17.0 Backing Up and Restoring NetIQ eDirectory

NetIQ eDirectory is designed to provide fault tolerance for the tree through replication, so that if one server is not available, other servers can provide access. Replication is the primary method for protecting eDirectory.

Replication, however, is not possible in a single-server environment. Also, replication might not provide a complete restore of individual servers in case of a server hardware failure or other damage, or in the event of a disaster such as a fire or flood in which you lose multiple servers. Backing up eDirectory on each server increases the fault tolerance for your network.

The eDirectory Backup Tool enables you to back up the eDirectory database on your individual servers. It has the following benefits:

The eDirectory Backup Tool is designed to give you a complete backup and restore of the database and associated files on an individual server. It does not support backup and restore for individual objects or sections of the tree.

Also, it must be used in conjunction with file system backups to put the eDirectory backup files safely on tape.

For OES 2 Linux, you can back up eDirectory using NetIQ Storage Management Services. SMS provides a target service agent (TSA) for backing up and restoring eDirectory. TSANDS services provide an implementation of the SMS APIs for the Directory trees. Applications can make use of this feature for backing up and restoring eDirectory objects.

TSANDS supports the following features that backup applications can take advantage of:
