All the Oracle Internet Directory data you need to back up and restore is in the underlying Oracle Database. To learn how to back up and restore Oracle Database, see: Oracle Database Backup and Recovery User's Guide.
You can back up a small directory or a specific naming context by using ldifwrite.
To back up and restore your Oracle home and Oracle instance, see Oracle Fusion Middleware Administrator's Guide.
Note:
If you back up data from an earlier version of Oracle Internet Directory, such as 10g Release 2 (10.1.2.0.2), then restore it on a node running 10g (10.1.4.0.1) or later, you must update the password policy entries as described in "Password Policy and Fan-out Replication" on page 30-32.
