Hi,

Could someone help us determine what to expect with this situation :

- Backup server : SERVER_A
- DB server : SERVER_B (as StorageNode or MediaServer with 4 SAN Drives 
attached, see below)
- DB server : PA_RISC HP-UX 11.11 (HP 9000 rp7410)
- Oracle 10g R2 DB : 3,6TB
- Real amount of datas : 50GB
- RMan allocating 3 channels (SBT)
- RMan MAXSETSIZE 128G
- RMan MAXPIECESIZE 128G
- RMan FILESPERSET 32
- Drives : 3 emulated LTO3 (VTL Quantum PVX 2TB/H)

At the moment, the backup process lasts 4.5 hours (only 8 to 10GB/H throughput) 
!

Is it something normal, do you have any suggestions ?

Any comments appreciated

ThX for your advices ...
