Hi,
Whenever I want to validate my backup file I try to import it in a working Virtual DataPort Server. For example, I have a test virtual database created in my Virtual DataPort Admin tool to import the backup and check if it goes fine.
To take the backup I use the Import/Export scripts available in the Denodo Platform Installation. By default when you execute the scripts on the command line by passing the parameters with necessary values it returns a status code "0" if no errors are found and it returns status code "1" if errors are encountered. This will help me to validate if it's a working backup.
I would like you to refer to the official documentation on [Use of the Import/Export Scripts for Backup](https://community.denodo.com/docs/html/browse/6.0/scheduler/administration/appendix/use_of_the_importexport_scripts_for_backup) for more information.
If you are a licensed user, you can also use the “Denodo Testing Tool” to check if everything works fine when you import the backup file. You can find more information about this tool in the document “Denodo Testing Tool - User Manual” which is available in the “doc” folder of the downloaded zip file that contains this tool.
Hope this helps you!
