Do people use Lightroom as a way of archiving their photos?
I know that we have Lightroom Mobile, but it seems to be a way of sharing work in progress, rather than a longer-term way of storing and accessing your pictures.
Similarly, Behance, which is presumably built on top of Amazon's S3 service, offers quite restrictive storage limits for the sort of person likely to have enough pictures to make Lightroom worthwhile. Again, it seems to be aimed at "creative professionals" for sharing projects, rather than a comprehensive solution for photographers.
Amazon is offering cheap unlimited storage for photos, but in a way that makes the service suitable only for backups. Dropbox is good for photos's but expensive. MS's OneDrive offers 1Tb / unlimited photo storage, but for at least some types of subscription, the number of files stored is limited to 20,000, which makes it less useful for people with photo libraries. Google seems to be thinking about how best to serve the photography market, reversing the unsuccessful integration of their G+ and Picasa offerings. Apple has the right answer, but at an unaffordable price. Services like Mylio (again, presumably built on top of S3) also provide a great solution, but with size/price limitations for photographers.
Lightroom appears to be ignoring all of these developments, providing little proper integration with any of these industrial strength services, assuming that Lightroom Mobile, with all its limitations (I have still not managed to upload 1,000 photos from my iPad back to Lightroom) is an acceptable answer.
What do people use to backup their photo libraries and to share them? What part does Lightroom play in the process? What am I missing?
