How do I download Database from Azure Data Explorer?

Question

How do I download Database from Azure Data Explorer?

Nathan Sommer 40

Hello,

I'm trying to download my database to a hard drive as a backup, however I'm having a hard time downloading the Data Explorer database. I know I can download it by runnning a KQL script for each table, but I have 60+ tables, and don't want to have to run through each one for a backup. Is there any other way to download?

Thanks,

Nathan Sommer

At this time, there is no native option to back up an entire Azure Data Explorer (ADX) database as a single downloadable file. We understand this limitation can be challenging when working with a large number of tables.

If your intention is to recover the database in case of any accidental deletions, you could mitigate the deletions through disaster configurations:

Active-active-active configuration

Active-Active configuration

Active-Hot standby configuration

On-demand data recovery cluster configuration

For more details, refer to Business continuity and disaster recovery overview - Disaster recovery configurations.

Also, you cannot recover a cluster or database in case of any accidental deletions until you put a lock at resource level.

For more details, refer to Lock resources to prevent unexpected changes

If this is a feature you'd like to see in the future.

Thanks for posting your question in the Microsoft Q&A forum.

However, there are several practical methods to export your data for backup purposes:

Continuous Export to External Table

Create an external table that points to your desired backup storage, then set up continuous data export for each table you want to back up. This allows data to be periodically exported to the external table, ensuring your backup is always up to date. then use tools like LightIngest to ingest the exported data back into Azure Data Explorer if needed.

Scripted Export of All Tables

Write a script that iterates through all your tables, runs KQL queries to export each table’s data, and saves the results to your local hard drive or cloud storage. While you mention having 60+ tables, scripting this process is feasible and can be scheduled or run on-demand.

Client-Side Export via Web UI or Kusto Client Libraries

You can run queries and export results to CSV or other formats. However, this is manual and not practical for a large number of tables

Thank you for your response.

Would you by chance have any examples of the scripting? I have a list of tables, not sure how to script the KQL queries for each table.
