So I use the Store Presets with Catalog option in prefs. Then my presets and all my LR related data, and all my images on a dedicated drive are super easy to backup and clone. I don't like that at least on Mac, they live deep in the "System Folder".
DCP profiles are a different story unfortunatly. They don't but should have a similar option. So I simply make a Symbolic Link to the folder where they reside so a copy of them is also on this one drive and again, they all get backed up, every night while I sleep to both the Cloud backup and another HD. At least on Mac, I use Chronosync.
And NO you are not stupid to be afraid of losing your important data. Be it your catalog, presets, profiles or images. Having all this on one dedicated drive makes cloning that drive to others a snap.
