Two possible methods to resolve this issue:
1. Identify the designated database backup location, fix the access issue, and re-issue the online backup command.
2. Change the database backup path, re-start the DSA, and re-issue the online backup command.

set dxgrid-backup-location = "<backup_file_location>";
