Looking for workflow and file backup advice on the iPad Pro. I am getting ready to replace my 2011 iMac 27". The hardware landscape in 2019 is very different from 2011. I use my iMac 70% for casual editing in Lightroom and social media sharing. The rest for Apple Photos library, web, email, Excel and Word. My iMac has 1TB internal storage (40% full after 8 years) and external HDD backup using Time Machine. The thought occurred to me: can the new iPad Pro satisfy my needs? It's a heck of a lot smaller and convenient for casual editing. I don't like being locked away in the office while editing. Since the iPad does not easily accommodate an external HDD, my main concern is with backup storage. Just like my iMac has a backup drive today, I want ONE backup source for EVERYTHING on my device. I don't want to have to split LR backups from everything else on the iPad. If I'm using LR CC, how does backup work? If I bought iCloud storage, could I put all my LR files there along with my Apple Photos library?
