I used define( 'HMBKP_PATH', '' ); to modify the default location for backups. This works and backups are saved outside the public_html directory. Unfortunately, when I click on a Download link to a backup, I get a 404 error. Since the path is from /home, the web server can't find the file.
Does this mean that if you use HMBKP_PATH to store the backup files outside the web space that you can't download them from the links in BackUpWordPress?
