红帽全球峰会第 1 章 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-backuputility 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.
