Error during Exporting a space
Asked by SaravanaKumar:

We tried taking a backup of a space using Export space option.  

But export failed saying couldn't backup the database  

The error we found by analyzing the logs shows that  

com.atlassian.confluence.importexport.ImportExportException: Couldn't backup database data.
