Mark, thanks for the suggestion about the system state.

But my question was more for the "roaming profiles" that are stored on about
10 w2k servers for all our final users. These profiles are made of numerous
small files (recent, cookies, desktop, favorites...)

>We use tsm server 5.1.5.4 and w2k clients 5.1.5.9. Probably due to the
very small size of profile files (most of the files are 1 KB big), the
restore session is very very long ... I suppose LTO technology is not so
well adapted to the read of such small files with mixed deleted blocks
on the tape!

We plan to define a special disk storage pool with NO migration and
maxsize of 2K, to keep all these small profile files on disk.<


If I may suggest something a little different...

1. Exclude the SYSTEMOBJECTS domain
2. Run a PRESCHEDCMD that uses NTBACKUP to backup the system state to a
flat file.
3. Back up the client.

Now, instead of 250MB of little files, you've got one big 250MB file to
backup (and restore). This process has three benefits: it greatly
reduces the number of database objects for W2K clients, the restore is
much faster, and this process is much more forgiving when performing BMR
to different hardware.
