Directory Server Data Storage - Netscape DIRECTORY SERVER 6.1 - DEPLOYMENT Deployment Manual

Introduction to Directory Server
You can build on the default directory tree to add any data relevant to your
directory installation. An example of a directory tree for example.com Corporation
follows:
For more information about directory trees, refer to Chapter 4, "Designing the
Directory Tree."

Directory Server Data Storage

Your directory data is stored in an LDBM database. The LDBM database is
implemented as a plug-in that is automatically installed with the directory and is
enabled by default.
The database is the basic unit of storage, performance, replication, and indexing.
You can do operations like importing, exporting, backing up, restoring, and
indexing on the database.
By default, Directory Server uses a single database to contain the directory tree.
This database can manage millions of entries. The default database supports
advanced methods of backing up and restoring your data, so that your data is not
at risk.
You can choose to use multiple databases to support your Directory Server. You
can distribute your data across the databases, allowing the server to hold more
data than can be stored in a single database.
The following sections describe how a directory database stores data.
