Hi Win200x Server Backup Techs,
I'd be interested in info on this too. I just went through this, forced
to move NT disks around. Our one big shared network disk on Win2003
Server filled up and first we split off to a 2nd disk, then moved to a
much larger single disk chunk again, all on an IBM SAN. I kept the disk
id E: the same on the same server name etc, but just couldn't stop
Tivoli from backing up the whole thing again and again. After doing our
normal 6 week incremental and an image backup in case etc, I created a
FLUSH domain with 2 day retention and smaller version settings etc,
moved the Win2003 server to that domain, and flushed out the older FULL
backups. I then moved it back to the domain it was in.
So what "flag" does the Win200n Tivoli client use to backup a file
again, besides update date or archive flag?
Thanks..

Hi Farren,
Been here before ourselves... might be interesting/useful to work out
why the TSM client believes the file has changed. Run a backup of the
files that you believe it should *not* be backing up but is, but with a
trace enabled (hmn, I forget the exact traceflag we used now - might be
worth you taking a look at Richard Sims' (not-so!)Quick Facts for the
correct one) and this will tell you which attribute it is that it thinks
has changed, be it NT permissions, modified date etc... I remember
uncovering a somewhat undocumented '-testflag SKIPNTSECURITYCHANGES'
during this saga last year which did exactly what the name suggests...
Hope that helps point you in the right direction...
Rgds,

Morning all TSMers
Running TSM 5.1.6.2 on a Solaris server. Attached to 1*3494 library with
two*3590H1A drives.
I have a possible problem here. One of the sys admins for the Windows
2000 servers has informed me that they are going to need to replace an
entire Windows 2000 server due to severe hardware issues that they have
been experiencing. No amount of support has fixed the problem and hence
the drastic move. The server has got some 820,000 files on it amounting
to approximately 450GB.
Here is what we want to do. Configure a new server and copy the data
across in such a way that it doesn't look like it's changed. The new
server will have the exact same Node name, file system layout etc. I
don't really want to be faced with backing up the entire server all over
again as we are getting low on both tape space in the library and
database space. This was not something I had foreseen.
>From what I have been told, early tests have not been promising and TSM
still thinks files have changed even if the last change date/time etc
has not altered. Does anyone have any experience with this or any advice
they can give that may help us avoid a long backup that will hog system
resources?
Many thanks in advance
