You normally schedule replication processes with Fastback (or do them
manually), or you can engage the CDP technology to make it real-time.

I haven't been able to do a good field (i.e., long-distance fat tub of
data made up of zillions of little files) test yet, so I still need to
find out just how "real-time" it is. Bandwidth throttling is an option,
so large changes could be set to be "semi" synchronous.
