the parameters of the task and initiates the task. As soon as the task is complete, the task entry is

removed from the directory.

The cn=backup entry is a container entry for backup task operations. The cn=backup entry itself has

no attributes, but each of the task entries within this entry, such as cn=task_ID, cn=backup,

cn=tasks, cn=config, uses the following attributes to define the backup task.

A backup task entry under cn=backup must contain the location of the directory to which to copy the

archive copy (in the nsArchiveDir attribute) and the type of database being backed up (in the

nsDatabaseT ypes attribute). Additionally, it must contain a unique cn to identify the task. For example:

dn: cn=exam ple backup, cn=backup, cn=tasks, cn=config

objectclass: extensibleObject

cn: example backup

nsArchiveDir: /export/backups/

nsDatabaseType: ldbm database

As the backup operation runs, the task entry will contain all of the server-generated task attributes listed

in Section 2.3.15.1, “Task Invocation Attributes for Entries under cn=tasks”.

nsArchiveDir

This attribute gives the location of the directory to which to write the backup.

The backup directory here should usually be the same as the one configured in the nsslapd-bakdir

attribute.

If this attribute is not included with the cn=backup task, the task will fail with an LDAP object class

violation error (65).

2.3.15.5. cn=restore

A database can be restored through the command line by creating a special task entry which defines the

parameters of the task and initiates the task. As soon as the task is complete, the task entry is removed

from the directory.

The cn=restore entry is a container entry for task operations to restore a database. The

cn=restore entry itself has no attributes, but each of the task entries within this entry, such as

cn=task_ID, cn=restore, cn=tasks, cn=config, uses the following attributes to define the restore

task.

A restore task entry under cn=restore must contain the location of the directory from which to retrieve

the archive copy (in the nsArchiveDir attribute) and the type of database being restored (in the

nsDatabaseT ypes attribute). Additionally, it must contain a unique cn to identify the task. For example:

dn: cn=exam ple restore, cn=restore, cn=tasks, cn=config

objectclass: extensibleObject

cn: example restore

nsArchiveDir: /export/backups/

nsDatabaseType: ldbm database

As the restore operation runs, the task entry will contain all of the server-generated task attributes listed

in Section 2.3.15.1, “Task Invocation Attributes for Entries under cn=tasks”.
