>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.
