Cannot backup app via Astro - (private) app? I was just about to backup an Android application via Astro app, when I saw that there is no checkbox in the right side, but just a title saying (private). 

What does it mean? How can someone restrict an app to be backed up? Is there a way to backup the app anyway?
Private means you can't back it up. The developer decided that.

Some apps ignore it


FileExpert &lt;- my favourite
EStrongs File Explorer


Not a file manager, but also Titanium backup
