Hi,
The main different between CBMR and TBMR are following.
CBMR:
* Can work stand-alone and leave it's own life without TSM.
* CBMR can save the server configuration layout together with the backup or
outside the backup such USB/FDD or Network Share.
* CBMR will backup minimal of data (OS, System State, TSM and Profiles) or
more, You can add more data manually to the CBMR backup.
* When CBMR use TSM as a repository it will collocate all data one large file.
That mean you will get less tape mounts during recovery
* The bad thing I can see, is if you do a CBMR backup, let's say 1000 servers
and the OS backup will be 20GB each and the on top of that do a TSM backup of
the same data of all 1000 servers, you will end up with a lot of extra space in
your TSM environment.
And IF you are moving over to TB Lic model you can end up to pay double amount
of money for CBMR lic to IBM.
* As Daniel Sparrman say, CBMR works stand-alone. But I know that Cristie
Software working hard on a Centralized GUI to overview CBMR/TBMR. And their are
a GA version that you can request at their website.
* You can schedule CBMR from the TSM Server and get CBMR reporting back to TSM
if it works.
TBMR:
* The main goal with TBMR when it was requested by a end-user and before it was
released was just to solve the space issue that CBMR was created. TBMR will
only create a small about of configuration peach locally on the HDD and let TSM
back it up.
* With TBMR you can end up that a recovery takes forever if you don't use
Collocation on our slow storage pools.
* The good part is that you can then easy put a SLA on each server and then
only use fast storage pools for SLA1 server and slow and cheap media for
non-important servers.
* TBMR can only create data locally on the server so the TSM BA Client can
backup the information. That mean non of the TBMR information/data can be saved
outside TSM Server knowledge, (because TBMR don't do any backup)
* TBMR has the TSM BA Client on the CD, that mean before you upgrade the TSM BA
Client and you are using TBMR, contact the Cristie UK support and see if the
latest TBMR recovery CD has support for the BA Client you want to use.
* TBMR works with Client-Side Dedup
COMMENT:
* Both software are using WinPE1 and WinPE2 for Recovery of Windows Servers.
* Both has Dissimilar Hardware Support
* Both works with Server Side Dedup. (I haven't test or heard if CBMR works
with Client Side Dedup yet).
I hope this helps as information for you all.
I preferred to use TBMR because I can easy overview it from the TSM Server much
easier and it takes less space on all storage pools.

Well, when I used it, the only data stored on the CBMR server was operating
system data, not user data. Unless that changed, the big amount of data is
still used from the TSM server.
Like I said, been a while since I used it, but then, OS data was gathered from
the CBMR server and user data (that is, the large amount of data you will be
restoring which is databases, user files or whatever server you are restoring)
was restored from TSM.
Again, Christian Svensson knows this alot better than I do, I evaluated it once
and decided to go for TBMR for my customers out of simplicity.

I was using CBMR for quite long time and we are using TBMR now for quite big
number of servers (upgraded from CBMR).
CBMR can keep configuration on diskette, USB drive, network drive or on TSM
Server, but it does not meen it keeps backup data on TSM Server.
TBMR keeps configuration and backup data on TSM Server and can read them from
TSM after booting from CD by using WinPE1 or WinPE2 (depend on OS).
So only TBMR is totally integrared with TSM and cann't keep backup data on
disks or tapes.
We are using TBMR 6.3.1 and TSM Clients 6.1.3.3 and 6.2.2.0 with TSM Server
5.5.4.1. Everything is working perfectly.

I dont work at or use CBMR myself, but I did evaluate it once.
It does actually integrate with TSM since it uses TSM as a repository. So that
it would be a standalone product is wrong (unless something changed in a newer
version).
I'd still select TBMR out of several reasons though; a) same producer, easier
support b) It's using MS standards (as in ASR) c) It's easier to handle as to
licenses since again, it's the same producer b) It does what it's intended todo.
I have also heared from several customers that they were having issues related
to network cards when it came to CBMR, I guess I'll be corrected on this one by
Christian.

Of course, TBMR (TIVOLI Bare Machine Recovery - integrated with TSM Server)
CBMR (Cristie Bare Machine Recovery) is a backup system like TSM (to disks, USB
disks, tapes). It is not integrated with TSM directly.
