Error during Exporting a space

SaravanaKumar_bq49sy

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.
