Lifecycle Query Engine provides the ability to back up
and restore indexed data. This copy may be used in the future to restore
Lifecycle Query Engine to a past state.
About this task
There are two ways to back up LQE:
- Scheduled Backups: The backups can be scheduled to occur
on specific days and time. To schedule backups, log into LQE and
then go to Administration > Backup. Click
the Edit link to schedule backups or change
the schedule of backups.
- One Time Backup: You can perform a one time backup by clicking
the Backup Now link on the LQE Administration
> Backup screen. Once requested the backup is started
as soon as all the current activity finishes.
Note: You will need to specify a directory on the server as the
backup directory. This directory must be created before you can schedule
backups or perform a one time backup.
What is backed up?
In
the backup directory, you will see a timestamped directory or directories
(if more than one backup has been performed) containing the following
directories:
- indexTdb: This directory is a backup of the
LQE index database: <JTSInstallDir>\server\conf\lqe\indexTdb
- metadata: Contains backup properties and
settings. The content of this directory does not need to be restored.
- textIndex: This directory is a backup of
the LQE lucene index which is used for full text searching of the
triples: <JTSInstallDir>\server\conf\lqe\textIndex
