How to do full Backup and Restore ADAudit Plus correctly
Hi!
ADAudit Plus 6.0.0 was installed with PostgreSQL. Recently, an unknown failure occurred in the web interface and the "User Work Hours" report when generated returns an error that a failure occurred inside the system. In event logs, if you try to view SQL queries and directly execute them in PostgreSQL, they are executed successfully! So the problem isn't in the database? Since version 6.0.0, the data engine-xcode component has been added https://www.manageengine.com/products/active-directory-audit/help/dataengine/overview.html which also stores data?! Does it also need to be checked? We spent several days restoring ADAudit Plus 6.0.0: the previous copy of SQL was also returned to the file system. Fixed. Updated the patch to 6.0.5.
Question - how do I make a full copy?
pg_dump? cp ManageEngine\ADAudit Plus\apps\data engine-xnode? how should I reserve hsqldb?
Question - how to restore it correctly?
