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)
Regards
Dimitre
