Hi Matthias,

you should get more!
We backup SAP R/3 4.6C directly to tape and get the following statistics.
Our TSM Servers is an AIX box (H50) with 1GB memory. Our network is
ATM 155Mb and we use 3590E11 drives in a 3494 ATL.

BKI0011I: Number of bytes left to be saved: 0 Bytes (0.0%) of 52.053 GB.
BKI0022I: Average transmission rate was 71.469 GB/h (20.329 MB/sec).
BKI2019I: Compression ratio for backup was 1.70.                    
BKI0021I: Elapsed time: 46 min 55 sec.                              

We use 2 sessions (as we have 2 tape drives) and read 3 files per session
in parallel. And we use runlevel compression to remove the binary zeroes of
the unused space.

Our .UTL file looks like:

MAX_SESSIONS 2
MAX_BACK_SESSIONS 2
RL_COMPRESSIONS YES
MULTIPLEXING 3

SERVER xy SESSIONS 2

Hope this helps

Kind regards
