Low quality photos in Lightroom online

Agreed, and also a very high-speed upload Internet service! My ISP provides a 100Mb/S (12.5MB/S) download speed, but only 33Mb/S (4.1 MB/S) for upload. Even with this  fast Internet connection it would take almost 3 days to upload 1.0 TB of image files.

For professional photographers like yourself that shoot high volumes of image files it simply isn't practical with the current Internet backbone speeds. Then there are the issues of confidentiality and possible loss of some or all images due to an Adobe storage server HW/SW failure, or security breech. So you need to keep a local copy and a local backup copy. Even then I question what might happen if some image files in the "Cloud" simply become corrupted due to HW/SW storage server issues. How do you handle that to get a non-corrupted local backup copy synced to the server. I'm not am IT expert, but until LR has a Local to Cloud file checksum verification "built-in"–This is a disaster waiting to happen! Given that Adobe hasn't added multi-user catalog access to LR it's unlikely they'll implement checksum verification. Peace!
