Comment 2 for bug 781428

Just wanted to say that, after running so many backups recently to test out that other bug and finding that the initial scan itself takes quite a few hours on my data, I can really see the utility of a proactive notification system like this. I believe Apple's Time Machine works in a similar fashion, by monitoring changed files.

Doesn't dbus (or some other Gnome component) provide notification hooks for filesystem changes? If I'm not mistaken, I think a few media management applications, e.g. Banshee, use this to keep their libraries up-to-date.
