Backing up Talend Data Catalog on regular basis is important before upgrading or to recover from a data loss scenario or any other causes of data corruption or deletion.
Talend Data Catalog Application Server requires the connection to an existing database server for metadata storage.
This document describes the instructions to perform a full database backup and restore.
The objects from the backup are restored into the same database later. Always use the same database software version to perform the backup and restore.
