What is the difference between disk backup and data replication?
The terms have been used interchangeably quite a bit lately because of the popularity of disk backup that is really gaining. The thing is, disk backup is technically another form of media that your backup application or solution can write to. Data replication technically should be an exact replica (as the name implies) of your data.
That's an important distinction because now, if we're talking about disk backup, we're talking about faster backup than tape, but not faster restores than data replication. Data replication almost allows you to do almost instant recovery of your data -- a very specific distinction between the two.
