version 1 of 1.
(SESSION:
37241)
If TSM is retrieving the snapshot info that is stored, is that perhaps the way
it is making the comparison for CBT?
If that's how it works, then perhaps it could indeed maintain 2 separate tracks, if
backed up to 2 different "datacenter" nodes.
But I don't really know, I'm just providing this info in hopes of getting
somebody else to chime in with info.
Maybe somebody going to Edge could try and find out for sure?
As for your second question about Oracle, I do know that the way the new VE
"application aware" backups work for MSSQL is by invoking Microsoft VSS to
flush the buffers before the VE backup. That isn't going to happen with any
non-Microsoft application.
However you back up Oracle now, you should be able to continue doing. The VE
backup is run on a normal TSM schedule; I don't see any reason you can't do a
presched/postsched arrangement to put Oracle in backup mode. But either for
Oracle or SQL, the TDP is the only thing that is going to give you log
management along with the backups.

Subject: [ADSM-L] TSM for VE questions
HI All
Bear with me please, I'm just getting my head around TSM for VE and changed
block tracking.
I have a government customer that is subject to the Audit Act and so is very
sensitive about long term data retention. They are also very keen on
virtualized Intel environments and have a large number of Windows and Linux
boxes virtualized. They basically don't want any new physical hardware in this
space.
Currently on VSphere 4 we have TSM clients installed on all the VMs.
Now moving to VSphere 5.1 we want to use TSM for VE 6.4, changed block tracking
and Flashcopy for VMware.
First question. There is a point-in-time monthly-for-seven-years requirement. In the conventional
TSM environment we run a daily incremental and once a month an incremental to a "monthly"
node using -asnode. Is it possible to do something similar with VE? Still maintaining an
"incremental" philosophy?
Second. The customer is standardizing on Oracle under Linux or SQL under
Windows. SQL we can handle with VE, but I can't see anything in any of the
docs about Oracle. Do we have to install a conventional TSM client and the
Oracle TDP? I know that Oracle can use Flashcopy for Hardware, but can it
similarly invoke Flashcopy for VMware?
As always.pointers to the right parts of the manual are appreciated if I've
missed something.
