Lightroom CC: Backup entire LRCC catalog?

I have put Lightroom catalogs on Dropbox without any issues. As with any database, if you open it on a 2nd computer before all the links are consistent, you risk losing everything. And you have to figure out how to not sync the cache files (or pay for uploading, downloading and storing a bunch of redundant data).

I believe LR CC keeps a copy of your catalogue locally.  My copy (on an Mac) is in the pictures folder:  Lightroom Library.lrlibrary

I know LR Classic keeps the catalog local, but I don't think the new LRCC does the same. 

Your catalog and full size originalimages are backed up in the Lightroom CC cloud.

If you want to keep all copies locally and backed up in the Lightroom CC cloud, open Preferences > Local Storage, and check "Store a copy of ALL originals locally"



Backing everything up to another cloud system would be a 3rd, redundant black up. We don't recommend syncing images and catalogs to 3rd service because the sync engines compete with one another in such a way that the performance on the system would be compromised. 

That's a step  right direction, Jeffrey, but I don't ever want my files to be stored locally -- I want to be able to copy them from LRCC cloud to some other cloud storage system. 

I was able to save the top folder of collections and export it as a catalog.  Then go into Lightroom CC and migrate the catalog.  All pictures were brought in with folder structure.  Thank you very much!!!
