Just to be clear here... Your Lightroom catalog is very important but is not backing you your Photos. (which I know you said at the end. I am just emphasizing)
Your LR catalog contains your photo edits, metadata and history... but is not your original files. Backing it up is very important but is only part of the story. Putting your Lightroom catalog backups on Dropbox is a great and should be done by everyone. (Again just not your active catalog.)
