17.3. Identifying Useful Directory Server Features for Disaster Recovery
- Multi-master replication, chaining, backing up databases, and monitoring the server with a named pipe script.
- Backing up databases regularly
17.3.1. Multi-Master Replication for Disaster Recovery
Example 17.1. Scenarios for Multi-Master Replication
- For a single server failure, all of the data stored on that instance is both accessible and retrievable from other servers.
- For the loss of an entire office or colocation facility, servers can be mirrored at an entirely different physical location (which is aided by Directory Server's wide area replication performance). With minimal effort, traffic can be redirected to the replicated site without having to bring new servers online.
