Okay I'm reformatting my computer, and I want to make sure I backup lightroom properly this time. Last time, I must of did something wrong, cause it had the thumbnails but told me the images were missing, and once I restored the image database, I had lost all my edits, and had to re-PP like 1300 photos So I've saved the image database on two other hard drives. And I saved the catalogue on both those hard drives too. I feel this is what I did before, because I thought all you needed was the image database, and the catalogue carries all the PP edits. Is there anything I'm missing?
