The task backend provides a mechanism for processing tasks in the OpenDS Directory Server. Tasks are intended to provide access to certain types of administrative functions in the server that may not otherwise be convenient to perform remotely. Tasks that are currently available for use provide the ability to backup and restore backends, to import and export LDIF files, and to stop and restart the server. The details of the task to perform are held in an entry that is added below the root of the task backend, and then the task backend is responsible for decoding that task entry and ensuring that it is processed as requested. Tasks may be invoked immediately, but they may also be scheduled for execution at some future time. It is also expected that task backend will be given the ability to process recurring tasks, which can be used to help ensure that maintenance operations (e.g., backups) are performed automatically on a regular basis. ds-cfg-task-backend ds-cfg-backend org.opends.server.backends.task.TaskBackend enabled This specifies the path to the backing file for storing information about the tasks configured in the server. It may be either an absolute path or a path that is relative to the base of the OpenDS Directory Server instance. ds-cfg-task-backing-file This specifies the length of time that task entries should be retained after processing on the associated task has been completed. 24 hours ds-cfg-task-retention-time This specifies the e-mail address to use as the sender (i.e., "From:") address for notification mail messages generated when a task completes execution. The default sender address used will be "opends-task-notification@" followed by the canonical address of the system on which the server is running. ds-cfg-notification-sender-address
