Depends on the disk speed, the network speed, the backup medium, the actual mode of the backup (cold backup, RMAN backup, etc .....)
One one of our machines a OS level flashcopy cold backup of a 300 GB database takes about a minute, the same backup we did of basically the same database on a development system with a normal copy over the network did take 5 hours.
