So, we all seem to agree that the Windows 2008 SystemState is very large (seems
to be about 6GB on a fresh 2008 R2 installation), but is there anything we can
do about it?
It looks like it does a FULL copy of everything in the SystemState every night.
I've never really paid attention to the SystemState backups, is that the way
it's always worked? A FULL every night? No TSM incremental-forever magic?
OK, so if we are saying "that's just how it's going to be" what are folks doing
about it? There seems to be a few possible issues:
- Bandwidth issues to clients with slow connections.
- The size in the storagepools of those larger SystemStates.
- The lengthening of the backup windows on all hosts because of the
time needed to check/backup the systemstate.
Changing the retention policy or dedupe can help with the large size
they will take on disk/tape, but I'm not sure what can be done about the other
2 issues?
We are rolling out a bunch of 2008 servers and as each host is
upgraded, the backup goes from 5 minutes to ~1 hour to backup. My TSM server is
going to get hammered: number of serviced connections are going to go way up as
connections linger longer, the amount of data sent from the TSM server to the
client to compare is now ~400MB, hitting the TSM DB pretty hard, overall TSM
server performance is going to suffer and I might have to buy more
horsepower/storage just to support the 2008 SystemState.
Options? Anyone? Anyone? Buhler?
Does TSM have some magic up it's sleeve in a future version that can help us?
(I just started testing the 6.1.2 version that just came out, but it behaves
the same with the systemstate).
About all I can think of is not backing up the systemstate or perhaps only
backing it up once a week, but neither of those are good options.
Anybody else concerned about this or am I just being "the boy who cried
ARMAGEDDON"?

I am not aware of any links off-hand to any official Microsoft statements.
Why would your customer doubt this? Alternatives that come to mind:
- Take a look at the install footprint of a base Windows 2003 vs. Windows
2008:
Windows 2003: C:\Windows has 16,000 files/3 GB
Windows 2008: C:\Windows has 71,000 files/15 GB
There are, of course, other files, but the size of C:\Windows alone is very
telling.
- If you do a google search on "windows 2008 system state size", you'll
probably find some credible, albeit anecdotal evidence of the size.
- If you run a TSM backup-archive client "backup systemstate" command,
you'll see the size.
- If you get the VSS SDK, it comes with the vshadow.exe tool that you can
use to get a sense of the size:
vshadow -p -wm2 > youroutputfile
Then review the output. Run the same command on Windows 2003 and compare
the sizes. There is clearly a lot more in the 2008 version.
- If your customer needs to hear it from Microsoft, then perhaps this is a
question to ask directly of Microsoft.
