22.3. Identifying Useful Directory Server Features for Disaster Recovery
- Backing up databases and verifying the backups regularly
- Multi-master replication, chaining, backing up databases, and monitoring the server with a named pipe script
22.3.1. Backing up Directory Data for Disaster Recovery
ldap://server.example.cominstance daily at 22:00 (10pm):

dsconf backup createcommand backs up the directory data without having to stop the server first.

22.3.2. Multi-Master Replication for High-availability
Example 22.1. 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.
