public final class BackupTask
extends Task

This class defines a Directory Server task that can be used to back up one or more Directory Server backends.

NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

The properties that are available for use with this type of task include:

• The path to the directory in which the backup should be placed. If multiple backends are to be backed up at once, then this should be the parent of the backup directories for each backend. This must be provided when scheduling this task.
• The backend IDs of the backends to archive. If this is not provided, then the server will attempt to back up all supported backends.
• The backup ID to use for the backup. If this is not provided, then the server will generate a backup ID.
• A flag that indicates whether the backup should be an incremental backup (if the backend supports that capability) or a full backup.
• The backup ID of the existing backup on which the incremental backup should be based. If this is not provided and an incremental backup is to be performed, then it will be based on the most recent backup in the backup directory.
• A flag that indicates whether to compress the contents of the backup.
• A flag that indicates whether to encrypt the contents of the backup.
• A flag that indicates whether to hash the contents of the backup to use as a checksum for verifying the integrity of the backup.
• A flag that indicates whether to sign the backup hash in order to prevent anyone from tampering with it.

Constructor Detail

BackupTask

public BackupTask()

Creates a new uninitialized backup task instance which should only be used for obtaining general information about this task, including the task name, description, and supported properties. Attempts to use a task created with this constructor for any other reason will likely fail.

BackupTask

public BackupTask(java.lang.String taskID,
                  java.lang.String backupDirectory,
                  java.lang.String backendID)

Creates a new backup task with the provided information.

Parameters:

taskID - The task ID to use for this task. If it is null then a UUID will be generated for use as the task ID.

backupDirectory - The path to the directory on the server into which the backup should be written. If a single backend is to be archived, then this should be the path to the specific backup directory for that backend. If multiple backends are to be archived, then this should be the parent of the directories for each of the backends. It must not be null.

backendID - The backend ID of the backend to back up. It may be null if all supported backends should be backed up.
