Restoring your Talend Data Preparation instance

After backing up your Talend Data Preparation instance, you can restore your database and configuration at any time.

In order to restore your backed up files, you need to paste them to the appropriate location in the Talend Data Preparation installation folder.

Procedure

Start your MongoDB instance.
Stop your Talend Data Preparation instance.
To restore your MongoDB, open a command prompt window and execute the following command:
mongorestore -h <source_mongodb_host>:<source_mongo_port> -d<source_database> -u <source_mongodb_user> -p <source_mongodb_password> dump\
To restore your datasets, replace the content of the folder specified in the dataset.content.store.file.location property of the <Data_Preparation_Path>/config/application.properties file, with your backed up copy.
To restore your custom configuration, replace the content of the <Data_Preparation_Path>/config folder with your backed up copy.
To restore your log files, replace the content of the <install_folder>\dataprep\data\logs folder with your backed up copy.
If you have installed and used Talend Dictionary Service to create custom semantic types, or update the existing ones, complete the following steps:
1. To restore your custom semantic types, replace the content of the folder specified in the dataquality.indexes.file.location=<preferred_location>/org.talend.dataquality.semantic property of the <Data_Preparation_Path>/config/application.properties file with your backed up copy.
2. Restore the Talend Dictionary Service server. For further information, see Restoring Talend Dictionary Service.

Talend Data Preparation now uses the source files, as well as the configuration, that you had previously saved.
