From KDE UserBase Wiki

Options for backup are found in the Backup tab. Nepomuk is capable of creating regular backups of data that could not be restored otherwise. You can choose to have backups made automatically at regular intervals, or you can make a backup manually. There is also an option to restore a backup. Automatic backups are stored in $KDEHOME/share/apps/nepomuk/backupsync/backups/.
