Chapter 1. Disaster recovery tools in IdM

A good disaster recovery strategy combines the following tools to recover from a disaster as soon as possible with minimal data loss:

Replication
Replication copies database contents between IdM servers. If an IdM server fails, you can replace the lost server by creating a new replica based on one of the remaining servers.
Virtual machine (VM) snapshots
A snapshot is a view of a VM’s operating system and applications on any or all available disks at a given point in time. After taking a VM snapshot, you can use it to return a VM and its IdM data to a previous state.
IdM backups
The ipa-backup utility allows you to take a backup of an IdM server’s configuration files and its data. You can later use a backup to restore an IdM server to a previous state.
