Hi Tony,
It’s pretty hard-coded in at the moment, but next version it won’t be – it’ll still be fixed for most people though. The default is in the WordPress content folder (wp-content usually) in a subdirectory called backups.
You can download the pre-release here:
https://downloads.www.ads-software.com/plugin/wponlinebackup.zip
It’s the developer version from the plugin page
With this version installed, click General Settings, then edit the URL in your browser so instead of it saying “§ion=settings” at the end, it says “§ion=advanced”. This is the hidden advanced settings control panel.
On the advanced settings, with this version, you will see backup_directory. Tick the checkbox (which tells the plugin “override default”) then enter your own path. Then save settings.
It will then begin using that directory for backups.
Note the directory needs to exist and be accessible before it will let you change the backup_directory to it.
Regards,
Jason
