Here's the recording of my live Lightroom Q&A webinar on April 2nd, 2022 for Education Center members.
A question from Richard Gaston about backing images up to the Adobe Cloud led to a discussion about how Lightroom Classic and the cloud (mobile) version of Lightroom integrate, and also about different strategies for backing up images and your Lightroom catalog. (You'll find that from around the 24-minute mark to the 56-minute mark.)
Toward the end of that discussion, Jim White linked to the Lightroom Queen (Victoria Bampton) website, noting that she had lots of information about backing up Lightroom there. Here's a link to a recent blog post from her about backing up.
Thanks to everyone who attended live! It was nice to see so many familiar names. I hope you all enjoyed it and learned something. And thanks for all the great questions!
