Backing up and restoring Lifecycle Query Engine and Link Index Provider (LDX)
You can back up and restore data that is indexed by Lifecycle Query Engine (LQE) or Link Index Provider (LDX). The copy of the indexed data can be used in the future to restore LQE or LDX to a previous state.
Note: The server on which you
are creating the backup must be mapped or mounted - URIs are not supported.
Before you begin
Ensure that the disk space is at least three times the current size of the indexes under <JTSInstallDir>\server\conf\lqe or <JTSInstallDir>\server\conf\ldx.

the following directories:
- datasets: This directory contains the following directories:
- In LQE and LDX:
- default\indexTdb: Backup of the LQE or LDX index database: <JTSInstallDir>\server\conf\lqe\indexTdb, or <JTSInstallDir>\server\conf\ldx\indexTdb
- default\textIndex: Backup of the LQE or LDX Lucene index that is used for full text searching of the triples: <JTSInstallDir>\server\conf\lqe\textIndex or <JTSInstallDir>\server\conf\ldx\textIndex
- version\indexTdb: Backup of the Tracked Resources Set (TRS) version of every artifact
- Only in LQE:
- shapes\indexTdb: Backup of the resource shapes index
- shapes\textIndex: Backup of the LQE Lucene index that is used for full text searching of the resource shapes
- history\indexTdb: For historical metrics
- history\textIndex: For historical metrics text searches
