Red Hat Enterprise Linux ES release 3 (Taroon Update 4) Oracle Database 10g Release 10.2.0.2.0 SE

Not a big size database: 30GB (~18GB used), backed up on a NFS mounted drive (all filesystems are ext3 type).

full backup without compress: backup sets size ~13GB, elapsed 37min full backup with compress: backup set size < 2GB, elapsed 26min

BACKUP OPTIMIZATION OFF
PARALLELISM 1 (SE doesn't support parallelism > 1)

Dimitre
