Directory and system administrators should have a disaster recovery plan in place in the event of a natural, human-induced, or catastrophic disaster. If your directory service is distributed over multiple individual servers, back up all the servers individually or back up all the directory data from a central location.
Alternatively, consider replication as a backup and restore strategy. Replication provides faster restores and more update data from another replicated server. For more information, see Restoring Replicated Directory Servers.
$ backup --backUpAll --backupDirectory /tmp/backup
Make sure that the schema subdirectory is present within the install-dir/config directory.
All items are required when restoring the server.
