Thanks for the info.
At least that is a bit of progress...

Subject: Re: Backing up SYSTEMOBJECT on Win2K machines


With Windows 2003 it will backup the entire system32 folder during the
system state backup of any file in it changes.  However, if no files
change under system32 then it will not back it up.  So it is somewhat
incremental but not a true incremental where only the files that changed
are backed up.

It's my understanding that all of the SYSTEMOBJECT files are backed up
with every backup(incremental).

>> Yes, that is true. Until you get to Win2003, then I believe
it is supposed to be a true incremental of those files, but I haven't
verified that.

Is it more efficient/better to have ntbackup backup the SYSTEMOBJECT to
a file before the TSM backup, then have TSM backup this file nightly
with the regular TSM backup?

>> Many people do that. It means only 1 file gets backed up by
TSM, therefore the impact on your DB is less.

Is there any problem with recovery of the machine using this
method(ntbackup then TSM)?

>>No.

Is there any advantages/disadvantages to using this method?

Advantages:
Less impact on your TSM DB
I have never run into this, but if your restore fails, you only
have Microsoft to deal with, no finger pointing since only Microsoft
tolls are involved.
Disadvantages:
How are you going to verify that it is working? You have
to visit each machine and set up a scheduled task to do the ntbackup.
If the ntbackup piece fails, TSM isn't going to be able to tell you.
Also, you have to train OTHER people in your shop on how to do
the 2-step restore if you aren't around; restore the flat file
from TSM, then do the ntrestore

Generally how many files does the SYSTEMOBJECT backup contain?
>> Depending on the machine, 1800-2000

FWIW:
>>Here's what I would suggest as the easiest solution. You are
keeping your client backups for 90 days, but I persionally would never
want to restore a Windows registry that is 90 days old!

>>You can assign the SYSTEMOBJECT to a different management
class than the other files. (Look in the TSM for Windows client manual
for INCLUDE SYSTEMOBJECT ALL). So create a management class that only
keeps 14, or even 30 days worth of your SYSTEMOBJECT backups, while
retaining other stuff for 90 days. That requires changes nowhere but in
the TSM Server, and greatly limits the growth of the SYSTEMOBJECT files
in your TSM DB.
