It does keep a local cache so you can use it while offline.
Ok thanks so I guess the Catalog info is stored in the Cloud and does that info utilize some of the storage availability.
AFAIK, the database doesn't count towards cloud storage space.
Hi, just learning as much as I can (newbie but love to soak it all up).
If LRCC keeps a copy in the cloud (which I believe you of course Victoria!), it brings two questions to mind:
1. What does LRCC prompt you to backup your catalogue? Seems like this isn't required/redundant.
2. I wonder what happens if you delete your local cached copy (i.e.: simulate a lost/corrupt laptop)
3. In theory, you could make a change offline on your laptop, and online say with your iPad. I wonder which wins when you bring your laptop online. ideally LRCC would make another copy or indicate (like when you make a change it PSCC it increases the file count for that image).
Good tests...someday when I have time unless someone knows!
1. It doesn't even ask.
2. Yes, I've done that multiple times. It just downloads a new copy from the cloud.
3. Whichever was done last (although I agree some kind of conflict resolution could be useful - request it at Lightroom CC | Photoshop Family Customer Community )
I’m trying to move my catalog to my external HD because I don’t have space on my very old MacBook air, but every time it just downloads creates a catalog in the pictures folder again. Is there anyway to get Lightroom cc to read the catalog from my external HD?

It's not currently possible to have the catalog in any location other than the default location on the system drive. The best you can do is move the slider (in the Preferences>Local Storage tab) all the way to the left, i.e. to 0%. That way only the catalog will be taking up space on the drive, there'll be no cached previews, although this will mean slower performance as you browse images as the original will have to be downloaded each time. Of course you could store the originals locally on a different drive, which would give you the performance back.
Thank you very much for your help!
