This backup process is used for support purposes, to deliver from development to production environments or to migrate to a new type of database such as PostgreSQL to Oracle.
Talend Data Catalog stores all the data in the database (RDBMS).
The backup/restore feature implemented in Talend Data Catalog does not replace the full database backup and restore because it does not contain critical administration data, such as logs. For more information on the full database backup and restore processes, see Backing up and restoring your Talend Data Catalog instance.
This process cannot be used to migrate or upgrade Talend Data Catalog. For more information, see the Migrating Talend Data Catalog 7.1.2 to 7.3.
