Hi All

I have a database here that is nearly 1 TB..curently the hardwrae it runs on is 8gb Ram and 2 Cpu 1000Mhz Hp-Ux machine..it takes almost 15hours for the backup.we are running oracle7.3.4 but plan to migrate it to oracle 9.2..I am more worried about the backup time..Is anybody running a terrabyte database OLTP type..wherein we need to take a RMAN backup preferrably and what sort of backup startegy you have employed incremental ,cummulative ? for a TerraByte Database ?How much time does it take to backup and your hardwrae specs ..would be helpful when we tender a new hardware.
