Chapter 14: Replication

This book excerpt is from Chapter 14 of The Backup Book by Dorian J. Cougias which discusses some of the technical challenges associated with replication.

Replication is the process of automatically duplicating and updating data on multiple computers across a network—usually to a geographically dispersed location to fail-safe the data from building loss. The simple description of replication is that it moves data from source computers to destination computers.

It gets a bit more complicated when you implement replication software, because at that point you have to know about three different variations dealing with the source of the data, how often that data is moved, and whether the data transfer is synchronous or asynchronous.

This chapter includes sections on the following topics:

  • Basic file replication
  • The source data for replication
  • Requires Free Membership to View
