Might work...  if only I had time to work on such a thing and test it
out...  Wouldn't the 1GB files be backed up everytime, since the
timestamp will have changed?

Well Paul  it looks like you need a low tech solution

I assume Vista has some sort of NTBACKUP equivalent?

Run your NTBACKUP of the systemstate as a precommand and put it through the
GNU split utility to give you files of say 1GB in size. do it as a script
and add a sleep at the end to give VSS time to quiesce before the TSM
backup starts.

Exclude systemstate from the TSM backup (or maybe put it in a class with
freq of 14) , but turn on subfile backup for the split backup files.

Voila - poor man's dedup.

Joanne,

Thanks very much for the detailed response.  We really need relief on
this.  We have a couple of thousand Windows systems, and they will
eventually be upgrading to Vista.  As they do so, they will uncover
this huge problem;  A problem for them, in that their backups will
run longer and they will be storing much more data than they need;
and also a problem for the TSM server administrators as they put an
increasingly huge load on the network and TSM server infrastructure.

This solution, as it is now, is virtually unworkable for us.  The
clock is ticking, and we need relieve ASAP.  Waiting for the next
major release is too long, IMHO.  It would have been nice if this
were addressed with the initial support for Vista in TSM, but that's
water over the dam now.

Thanks for listening.

..Paul
