For those who haven't learned (yet), MS in Win2K (and TSM in 5.1) have taken
steps to address this; Win2K allows restore directly to existing C-drive,
whereby the backup product brings down system objects in a way that gets
them restored at the next reboot(except for the hardware specific pieces).
This can be (and has been) scripted (by at least a few customers), in such a
way that server recovery is possible -- the only limitation is TSM can only
handle non-authoritative restore of Active Directory (and other "shared"
registry/system objects).
Solaris has jump-start, HP has Ignition, AIX has mksysb -- they all have
their limitations, but that just makes our life abit more interesting.
One customer I helped deploy the old ADSM-pipe program to create a
mksysb-like package for the Solaris' equivalent of rootvg (and he liked it
alot!) Another customer engaged Sun professional services to script
together the config's for their E10K nodes and E450's (about 40 machines) so
they could periodically update a "standard image" jump-start CD (for each of
the two machine types),,, last I heard, they were happy with that solution
for their DR "server recovery" needs.
At SHARE, IBM/Tivoli acknowledged they were working on a BMR solution for
Win2K; no commitment to ever delivering said solution, but (at least)
they're looking at it. Win2K is (essentially) the only platform that
doesn't contemplate bare-metal restore in a mksysb-like fashion.
For my customers, I still advise them to use NTbackup.exe for the System
State backups (to a file that gets picked up by c$ incremental) -- in order
to allow point-in-time, authoritative restore of system objects. We
developed that approach (and discussed it, on this list) almost two years
ago -- we certified it for point-in-time recovery of AD, DC's and Exchange
Server in December, 2000.
This stuff is a royal pain, but not exactly rocket-science... just takes
proper funding and decisive commitment by platform-specific customer
personnel.

The issue is actually more complex for IBM/Tivoli. They typically do not
implement solutions that have potential integrity issues and they are
targeted toward enterprise recoveries in case of a disaster.
Unfortunately, none of the Disaster Recovery providers recommend BMR because
of HAL issues in the windows world and it being much easier to guarantee a
successful recovery for UNIX systems by restoring to an alternate drive and
booting. What the DR providers do like is the mksysb of AIX. That is a
great tool.
Tivoli does recognize the fact that customers must have a bare metal
recovery to identical hardware for windows. I do not know when, but they
will eventually have a solution for this. I believe this is the convenience
case.
If you are a business partner, you should be making the business lost case
to Tivoli because of the missing BMR capability. I encourage all business
partners to make that plea with supporting documentation to Tivoli.

There is a problem: all other software, like Brightstor and Netbackup
support this function. Since the windows users are getting more, we cannot
ignore the requests from them. I lose about 4 case which Brightstor and
Netbackup take these case because of the lack of this function. TSM is a
very good solution, but is still not a complet solution. People do not think
about the disaster and disaster recovery, they just think of convinient,
especially they spend lots of money to build a solution.

IBM is the only company that provides this capability for its operating
systems. Standalone restore on the mainframe, mksysb on AIX. These are
included free with the OS. This is a OS vendor issue. They simply do not
recognize the benefits of the capability and are not focused on SAR because
they do not see it as a problem.
The place that Tivoli needs to step in is make things like mksysb integrated
as a special backup capability that and manage the associated media and
provide a boot strap wrapper to invoke the native system's capability if the
are ever created.

Subject: BareMetalRestore
There has been a lot of discussion on bare metal restore with TSM and other
products. It seems we're all held hostage to purchase expensive products
that have this capability. Unfortunately in times like this we've all had
our budgets cut, at least I have, and would like our software vendors,
IBM/TIVOLI in this case, to make their products more robust. After all we do
send them maintenance money for software updates and expect the product to
get better.
I'm just wondering how serious IBM is about getting TSM to "WORK" with the
various OS software vendors, i.e. Microsoft, HP, Compaq, Sun and the like,
to find out what it takes to get it's product to do bare metal restores. If
TKG could make it work why can't IBM? Or don't these guys talk to each
other?
My little rant for the day!!!!!
