I've noticed a new item under Applications -> System Tools: Nepomuk Backup.
I haven't installed it, and it just showed up recently.

Why is it there and why was it installed (possibly with some other KDE program) without my consent?
Is it safe to remove it?

Nepomuk Backup

It is probably a dependency for a program that you installed (probably KDE based), as far as I know you cannot remove it without affecting the application.

Have a look at the page project and the wiki entry for the framework.

You can check what packages depend on that one using apt-rdepends (install it if you don't have it):

Usage for checking is apt-rdepends -d <nameofpackage>, other options can be found on the man() page for rdepends.
