Installation and Upgrade

Backing up a Talend Dictionary Service instance includes backing up the MongoDB which stores all the semantic entries.

Before starting the backup procedure, you are advised to copy the dump file at <path_to_installation_folder>/dq_dict/database/dump and save it in a place of your choice to keep a copy of the initial data. This dump file has the by-default semantic types.

Before you begin

  • Set up the environment variable for mongodb. For example, add the below path to your user variables:



  1. Stop your Talend Dictionary Service instance.
    You can do the backup while the instance is running, but you are advised to choose a period of low activity.
  2. Start MongoDB.
  3. Open a command prompt window and execute the following commands to backup the current Dictionary service to a dump folder:
    On Windows:
    • <path_to_installation_folder>/dq_dict/database/semantic-dictionary-export.bat
    On Linux:
    • <path_to_installation_folder>/dq_dict/database/
  4. To back up the configuration files, make a copy of the <path_to_installation_folder>/dq_dict/apache-tomcat/conf folder and save it to a secure place.
  5. If you have made any changes to the predefined semantic types using Talend Dictionary Service, you need to back up the changes stored in the tds folder. For further information, see Backing up a Talend Data Stewardship instance.


The backup of the current Dictionary service is completed and the file is saved at <path_to_installation_folder>/dq_dict/database/dump.
