Could not restore the backup to a MySQL database - Reason: The database schema could not be restored.


After running the restore client to a newly created MySQL DB instance, the following appears in the <path/to/backup/client>/log/atlassian-sbc-YYYY-MM-DD-HHMM.log:

The jdbc.url in use is incorrect. Please make sure you specified all the parameters, specially the sessionVariables. If your default db engine (check with mysql> show engines;) is not InnoDB and this parameter is not specified on the JDBC URL, the exception above will be thrown. An example of the complete JDBC URL can be found in:

    • stash.home=/var/atlassian/application-data/stash.. So:
    • rm /var/atlassian/application-data/stash/* will do the work.
  • Recreate the database as defined on
