What speed of backup has been seen within EBU?
Executive Summary: Best performance: 78.49GB/h (4.2 DMO-processless module). Hardware: 8 DLT 4000 tape drives each with its own SCSI controller 4 SUN2.9G disks in 3 DSCSI controllers. 1 disk on 1 controller 1 disk on 1 controller 2 disk on 1 controller 1 SSA with 30 1 Gb disks 4 metadisks of 3 Gb comprised of 3 concatenated 1 Gb disks Software: EBU 2.0.12.4+ Oracle 7.3.2.1 Legato 4.2 DMO-processless from Legato (beta code) Database: Block size: 16384 Tablespaces: 1 Capacity: 21.6 GB Notes: A) The backup results above is extrapolated form a 21.6GB database. Assumption here is that there are enough clones of tested disk configurations to get this extrapolated number. B) The difference should be little between 2.0.12.4 and 2.0.12.4+. For Legato, the key to having a faster backup is to use the DMO-processless from Legato, which is not generally available. Without it the performance drops to 45 Gb/h.
